Análisis de una política pública de combate a la pobreza y desarrollo rural: Proyecto estratégico para la seguridad alimentaria en el estado de Puebla 2010.
Provedor de dados: 32
Autores: González Ramos, Efraín.
El problema de la pobreza y el desarrollo rural en nuestro país es un tema que debe estar presente en la agenda de investigación de las universidades y centros de investigación especializada, así como ser un problema de atención prioritaria de los gobiernos en sus distintos niveles. El desarrollo de investigaciones en la materia que conduzcan al rediseño o elaboración de nuevas políticas públicas, constituirían el mejor binomio para logar superar dichos retos. El presente trabajo hace una revisión del Proyecto Estratégico para la Seguridad Alimentaria (PESA) desde la perspectiva del Análisis de las Políticas Públicas, mostrando los mecanismos de focalización del programa, la correspondencia con los postulados teóricos que respaldaron su elaboración y los...

Autores: Lunkes, Bruna; Balk Brandão, Janaína; Dorr, Andrea Cristina.
This paper seeks to identify the socioeconomic profile and consumer behaviors of a family farming retail market. This research was carried out in Santa Maria, Rio Grande do Sul state, Brazil, and is classified as exploratory/descriptive, obtained by secondary data analysis, application of questionnaires and bibliographic research. Questionnaires were applied to 68 retail consumers of a family farmers cooperative in the year 2021. Three distinct public profiles were identified, each with their own characteristics called young, adults and elderly. The highest degree of satisfaction was in the item “service” and the lowest average was in the item “price”. Through the correlation test of variables run with the Spearman correlation coefficient, it was found...

The  Food Acquisition Program from the perspective of farmers: a case study in Amaraji – Pernambuco
Provedor de dados: 194
Autores: Silva, Rodrigo Rogerio da; Souto, Aline de Souza.
Family farming is largely responsible for food production in Brazil. The scale of production and logistical arrangements of family farmers make marketing difficult and demand public policies. Through the Food Acquisition Program (PAA), the state bought food produced by family farmers, organized in associations and cooperatives. This study presents the perception of farming families, in Pernambuco. It expounds the limits and possibilities of the PAA. This is a case study. We chose thenon-probabilistic sampling method for data collection, using observations and semi-structured interviews, applied through convenience sampling. Participation in the Program allowed conditions for access to goods and services, through the market. The results show that among the...

Comportamento alimentar e dieta de serpentes, gêneros Boiruna e Clelia (Serpentes, Colubridae)
Provedor de dados: 76
Autores: Pinto,Carla da Costa; Lema,Thales de.
Boiruna maculata Boulenger, 1896 and Clelia rustica (Cope, 1878) were observed in captivity feeding snakes and rodents, respectively. Both species have shown a similar procedure in relation to the prey. Major behavior differences among the two species were: rodents killed before being swallowed, and snakes were mostly swallowed alive; both species are able to find the rodents head faster than the snake one; the coils formed during constriction were also used to hold the prey, specially the last coil, while swallowing rodents. Informations on stomach contents was gathered by dissection of preserved specimens of Clelia clelia (Daudin, 1803) and C. plumbea (Wied, 1820) were also included in the dietary study. The majority of preys consisted on snakes and...

A domesticação de plantas nativas do Pantanal.
Provedor de dados: 14
Autores: JORGE, M. H. A.
Os interesses do homem em domesticar certos vegetais que fariam parte do seu dia-a-dia, sejam em rituais, sessões de cura, ou até mesmo como parte da sua dieta, estão registrados desde milhares de anos. Estas plantas passaram então por um processo conhecido como seleção, e durante vários anos, foram cultivadas e melhoradas para atender os interesses do homem, no caso de grãos tamanho e número. Atualmente, o homem ainda utiliza a domesticação para muitas espécies que possuem potencial econômico de exploração, seja medicinal, alimentício, verterinário, entre outros. Técnicas mais modernas impulsionaram esse processo de seleção, agilizando assim a condução e obtenção de resultados. Considerando que o Pantanal possui imensa diversidade de plantas que na sua...

Microparticulate feeds for Penaeid larvae
Provedor de dados: 5
Autores: Kanazawa, A.
The mass production of penaeid larvae still depends on live foods such as diatoms, Chlorella and Artemia . However, it requires much facilities, maintenance expenses, and labor to produce a desired amount of life foods safely and constantly. Also, the nutritive value of planktonic organisms is occasionally variable and this makes the use of live food for mass culture restrictive. Therefore, it is necessary to develop microparticulate diets as a substitute for live foods to further increase the productivity of seed for shrimp culture.

Influence of food density and temperature on ingestion, growth and settlement of Pacific oyster larvae, Crassostrea gigas
Provedor de dados: 5
Autores: Rico Villa, Benjamin; Pouvreau, Stephane; Robert, Rene.
Ingestion, growth and metamorphosis of Pacific oyster, Crassostrea gigas, larvae were studied under controlled conditions of food density and temperature using a combination of a flow-through rearing system and a hydrobiological monitoring device. In a first experiment larvae were exposed to three different phytoplankton densities (12, 20 and 40 cells &amp;#956;l-1) while in a second trial larvae were reared at five different temperatures (17, 22, 25, 27 and 32°C). Both food concentration and temperature significantly affected the larval physiology throughout the entire development from D-veliger to young spat. Larvae survived over a wide range of both environmental parameters with high survival at the end of experiments. The feeding functional response...

Autores: Nguyen, Thi-my-huong.
The main objective of this study is the valorisation of by-products coming from processed tuna (Thunnus albacares). Therefore, enzymatic hydrolysis was selected, using an industrial large spectrum protease (Protamex). In a first phase, hydrolyses of these by-products (heads, tails, viscera) were carried out for long periods of time (12h) in order to establish the kinetics of the proteolysis of those different by-products and to obtain the approximate composition of the different resulting fractions and to determine the conditions which would allow the  valorisation of these  fractions.  In a second phase the valorisation in animal nutrition (shrimp culture) and in human nutrition (fish sauce) of the fractions coming from the hydrolysis of the head of tunas...

Determination of gender in the pearl oyster pinctada margaritifera
Provedor de dados: 5
Autores: Chavez-villalba, Jorge; Soyez, Claude; Huvet, Arnaud; Gueguen, Yannick; Lo, Cedrik; Le Moullac, Gilles.
The pearl industry in French Polynesia is based on exploitation of natural stocks of the black-lip pearl oyster (Pinctada margaritifera); it generates an annual turnover of 90 million euros. Improvements in pearl quality need genetic studies to improve the populations. This pearl oyster is a protandric species, where the sex-ratio normally is biased towards males. There is an increasing interest in gender control to find the mechanisms to augment female proportions for management purposes. This review summarizes information on exogenous and endogenous factors regulating gender in this and other bivalves and concludes that P. margaritifera is a protandric hermaphrodite, developing as a male during the first two years and without evidence of an effect from...

After four weeks' stabulation, at temperatures ranging from 30°C to 10°C for a given level of food (2.10 cells of Chaetoceros calcitrans.1(-1) ), a study of the growth and evolution of the biochemical contents of the oyster Crassostrea gigas showed a negative effect of high (30°C) and low (10°C) temperatures on growth; levels of total glucid and glycogen were inversely proportional to temperature and related to gametogenesis. At the same time measurements of the filtration rate, respiration and food consumption done at different levels of food (10(6) to 8.10(7) cells.1(-1) showed a better adaptation of the oysters to 20°C after one month.

