A Battle of Taste and Environmental Convictions for Ecolabeled Seafood: A Contingent Ranking Experiment AgEcon
Johnston, Robert J.; Roheim, Cathy A..
Consumers face pressure from environmental groups to modify their seafood purchase decisions based on concerns about fisheries' production practices. Existing research provides little information indicating whether seafood consumers are willing to change purchasing behavior based on a product's environmental attributes, to the exclusion of other attributes. We describe a contingent ranking experiment addressing preferences for fresh seafood, allowing for choices among different species, some displaying an ecolabel. Results suggest consumers consider overfishing sufficiently important to contemplate changing the species of fish they buy; however, they are unwilling to choose a less-favored species based solely on the presence of an ecolabel.

A CONJOINT ANALYSIS OF NEW FOOD PRODUCTS PROCESSED FROM UNDERUTILIZED SMALL CRAWFISH AgEcon
Harrison, R. Wes; Ozayan, Aylin; Meyers, Samuel P..
Attributes for two value-added seafood products derived from underutilized crawfish are analyzed using conjoint data from seafood restaurants in the southern region of the United States. Preferences for the products' form, price, and flavor attributes were tested. Statistical tests revealed that the attribute interactions were not significant, and part-worth utilities for all main effects were estimated using an additive preference model. Results indicate that the new crawfish products should be marketed as a high-quality fresh soup base or seafood stuffing, priced between 30% and 50% of the cost of fresh crawfish tail meat.

In'T; Leclercq, A.; Baker-austin, C..
Globally, vibrios represent an important and well-established group of bacterial foodborne pathogens. The European Commission (EC) mandated the Comite de European Normalisation (CEN) to undertake work to provide validation data for 15 methods in microbiology to support EC legislation. As part of this mandated work programme, merging of ISO/TS 21872–1:2007, which specifies a horizontal method for the detection of V. parahaemolyticus and V. cholerae, and ISO/TS 21872–2:2007, a similar horizontal method for the detection of potentially pathogenic vibrios other than V. cholerae and V. parahaemolyticus) was proposed. Both parts of ISO/TS 21872 utilized classical culture-based isolation techniques coupled with biochemical confirmation steps. The work also...

A Review of FDA Imports Refusals - US Seafood Trade 2000-2010 AgEcon
Anders, Sven M.; Westra, Sabrina.
The United States is the third largest consumer of seafood products in the world. The percentage of imported seafood consumed in the U.S. has steadily increased from 66% in 1999 to over 84% in 2009 (NOAA, 2010). Food safety, especially of imported foods and products from developing countries, has raised increasing concerns among American consumers and policy makers. Accordingly, the Food and Drug Administration’s (FDA) (Ababouch et al. 2000) border inspection system is considered critical for ensuring the safety of domestic seafood consumers. However, the potential non-tariff barrier to trade posed by FDA regulations, especially for many developing country exporters have been frequently cited in the literature. This paper investigates trends and patterns...

Analysis of the Preferences for a New Convenient Seafood Product: Empirical Application for Spain and Norway AgEcon
Dopico, Domingo Calvo; Olsen, Svein Ottar; Tudoran, Alina.
Fish and seafood products represent a very healthy food, low in saturated fats and offer an excellent source of protein essential for our health. However, very often, consumer behaviour would seem to infer that seafood products do not rank particularly highly in terms of preference, this being due to the perception of