Adenylatc Encrgy Charge (AEC) values of Crassostrea gigas (9 and 18 months old) cultured in ponds in Marennes-Oléron Bay (Atlantic coast, France) are reported. Two ponds were loaded with two different initial oyster biomasses in order to obtain different food conditions. The growth of oysters was different in the two ponds which corroborated the effectivences of attaining different food conditions. AEC level was different depending on the pond and was therefore related to food availability per unit oyster biomass. Well-fed oysters exhibited greater AEC values than poorly-fed oysters, throughout thc study. Information on nutritional situations for wild or cultured populations can therefore be obtained by AEC. In cach pond, the seasonal AEC variations were...

110 Vibrio strains were isolated, at various times of the year, from samples of sea-water supply, breeding-tank water and discarded fish used as food at the breeding stations. From the results obtained by the biochemical and cultural tests, it was possible to identify most of the isolated strains as Vibrio anguillarum . Strains with intermediate characteristics, above-all positive saccharose, proved to be numerous. The authors discuss the occurrence, in particular environments such as those being studied, of atypical or intermediate vibrio strains which are difficult to classify.

Background Life in the darkness of caves is accompanied, throughout phyla, by striking phenotypic changes including the loss or severe reduction in eyes and pigmentation. On the other hand, cave animals have undergone constructive changes, thought to be adaptive, to survive in this extreme environment. The present study addresses the question of the evolution of growth in caves, taking advantage of the comparison between the river-dwelling and the cave-dwelling morphs of the Mexican tetra, Astyanax mexicanus. Results A sclerochronology approach was undertaken to document the growth of the species in these two very distinct habitats. Scales from 158 wild Astyanax mexicanus specimens were analyzed from three caves (Pachón, Tinaja and Subterráneo) and two...

Croissance de jeunes palourdes (Venerupis semidecussata) en nurserie et en mer en fonction des conditions d'élevage
Provedor de dados: 5
Autores: Lucas, Albert.
The japanese palourde Venerupis semidecussata was reared in the Bay of Brest, using hatchery reared spat. Experiments were performed with individuals of lenght 2 to 10 mm raised in a nursery, using raceways with slow running water enriched with unicellular algae, And also with individuals of lenght 8 to 20 mm raised at sea in suspended culture. It was observed that growth depends upon four groups of factors : (1) the functioning and equipment of the raceways, (2) the quantity and quality of the food, (3) the temperature and (4) various physico-chemical factors. When the equipment is satisfactory and when the physico-chemical fac­tors are normal for the species in question, the rate of growth depends essen­tially on the quantity of food, provided that the...

In a recent report by risk assessment experts on the identification of food safety priorities using the Delphi technique, foodborne viruses were recognized among the top rated food safety priorities and have become a greater concern to the food industry over the past few years. Food safety experts agreed that control measures for viruses throughout the food chain are required. However, much still needs to be understood with regard to the effectiveness of these controls and how to properly validate their performance, whether it is personal hygiene of food handlers or the effects of processing of at risk foods or the interpretation and action required on positive virus test result. This manuscript provides a description of foodborne viruses and their...

Adaptation of digestive enzymes to dietary protein, carbohydrate and fibre levels and influence of protein and carbohydrate quality in Penaeus vannamei larvae (Crustacea, Decapoda)
Provedor de dados: 5
Autores: Le Moullac, Gilles; Van Wormhoudt, A; Aquacop, Aquacop.
Activity of digestive enzymes (trypsin, chymotrypsin and amylase) was studied in relation with food in Penaeus vannamei larvae first stages. Microparticles containing casein involved the decrease of soluble protein content and enzyme activities. Specific trypsin activity but not chymotrypsin was correlated (p&lt;1%) to casein level between 10 and 60% in microparticles. Cellulose fibres in food seemed to have little effect on digestive enzymes. Starch, between 1 and 20% in microparticles, had no influence on specific amylase activity. The effect of different feeding conditions were also tested on growth. No clear relationship between growth and enzyme is established since only trypsin is concerned in the case of a casein dose effect in the food. The protein...

L'élevage larvaire intensif du loup Dicentrarchus labrax. Influence de la lumière, de la densité en proies et de la température sur l'aluminium, sur le transit digestif et sur les performances zootechniques
Provedor de dados: 5
Autores: Ronzani Cerqueira, Vinicius.
Several sea bass-rearing experiments were performed from hatching trough metamorphosis. The rearing units employed were 500 1 polyester tanks, where flow rate and temperature of seawater, light and suitable food (rotifer and artemia) were controlled. Stock density ranged between 50 and 100 larvae per liter.  Individuals held in tanks with internal black walls developed faster and had a greater survival rate than those in white tanks. This suggests that a better contrast between preys and background assists the larvae to see food organisms more clearly.  The sea bass larvae search for food is based only in vision and not trought mechanoreceptors or chemoreceptors. It was very difficult to evaluate the light intensity (50-5000 lux) influence on feeding,...

Remodeling of membrane lipids in gills of adult hard clam Mercenaria mercenaria during declining temperature
Provedor de dados: 5
Autores: Parent, G; Pernet, Fabrice; Tremblay, R; Sevigny, J; Ouellette, M.
In a previous study, a major remodeling of lipids, consistent with the theory of homeoviscous adaptation, was observed in the juvenile hard clam Mercenaria mercenaria during a temperature reduction from 24 to -1 degrees C. In addition, the lipid remodeling varied between genetically distinct lines of hard clams. The present study examined whether adult hard clams originating from different locations and a selectively bred variety show differences related to their genetic characteristics in the remodeling of lipids that normally occur during decreasing temperatures. Wild hard clams from 4 locations in Atlantic Canada and the selectively bred M mercenaria var. notata were held at an aquaculture growout site located at the northern distribution limit of the...

Autores: Orsi,R. O.; Sforcin,J. M.; Rall,V. L. M.; Funari,S. R. C.; Barbosa,Luciano; Fernandes,JR A.
Propolis antibiotic action has been widely investigated. This assay was carried out in order to observe the in vitro antibacterial activity of propolis against Salmonella enteritidis isolated from food and Salmonella typhimurium isolated from human infections. Propolis was collected by Apis mellifera in two regions of Brazil (Mossoró, Rio Grande do Norte State; and Urubici, Santa Catarina State). Both strains survival percentage decreased with time of incubation in Ethanolic Extracts of Propolis (EEP), demonstrating bactericidal effect after 24 hours. It was also observed that EEP from Mossoró was more effective than that from Urubici. The control of the propolis solvent - 70% ethanol - was less effective than EEP, showing only a bacteriostatic effect. We...

Background Environmental devastation threatens the survival of many species, including venomous snakes such as the South American rattlesnake Crotalus durissus terrificus. This observation is based on the decrease of snakes collected and donated to Brazilian research institutes. Nevertheless, some individuals have managed to survive and procreate. The question is how these snakes are adapting in these new environmental conditions.Methods To answer it, the carbon-13 level of rattlesnakes and their feed (either laboratory or wild mice) was evaluated by isotope-ratio mass spectrometry. Thus, rattle segments from 16 adults and 15 offspring of captive snakes, and of three wild newborn C. d. terrificus were evaluated as well as 17 Mus musculus mice captured in...

The gut contents of five juvenile individuals of the loggerhead turtle Caretta caretta (L.) from waters around Madeira, Selvagem Grande (Selvagens Islands) and São Miguel (Azores) were analysed macro- and microscopically. Macroscopic investigations showed that epipelagic salps (e.g., Pyrosoma atlanticum Péron) and gastropods (e.g., Ianthina spp. and Pterotrachea spp.) constituted an important part of the food remains present in these loggerheads. To a lesser extent this also holds for organisms such as goose-barnacles (Lepas spp.). and Idotea metallica Bosc, which live on drifting materials, including algae. Microscopic examination revealed the presence in all turtles of large numbers of nematocysts, deriving mainly from Siphonophora and to a lesser extent...

Provedor de dados: 82
Autores: Chocorosqui,Viviane R.; Panizzi,Antônio R.
The biology of the pentatomid Dichelops melacanthus (Dallas) feeding on cultivated and non-cultivated plants was studied in the laboratory. Nymph mortality varied from ≈ 60 on corn (seed mature) to 77% on wheat (ear immature); no nymphs survived on seedlings of corn or wheat. Nymph developmental time on soybean, corn or wheat (seed, pod or ear) varied from 25.5 to 32.8 days. Body weight at adult emergence was similar and greater on most foods than on wheat ear. Nymphs fed preferentially on soybean (pod immature). On non-cultivated hosts, nymphs showed high mortality (73%) on crotalaria (pod immature); on tropical spiderwort (stem) all nymphs died. Nymphs took longer time to develop on crotalaria and/or on spiderwort than on soybean. Body weight at adult...

This paper reports on the feeding biology of a predatory and of a facultatively predatory nematode, &lt;i&gt;Enoploides longispiculosus&lt;/i&gt; and &lt;i&gt;Adoncholaimus fuscus&lt;/i&gt;, respectively. Both species represent genera which are common and abundant in the littoral of the North Sea and in adjacent estuaries. Observations on the foraging behaviour of both species are given, and for the former species, a range of prey from its natural habitat is identified. Respiration was determined using a polarographic oxygen electrode technique and compared to consumption determined as predation rates on the monhysterid nematode &lt;i&gt;Diplolaimelloides meyli&lt;/i&gt;. The daily C-loss due to respiration accounted for 15% of the measured C-consumption...

A model of nematode dynamics in the Westerschelde Estuary
Provedor de dados: 27
Autores: Li, J.; Vincx, M.; Herman, P.M.J.
We developed a time dynamic model to investigate the temporal dynamics of nematode community in the brackish zone of the Westerschelde Estuary. The biomass of four nematode feeding groups observed from March 1991 to February 1992 is used to calibrate the model. Using environmental data as the input, the model predicts the temporal modification and interrelation of four nematode feeding groups. Nematodes achieve a dominant position in the community because of their lower loss rate (in respiration, excretion and natural death). Predators which are deposit-feeding macrobenthos control the variations of dominant nematodes, such as omnivores and non-selective deposit feeders. Food availability causes modification only for rare nematodes such as epigrowth...

Use and production of microalgae as food for nursery bivalves
Provedor de dados: 27
Autores: De Pauw, N.
The nutritional value of various foods and diets for juvenile bivalves is reviewed and commented. From all foods tested specific microalgues seem to be the most suited for young bivalves. Presently, serious alternatives for replacing living algae by inert, artificial feeds are practically inexistent, though research efforts are made in this direction. The various microalgae production-systems used for feeding juvenile bivalves are also reviewed. A literature survey and the COST inquiry held in 1979 by our laboratory revealed that nearly all commercial enterprises involved in nursery rearing of bivalve molluscs in Europe utilize natural phytoplankton as food. Culturing of the postlarvae is performed either &lt;i&gt;in situ&lt;/i&gt; (in the sea) or in...

Possible Implications for U.S. Agriculture From Adoption of Select Dietary Guidelines
Provedor de dados: 31
Autores: Buzby,   Jean C.; Wells,   Hodan Farah; Vocke,   Gary.
To help Americans meet nutritional requirements while staying within caloric recommendations, the 2005 Dietary Guidelines for Americans encourage consumption of fruits, vegetables, whole-grain products, and fat-free or low-fat milk or milk products. This report provides one view of the potential implications for U.S. agriculture if Americans changed their current consumption patterns to meet some of those guidelines. For Americans to meet the fruit, vegetable, and whole-grain recommendations, domestic crop acreage would need to increase by an estimated 7.4 million harvested acres, or 1.7 percent of total U.S. cropland in 2002. To meet the dairy guidelines, consumption of milk and milk products would have to increase by 66 percent; an increase of that...

As food is an experience good, the market for restaurant meals is a market where the cost of acquiring information regarding quality is relatively high. In such markets consumers often turn to reputation measures to guide purchase decisions. As Australia does not have a longstanding cuisine style of its own, and given Australia has been open to substantial immigration inflows since federation, it represents an especially appropriate market to study regarding the impact of individual restaurant reputation and collective cuisine reputation on meal prices. The following study uses the hedonic price approach to investigate the implicit price of individual reputation indicators, cuisine type reputation indicators, and other objective indicators in the market...

CHINA'S FOOD AND AGRICULTURE: ISSUES FOR THE 21ST CENTURY
Provedor de dados: 31
China's impact on world agricultural markets in coming decades will depend on many factors. Growing income and transition to modern urban lifestyles will increase demand for all foods, but demand will shift toward meat and high-value products. WTO accession may increase openness of China's agricultural trade and allow more imports. An understanding of geographic variations of consumption, production, trade, and policy is critical to understanding the vast China market. Development of transportation infrastructure and market channels will make it easier for food products to reach consumers. China's approach to biotechnology and its reform of institutions for allocating land, labor, and water inputs have important implications for agricultural productive...

Autores: Ferrari,   Emanuele; Cardenete,   Manuel Alejandro; Boulanger,   Pierre; Delgado,   M.C.; M'Barek,   Robert.
The turnover of the EU agri-food sector overtops 2,000 billion Euros a year and employs roughly 22 millions workers. The focus of this paper is on the sectors directly linked to agricultural production and the food industry. Having a comprehensive understanding of extended agri-food economic linkages is critical when designing pertinent policies to deliver the full potential of strong EU agri-food and other bio-based sectors. A more disaggregated view is required. This study stars from a Social Accounting Matrices (SAM) for Spain with a highly disaggregated agricultural sector (AgroSAMs) for the year 2000. This study uses the AgroSAMs in its entire disaggregation, in order to provide a descriptive analysis of the agri-food and bio-based sectors. The limits...

The aim of this article is to evaluate Italian consumers’ acceptance and willingness to purchase GM foods based on the type of benefit (input vs output trait) and product (plant based vs animal based). Two surveys were administered in two consecutive years (2004 and 2005) and the data used to test for possible changes in consumer acceptance. The results of a multinomial logit analysis suggest that on average consumer acceptance for plant-based GM food was higher in 2005. This study confirmed the key role of information strategies to consumers, with the most relevant results being the role distorted information play in raising the consumer’s level of fear and perceived risk. Respondents also place a higher level of confidence on scientists who are generally...

Autores: Fuglie,   Keith O.; Heisey,   Paul W.
Over the last several decades, the U.S. agricultural sector has sustained impressive productivity growth. The Nation's agricultural research system, including Federal-State public research as well as private-sector research, has been a key driver of this growth. Economic analysis finds strong and consistent evidence that investment in agricultural research has yielded high returns per dollar spent. These returns include benefits not only to the farm sector but also to the food industry and consumers in the form of more abundant commodities at lower prices.

A Strategic Perspective on the Impact of Food Safety Standards on Developing Countries
Provedor de dados: 31
Autores: Henson,   Spencer J.; Jaffee,   Steven.
This paper explores the competing concepts of 'standards as barriers' and standards as catalysts' in the context of food safety standards in international trade in agricultural and food products.  It is suggested that food safety standards can act as both a barrier to trade and the basis of competitive positioning for developing countries in international markets.  This suggests that the application of a strategic framework to analyze and assess alternative responses to evolving food safety standards can throw some light on the circumstances under which standards act to prohibit trade or, alternatively, create competitive trade opportunities.  The use of such a framework is illustrated through a brief case study of fish and fishery product exports from...

Simultaneous with the growing demand for sustainable food, statistics in all EU member states report consumption patterns that are characterized by too much fat, overdoses of sugar and a lack of fruits and vegetables. The streams of literature that investigate the factors influencing sustainable food consumption and healthy food consumption are largely separated. However, the question whether there is a positive relationship between consumer behaviour towards sustainable food and consumer behaviour towards healthy food remains largely unanswered. The purpose of this paper is to examine the relationship between the consumption of different types of sustainable food on the one hand, and healthy food patterns on the other.

Exports have been an integral and essential feature of the agriculture and food industry in Alberta. This is a product of the province’s relatively low population and consumption base on the demand side juxtaposed with a large resource base of prime agriculture land for crop production and an abundance of range and pasture for grazing and forage for raising livestock on the supply side. A host of factors influence the disposition of surplus production or exports including global supply/demand balances, relative cost/price relations, structural changes through farm consolidation and scale economies, market access, exchange rates, sanitary and phyto‐sanitary standards and regulations, disease and pest related issues. The inherent nature of agriculture means...

Forecasts of the number of future professionals required for an ongoing safe, efficient US food system are highly important. The demand for adequately prepared higher education graduates must be met by the US Food, Agriculture, and Natural Resources Education System. Without accurate forecasts of the human resource needs of the food sector of the economy, adequate professionals may not be available when needed. This research effort makes use of Bureau of Labor Statistics (BLS) forecasted employment opportunities. The estimation of professionals required in the food and agriculture sectors of the economy is developed by selecting and manipulating data from the BLS model that is relevant to food and agriculture careers.

USING BEST WORST SCALING TO INVESTIGATE PERCEPTIONS OF CONTROL AND CONCERN OVER FOOD AND NON-FOOD RISKS
Provedor de dados: 31
Autores: Erdem,   Seda; Rigby,   Dan.
This research locates a series of risks or hazards within a framework characterized by the level of control respondents believe they have over the risks, and the level of worry the risks prompt. It does this for a set of both food and non-food risks. The means by which this is done is novel and differs from past risk perception analyses in that it asks people directly regarding their relative assessments of the levels of control and worry regarding the risks presented. The cognitive burden associated with people ranking and scaling items in large sets is notoriously heavy and so this study uses an elicitation method designed to make the process intuitive and cognitively manageable for respondents. The substantive analysis of the risk perceptions has 4 main...

Is there an Intrahousehold Flypaper Effect? : Evidence from a School Feeding Program
Provedor de dados: 31
Autores: Jacoby,   Hanan G.
Are public transfers targeted toward children largely neutralized by the household, as the theory of altruism implies, or is there an intrahousehold “flypaper effect” whereby such transfers “stick” to the child? This paper studies the impact of a school feeding program on child caloric intake in the Philippines. Because children are interviewed on school days and nonschool days, and because some schools offer a feeding program and others do not, the dietary impact of the program is identified under mild restrictions. The empirical results confirm an intrahousehold flypaper effect; indeed, they indicate virtually no intrahousehold reallocation of calories in response to the feeding program. In poorer households, however, children’s gains from the program...

Autores: Nakuja,   Tekuni; Akhand,   M.; Hobbs,   Jill E.; Kerr,   William A.
The FSMA appears to be a major undertaking with a very large responsibility placed on the FDA. It would seem that bottlenecks to exporting are bound to appear which will be very frustrating for Canadian firms. It is important for Canadian firms and Canadian policy makers to work hard to ensure that temporary bottlenecks do not become permanent inhibitors of trade. The Canadian government needs to understand industry concerns and use any mechanisms – including those in the NAFTA – to initiate consultations with the US. Given the likely lags in implementation, North American food markets are likely to exhibit considerable disequilibrium over the near term. Trade flows will be affected. As the implementation programs of the FSMA become more transparent, more...

Did the WTO Play a Role in the Food Crisis?
Provedor de dados: 31
Autores: Meilke,   Karl D.
When high prices or natural calamities result in starvation and political unrest in the developing world emergency food aid is the best short run response. However, over a longer time frame it is important to have in place international rules that allow the market to function to help alleviate food shortages rather than making them worse. Given Canada’s trading position we have a huge stake in getting these rules right. Although the future of the Doha Round is unclear there is still time to make a start on developing better rules for export prohibitions, restrictions and export taxes that would serve the world better in times of shortage. A first step would be effective disciplines on the use of export taxes, and export restrictions and embargo’s.

Autores: Bukeviciute,   Lina; Dierx,   Adriaan; Ilzkovitz,   Fabienne; Roty,   Guillaume.
Agricultural commodities and consumer food prices have experienced strong variations over the last 2 years, both upwards and downwards. This increased volatility, combined with long-term prospects of rising food prices, highlights the necessity to increase the efficiency of the food supply chain to ensure consumer food prices reflect the evolution of inputs prices. This paper aims at better understanding price transmission  mechanisms along the chain across European Union Member States. Significant differences across Member States in magnitude of pass-through of agricultural commodity prices variations to consumer prices, as well as price transmission asymmetries, suggest potential market fragmentation within the EU.

USDA defines beginning farmers and ranchers as those who have operated a farm or ranch for 10 years or less either as a sole operator or with others who have operated a farm or ranch for 10 years or less. Beginning farmers tend to be younger than established farmers and to operate smaller farms or ranches, some of which may provide no annual production. Beginning farmers often face obstacles getting started, including high startup costs and limited availability of land. USDA—through the Farm Service Agency and the Natural Resources Conservation Service—provides loans and conservation assistance to beginning farmers and ranchers.

A Dietary Assessment of the U.S. Food Supply: Comparing Per Capita Food Consumption with Food Guide Pyramid Serving Recommendations
Provedor de dados: 31
Autores: Kantor,   Linda Scott.
Most American diets do not meet Federal Food Guide Pyramid dietary recommendations. On average, people consume too many servings of added fats and sugars and too few servings of fruits, vegetables, dairy products, lean meats, and foods made from whole grains compared with a reference set of Food Guide Pyramid serving recommendations appropriate to the age and gender composition of the U.S. population. In addition, while the healthfulness of diets has improved over time, the pace of improvement has been uneven. For example, while Americans consumed record amounts of fruits and vegetables in 1996, consumption of caloric sweeteners also reached a 27-year high. This report is the first dietary assessment to use ERSís time-series food supply data to compare...

A flexible, full rank two model of food consumption that is globally consistent with economic theory, aggregates across income, demographic variables, and variations in micro demand parameters, and accommodates tradeoffs between tastes and nutrition is derived.  The econometric demand model is estimated with per capita U.S. consumption of 21 foods on the time period 1919-1994, excluding the World War II years 1942-1946.  An approach for inferring the percentage of nutrients available from individual commodities in the U.S. food supply is derived and implemented empirically on the time period 1949-1995 for the nutrients energy, protein, total fat, carbohydrates, and cholesterol.  The two sets of model results are combined to generate time paths for income...

Local Food Marketing: Factors for Growth of Small Agri‐food Businesses in the UK
Provedor de dados: 31
Autores: Hingley,   Martin; Boone,   Julie; Haley,   Simon.
This study aims to understand local food and explore the barriers to development for small innovative food businesses. Research was conducted through depth interviews and a survey in North‐West England. Results indicate that small business success can be subjective and performance dependent on business aims. Identified were issues concerning access to finance, burden of regulations and the need for support from industry networks and government. Lack of an official and recognised definition of the term “local food” had implications for marketing strategy. Small businesses recognise that customers are increasingly concerned with food provenance and traceability, but that they and their representative associations need to do more to make these links.

Food choice and health across the life course: A qualitative study examining food choice in older Irish adults
Provedor de dados: 31
Autores: Delaney,   Mary; McCarthy,   Mary.
Ireland has experienced much economic and social change in recent times along with rising levels of overweight. Two-thirds of adults are now overweight or obese. Excess weight is a major risk for chronic disease for all ages which heralds a great societal burden and presents challenges and opportunities for the food industry. Individual food choice is an important and complex factor to be understood in order for food manufacturers to enable healthy choices. It can be understood as a process in which patterns arise and change over time, influenced by a range of personal factors and environmental influences. This study aimed to gain insight into the key contextual influences on food choice patterns in older Irish adults of varied health status who have lived...

Autores: Di Giuseppe,   Stefania.
In this paper a method to examine how households make their food choice considering micronutrients through utility theory is applied. The findings support the argument that nutrients play an important roles in the demand for food. The method is illustrated using the raw data EIH 2000/2001 (Enquesta Integrata de Hogares) for a set of different food groups.

Traceability and Assurance Protocols in the Global Food System
Provedor de dados: 31
Autores: Jones,   Eluned; Poghosyan,   Arsen; Gonzalez-Diaz,   Francisco; Bolotova,   Yuliya.
In the 21st century, the food supply chain has become a complex, interconnected system with strategies that are aimed at creating improved products to satisfy consumers' demand for safer foods. To stay competitive and ensure consumer confidence, agribusiness firms develop and implement strategies that take into account not only traditional economic factors driving the food demand, but also issues such as food safety and quality. Traceability and assurance protocols help agribusiness companies improve and refine their production processes, thus providing better control over, and transparency of, food quality and safety throughout the food supply chain. This paper reports on the empirical results of focus interviews conducted during the 2004 IAMA conference...

Autores: Leat,   Philip M.K.; Lamprinopoulou-Kranis,   Chrysa; Revoredo-Giha,   Cesar; Kupiec-Teahan,   Beata.
This paper examines the influence of agri-food supply chains on the sustainability-related activities and decisions of Scottish farmers, as well as the treatment of sustainability issues by food processors and retailers themselves. It is based on 8 whole chain case studies covering some of Scotland‘s major agricultural products. The cases identify differing levels of understanding and activities related to sustainability, but widespread acknowledgement that sustainability involves the development of chains within which all parties can achieve acceptable profits. Indeed, collaborative supply chains, which seek improved economic performance, frequently assist environmental and social sustainability. The main drivers of sustainability are found to be the cost...

This report examines major trends in the amount of food available for consumption in the United States between 1970 and 2005 using data from the ERS Food Availability (Per Capita) Data System. The report also estimates whether Americans are meeting Federal dietary recommendations for each of the major food groups by comparing the data with dietary recommendations in the 2005 Dietary Guidelines for Americans and the MyPyramid Food Guidance System. Findings show that Americans do not meet the Federal dietary recommendations. In order to meet them, Americans would need to substantially lower their intake of added fats, refined grains, and added sugars and sweeteners and increase their consumption of fruits, vegetables, whole grains, and lowfat milk and milk...

Autores: Clark,   J. Stephen; Thibodeau,   David R.; Grant,   K. Gary; Prochazkova,   Katerina.
This study analyzed the impact of PVYn and potato wart disease outbreaks in PEI on the potato industry. These disease outbreaks resulted in the loss of the US seed export market to PEI producers. The effects of the disease outbreaks were mitigated through value-added processing. Price premiums for processed potatoes allowed PEI potato producers to abandon seed exports without incurring losses. Evidence is presented to suggest that other countries have also used this approach when export restrictions were placed on domestic agricultural industries. Policy response to the two disease outbreaks include: i) development of a zones policy that helped to reopen markets into the US; and ii) financial compensation to producers above the minimum levels required...

Moving Toward the Food Guide Pyramid: Implications for U.S. Agriculture
Provedor de dados: 31
Autores: Young,   C. Edwin; Kantor,   Linda Scott.
Recent studies show that average diets differ considerably from Food Guide Pyramid recommendations. The gap between current consumption and recommendations is particularly large for caloric sweeteners, fats and oils, fruits, and certain vegetables, notably dark-green leafy and deep-yellow vegetables, and dry beans, peas, and lentils. The change in food consumption needed to meet Food Guide Pyramid serving recommendations will result in adjustments in U.S. agricultural production, trade, nonfood uses, and prices. The net adjustment in crop acreage is projected to be relatively small, about 2 percent of total cropland in 1991-95. However, this small net adjustment masks larger anticipated changes for some sectors, particularly sweeteners, fats and oils, and...

Commercialization of Food Consumption in Rural China
Provedor de dados: 31
Autores: Gale,   H. Frederick, Jr.; Tang,   Ping; Bai,   Xianhong; Xu,   Huijun.
Rural households in China have traditionally consumed food mostly grown on their own farms. While they continue to rely on self-produced grains, vegetables, meats, and eggs for a large portion of their diet, rural households are now purchasing more of their food as they enter the mainstream of the Chinese economy. Cash purchases of food by rural Chinese households increased 7.4 percent per year from 1994 to 2003. Consumption has shifted from self-produced to purchased food at a rate faster than can be explained by income growth or changes in other household characteristics. The move away from self-produced food is associated with lower consumption of staple grains, the most important self produced food in rural Chinese diets. Food consumed away from home...

IS A PUBLIC REGULATION OF FOOD PRICE VOLATILITY FEASIBLE IN AFRICA? AN ARCH APPROACH IN KENYA
Provedor de dados: 31
Autores: Maitre d'Hotel,   Elodie; le Cotty,   Tristan; Jayne,   Thomas S.
The 2007-2008 food crisis and current food price swings led economists to re-evaluate the potential for policy instruments to manage food price volatility. Many developing countries recently pursued price regulation policies, but the difficulties of these policies in promoting price stability is not fully understood. In particular, the ability of a stabilization policy to lower food price volatility does not depend on the nature of the policy instrument only, but also on the institutional conditions of its implementation. Kenya is a particularly interesting case as it is characterized by a rather long tradition of public intervention, and by the persistence of highly volatile prices. The consistency of the policy use appears to be key factor influencing...

In this study we have attempted, in collaboration with an agrifood company, to compare and contrast the responses of consumers and professionals to the same set of situations raising ethical questions, in order to highlight the differences and the similarities of viewpoint between these two groups of stakeholders. In order to do this, we constructed multi-stakeholder scenarios comprising a description of the situation and the various possible approaches to managing the situation. We constructed two scenarios, dealing with the origin of the gelatin used in the company's products and the company's product information on livestock feed (GMO). This allowed us to: - study the extent of the professionals' ethical perceptions and the possible compromises between...

Post-Moratorium EU Regulation of Genetically Modified Products: Triffid Flax
Provedor de dados: 31

The regulatory regime for contamination permits the imposition of import bans with neither a scientific justification nor a risk assessment. No scientific assessment of Triffid flax was done prior to the import ban. The import regime put in place to deal with the contamination of flax with the GM-flax CDC Triffid provides no rationale for the thresholds of safety established for the testing regime. The EU is consistently pushing for commercial, economic and social considerations to be included, along with science, in decision-making. Such considerations are often perceived as avenues for economic protection to creep into EU decision-making. Such considerations can, however, cut both ways. The Canada-EU testing regime for Triffid makes provision for, but...

Autores: van Moorsel,   Daryl; Cranfield,   John A.L.; Sparling,   David.
Advancement in biotechnology requires continued innovative activity by firms.  To grow, biotechnology firms must understand the factors affecting their innovative activity.  Such understanding also informs policy makers, and supports the development of policies promoting one's biotechnology sector.  This study explores factors which determine innovative activity within the Canadian biotechnology industry.  Innovative activity is measured as the natural log of the number of products/processes a firm has at different stages of the innovation spectrum.  A model is developed to regress this measure on several determinants of innovation.  Significant drivers of innovation include: collaborative arrangements, transfer of intellectual property, firm size and age,...

Changing Factor Income Shares in Agri-Food Industries
Provedor de dados: 31
Autores: Konduru,   Srinivasa; Bjornson,   Bruce.
A concern in the political economy is how national income is shared between labor and capital.  This study evaluates long-term changes in factor income shares in three agri-food industries, their attribution to the level of factor usage or to factor compensation rates, and relation to changes in capital intensity and factor productivity.  We find long-term stability in the profit and labor shares of farm income, decline, in the profit share of agricultural serviced industry income, and increase in the profit share of food manufacturing income due to fewer productivity improvements being passed on to wage increases.

HOUSEHOLD FOOD CHOICE IN FOUR FOOD CATEGORIES: HEALTHY OR UNHEALTHY?
Provedor de dados: 31
Autores: Binkley,   James K.; Golub,   Alla A.
The interest of this study is the tradeoff between nutrition and taste in consumer food choice.  We examine choice between more and less healthy versions of particular foods within four important grocery categories: breakfast cereal, milk, bread, and soft drinks.  Within a category, products do not greatly differ in terms of cost and convenience, and nutritional differences are easily determined.  Consumers are less likely to choose unhealthy foods due to cost or convenience advantages, or through ignorance. This makes the choice between taste and nutrition more apparent. We use annual expenditure data reported by a large sample of households participating in the AC Nielsen Homescan data system.  For each of the food categories we develop a measure of...

DEMAND FOR FOOD QUANTITY AND QUALITY IN CHINA
Provedor de dados: 31
Autores: Gale,   H. Frederick, Jr.; Huang,   Kuo S.
As their incomes rise, Chinese consumers are changing their diets and demanding greater quality, convenience, and safety in food. Food expenditures grow faster than quantities purchased as income rises, suggesting that consumers with higher incomes purchase more expensive foods. The top-earning Chinese households appear to have reached a point where the income elasticity of demand for quantity of most foods is near zero. China’s food market is becoming segmented. The demand for quality by high-income households has fueled recent growth in modern food retail and sales of premium-priced food and beverage products. Food expenditures and incomes have grown much more slowly for rural and low-income urban households.

In this study, a Structural Vector Autoregression model (SVAR) is employed to decompose how supply/demand structural shocks affect food and fuel prices within fuel and corn markets. Results indicate that the relative importance of each structural shock in explaining the variation of corn prices is different. Our findings support the hypothesis that corn prices increase as a response to those positive demand shocks in the short run, while in the long run, global competitive agricultural commodities markets as well as positive supply shocks respond to commodity price shocks, restoring prices to its long-run trends. In conclusion, fundamental market forces of demand and supply as well as real economic aggregated demand shocks were the main contributors of the...

Changing consumer and market demands is an important driver behind the challenges and opportunities that are facing the agriculture and agri-food sector in Canada and that will influence the sector's profitability and competitiveness in the future. It is therefore important to understand developments in the consumer demand for agriculture and agri-food products. The report provides updated demand elasticities for fourteen food groups in Canada. The estimates are useful for conducting analysis of the changing structure of the agriculture and agri-food sector and can help quantify the impacts that changes in economic variables and policies that impact those economic variables might have.

The economy of Dominica faces a unique set of challenges.  As with many other Caribbean nations, Dominica has historically been dependent upon agriculture.  Over the past several hundred years, the island's economy has been largely supported through the concentrated mono-cropping of a variety of export-oriented crops including coffee, limes, vanilla, and bananas (FAVACA, 2008).  Today, approximately 45% of Dominica's labor force is employed in the agricultural sector (FAVACA, 2008).  While neighboring countries have economically benefited from tourism, due to its lack of white sand beaches, Dominica is not a typical tourist destination.  Taking advantage of its landscape, rainforests, and diversity of natural wildlife, in an effort to diversify its economy...

Origin- claimed food products mainstream gives diverse features over the world. The food labelling practices based on origin or provenance are frequently developed as a reaction to global trading system: private and NGO's initiatives (Fair Trade), enterprises in UK (Local Foods) and USA (Food Alliance), medals for winners in local exhibitions awards, or public regulation in European Union (PDO, PGI, Organic Farming). These practices claim at reaching consumer expectations. For a consumer who is frequently being uprooted and is stressed by his/her urban environment, the emotional content of where one's food is produced is greater than ever. With a longing for one's home, the consumer becomes an identity seeker. Origin, organic or fair trade food products...

Analysis of Country of Origin Labeling for Food Products in Taiwan Using Auction Experiment with Tasting
Provedor de dados: 31
Autores: Chern,   Wen S.; Lin,   Huei-Ching.
This study attempts to evaluate the economic benefits of the country of origin labeling (COOL) in Taiwan.  A Vickrey second-price sealed-bid auction was conducted to estimate the consumer’s willingness to pay for Taiwan products vs. those from China and Vietnam. Our experiment was designed to investigate the impacts of product tasting on bidding behavior. The regression results show that tasting raised bids for Taiwan and China teas, but lowered bids for Vietnam tea. The econometric results show very high premiums for Taiwan products. Taiwanese consumers and food producers stand to benefit greatly with COOL.

Over the last years, food safety, health and environmental issues are a few among many other reasons that force consumers to adopt new innovative food products – organic, private label, genetically modified and functional – as part of their consumption. This spectacular shift of the consumption forwards “innovative” food products attracts the interest of the analyst as it can shed new light on consumer’s behaviour and on modeling and understanding better his long-term behaviour. Thus, this study attempts to investigate the factors that influence consumer’s decision in purchasing either traditional or new innovative products and to what extend this shift between those two groups of products is related to pre-defined elements. This is achieved by employing...

Discussion: Economic Sustainability of Rural Areas
Provedor de dados: 31
Autores: Constance,   Douglas H.
The three articles in this invited paper session examine value-added strategies related to agriculture and food at the state and federal level designed to enhance rural development.  Two of the papers dealt with the GO TEXAN program and the other with organic agriculture. All three papers were well written and interesting, but all three also shed light on the problem of using classical economic theory to interpret differentiated agriculture and food products as opposed to undifferentiated commodities.

FINANCIAL ANALYSIS OF SMALL FOOD MANUFACTURING AND RETAILING BUSINESSES
Provedor de dados: 31
Autores: Gustafson,   Cole R.
The 1998 Survey of Small Business Finances provides robust information on the financing of small businesses including an overview of their firm's organization, financial characteristics, and credit use.  Information from the survey is used in this study to compare the financial characteristics of food manufacturing and retailing small businesses.  On average, both food manufacturing and food retailing small businesses had positive financial characteristics.  Although they were only marginally profitable and liquid, they were highly solvent.  Accounts receivable and inventory comprise nearly half of food manufacturers' total assets and a third of food retailers' assets.  By most financial measures, food retailers were statistically smaller than food...

Science in Sanitary and Phytosanitary Dispute Resolution
Provedor de dados: 31
Autores: Powell,   Mark R.
The World Trade Organization Sanitary and Phytosanitary Agreement (SPS Agreement) relies heavily on science and expert organizations to avoid and resolve trade disputes over measures enacted under the rationale of food safety or plant and animal health protection. However, the state of science for sanitary and phytosanitary risk analysis is highly uncertain, and the SPS Agreement leaves many science policy issues unsettled. The international agencies charged under the SPS Agreement with harmonizing standards and forging international scientific consensus face a daunting and politically-charged task. Two case studies are briefly developed. In the first case, the international scientific consensus strongly supports the U.S. challenge of the European Union's...

The Asymmetric Effect of Dietary Knowledge on Nutrient Intake In China: Implications for Dietary Education Programs
Provedor de dados: 31
Autores: Shimokawa,   Satoru.
This paper demonstrates that dietary knowledge can influence nutrient intake differently depending on whether expected food availability is increasing or decreasing. Using data from China, we find that overall dietary knowledge has larger and more statistically significant effects on total calorie intake and the intake of three macro nutrients (carbohydrate, fat, and protein) when expected food availability increases than when it decreases. Without distinguishing the direction of changes in expected food availability, most of the corresponding effects become smaller and statistically insignificant. Thus, the effect of dietary knowledge on nutrient intake might have been underestimated in previous studies. We discuss the implications of these findings for...

Process versus product: which determines consumer demand for genetically modified apples?
Provedor de dados: 31
Autores: Kaye-Blake,   William; Bicknell,   Kathryn; Saunders,   Caroline M.
One debate in the literature regarding consumers’ reactions to genetically modified food (GMF) centres on whether consumers react to the process of gene technology or to the specific GMF products. Results from a choice experiment survey in New Zealand indicate that consumers are heterogeneous with regard to GMF and that some modifications are viewed more positively than others. These findings suggest that for some consumers the process of gene technology is the decisive factor in evaluatingGMF, while for others the different potential GMF products are valued according to their enhanced attributes.

There is a growing consumer segment demanding healthy foods and diets, health and nutrition messages can expand food demand, and governments in the U.S. and EU, faced with increasing obesity and associated health outcomes, want consumers to have reliable information to choose healthy diets. California commodity organizations, charged with expanding the demand for almonds, avocados, strawberries and walnuts, are funding health and nutrition research as a means to discover a unique selling proposition for each product. Research and promotion effects are attracting interest by other commodity groups. Policy and regulatory issues abound.

On the Distribution of Net Benefits from Sustainability Initiatives in Agri-Food Supply Chains
Provedor de dados: 31
Autores: Ross,   Brent; Amanor-Boadu,   Vincent; Ross,   Kara L.
Sustainability initiatives are frequently imposed on upstream supply chain members by their more powerful downstream partners.  This paper assesses the challenges of estimating costs and benefits for participants and the difficulties associated with identifying their locations and effects in the supply chain.  The paper argues that the success and endurance of agri-food supply chains that purport to pursue sustainability objectives depend critically on the distribution of the associated costs and benefits.  It calls on supply chain leaders to give careful consideration to the distribution of net benefits across the chain to ensure that opportunism and moral hazard are minimized.

The Effect of Innovation on Agricultural and Agri-food Exports in OECD Countries
Provedor de dados: 31
Autores: Ghazalian,   Pascal L.; Furtan,   William Hartley.
This paper investigates the effect of innovation on primary agricultural and processed food product exports among the Organization for Economic Cooperation and Development (OECD) countries.  A theoretical gravity equation that accounts for innovation is derived.  The empirical exercise uses panel data sets covering 21 OECD countries for the period 1990-2003.  The R&amp;D capital stock is employed as a tangible way of measuring innovation.  Empirical results show that R&amp;D has enhanced exports in the primary agricultural sector.  Meanwhile, the market expansion effect of R&amp;D appears to be more than offset by the market power effect in the food processing sector, resulting in a decrease in exports.  Also, evidence was found of a positive vertical...

Autores: Leat,   Philip M.K.; Lamprinopoulou-Kranis,   Chrysa; Revoredo-Giha,   Cesar; Kupiec-Teahan,   Beata.
This paper examines the influence of agri-food supply chains on the sustainability-related activities and decisions of Scottish farmers, as well as the treatment of sustainability issues by food processors and retailers themselves. It is based on 8 whole chain case studies covering some of Scotland’s major agricultural products. The cases identify differing levels of understanding and activities related to sustainability, but widespread acknowledgement that sustainability involves the development of chains within which all parties can achieve acceptable profits. Indeed, collaborative supply chains, which seek improved economic performance, frequently assist environmental and social sustainability. The main drivers of sustainability are found to be the cost...

Food Reserve Stocks and Critical Food Shortages - a Proposal Based on the Needs of Sub-Saharan Africa
Provedor de dados: 31
Autores: Lind,   Kim Martin.
This working paper examines the food security policy, where food security means ensuring an adequate supply of food for hungry people. In particular, the recommendations of FAO are being used as a measuring rod against which food security policies are assessed. By means of FAO's database a statistical analysis of all Sub-Saharan Africa countries with respect to measuring the incidence and severity of critical food shortages are carried out. Stock policies seem to have been the answer when issues of ensuring adequate supplies have surfaced. In the paper, an estimate of the costs of keeping stocks is provided, and the costs are quite staggering. Based on the statistical analysis an estimate of the number and volume of acute food shortages per year in...

GRAZING, GOODS AND GIRTH: DETERMINANTS AND EFFECTS
Provedor de dados: 31
Autores: Hamermesh,   Daniel S.
Using the 2006-07 American Time Use Survey and its Eating and Health Module, I show that over half of adult Americans report grazing (secondary eating/drinking) on a typical day, with grazing time almost equaling primary eating/drinking time. An economic model predicts that higher wage rates (price of time) will lead to substitution of grazing for primary eating/drinking, especially by raising the number of grazing incidents relative to meals. This prediction is confirmed in these data. Eating meals more frequently is associated with lower BMI and better self-reported health, as is grazing more frequently. Food purchases are positively related to time spent eating—substitution of goods for time is difficult—but are lower when eating time is spread over...

Sources of human non-typhoid salmonellosis: a review
Provedor de dados: 89
Autores: Freitas Neto,OC de; Penha Filho,RAC; Barrow,P; Berchieri Junior,A.
Salmonellosis is a worldwide disease caused by bacteria of the genus Salmonella. Currently, there are over 2,500 identified serovars of Salmonella. A reduced number of these serovars, about eighty, are implicated in most animals and human diseases. Most cases of salmonellosis in humans are associated with the consumption of contaminated food products such as beef, pork, poultry meat, eggs, vegetables, juices and other kind of foods. It may also be associated with the contact between humans and infected pet animals. Therefore, the chain of human salmonellosis is very complex and in most cases the origin of the infection is difficult to establish. The use of antimicrobial agents to treat and to prevent bacterial infections in humans and animals, as well as...

Nutritional ecology of blowflies (Diptera, Calliphoridae): estimates of critical larval weight for pupation on two different
Provedor de dados: 92
Autores: Ribeiro,Cássio da Silva; Von Zuben,Cláudio José.
Under natural environmental conditions, blowflies utilize discrete and ephemeral feeding resources such as decaying carcasses. Competition for food on such feeding substrates is usually very severe, and only the individuals that are capable of attaining the critical larval weight for pupation will be able to survive. This critical weight is hitherto unknown for several blowfly species; therefore, the current work is aimed at obtaining such a critical value for four blowfly species of the genera Chrysomya and Lucilia, deploying two types of feeding substrate, namely, artificial diet and macerated bovine meat. On the whole, the critical weights ranged from 30 to 35 mg. The lowest larval weight which permitted pupation was 30.0 mg for Chrysomya megacephala...

To determine the available phosphorus requirement of pejerrey fish, four semi-purified diets were formulated to contain increasing available phosphorus levels (0.90, 2.7, 5.7 and 8.3 g/kg). Each diet was assigned to groups of 10 fish with average weight of 1.26±0.17 g, distributed into a completely randomized design with four treatments and four replications. Fish were fed at a rate of 10% total biomass four times a day for 60 days. The parameters productive performance, body chemical composition and mineral composition of bones and scales were evaluated. The best productive performance of fingerlings was obtained with the diet containing 4.3 g/kg available phosphorus. The average level of 6.3 g/kg available phosphorus promotes better mineralization of...

ABSTRACT Seventy-two barrows were used to evaluate the effects of the use of soy protein concentrate (SPC) in diets of post-weaning piglets on their performance, intestinal histomorphometry, and blood parameters. Piglets were weaned at 21 days of age and distributed in a randomized-block experimental design with four treatments (0, 3, 6, and 9% SPC), six replications, and three piglets per replication. Diets were formulated to meet the requirement of the piglets according to phases of 21 to 32, 33 to 42, and 43 to 66 days of age. Both feed and water were provided ad libitum during the entire experiment. The feed of the phase of 43 to 66 days was based on corn and soybean meal. In the period between 21 and 32 days of age, the use of SPC in the diet did not...

Transfer of toxic substances from feed to food
Provedor de dados: 96
Autores: Kan,Cornelis Adriaan.
The title may raise questions about definitions of the terms used. The more obvious ones are: 1) What is transfer? 2) How to define toxic; and 3) How to define feed or food. A more underlying question is how to measure the substances we are interested in. The (often) chemical methods used, are not always sensitive or specific enough. Sometimes, biologically based methods are used which detect a biological response, but seldom identify the compound responsible for that. Transfer is often not quantified in absolute terms but expressed in concentrations in feed and food. Mass balance between intake and excretion are quite rare as a steady state situation of residues in the animal is sometimes not obtained. Toxicity is mostly dependent on the concentration of...

Autores: Rossi, Gabriel Augusto Marques; Lemos, Paulo de Paula Lopes.
The market for organic products is increasing globally, seeking to fulfill the needs and expectations of consumers who believe it’s a healthier food. There are many controversies found in studies that assess primarily the physical-chemical, microbiological and the presence of this type of food of animal origin. This review aimed to evaluate the main differences between animal foods such as meat, milk, honey, eggs and fish produced in organic systems compared to those produced in conventional systems. The main differences are related to the physical-chemical food and no relevant differences were found between the possible presence of chemical or biological hazards in food of animal origin.

In order to analyse the diet of Schizodon intermedius Garavello &amp;amp; Britski, 1990, captures were made every season during the period of April/1990 to February/1991, using gillnets of different mesh size at Sertanópolis, a region of Paraná State. An analysis of stomach fullness degree was made upon 76 individuals (including young ones). A sample of 20 adult specimens was chose to compare the morphology of the digestive tract with the diet found. It was concluded that S. intermedius is a grazer herbivore whose principal diet consists of leaves and stalks of two monocotyledonous plants: Poaceae and/or Cyperaceae. This species shows quanlitative, but not qualitative feeding seasonal variations. It was verified that intestinal quotient of the species is X...

Abstract: Bioaccumulation of heavy metals such as cadmium has been a major concern in scientific communities and international food organizations, given the great toxicological risk to the consumer, and in many places there is no detailed record of its actual content. In this way, the need arises to carry out a study and registration of the concentration of this metal in products such as table chocolate, of great consumption at regional and national level. Likewise, we seek to have effective quantification tools and a reliable and affordable method to achieve the aim of this research. In this research, Cadmium content in powdered and granulated table chocolate was determined, elaborated and commercialized in the municipality of Chiquinquira,...

Occurrence and molecular characterization of different virulence-associated genes of Cronobacter sakazakii isolates from some foods and dust samples
Provedor de dados: 65
Autores: Demirci,Ülkü; Tekiner,İsmail Hakkı; Çakmak,Burcu; Özpınar,Haydar.
ABSTRACT:  Among the Cronobacter genus, Cronobacter sakazakii is the most common species posing a severe health risk for newborns, infants and children. Some infant formulas, cereal-based foods, and food production environments may be the potential reservoirs of C. sakazakii. This pathogen possesses different virulence factors encoded by different virulence genes. Therefore, characterizing these genes is important for distinguishing pathogenic strains from nonpathogenic ones. The objective of this study was to characterize some virulence genes [OmpA, OmpX, zpx, and Cpa] by real-time polymerase chain reaction (PCR) in C. sakazakii isolates from a total of 120 samples (20 each of milk powder, starch, rice flour, semolina, infant formula and dust samples from...
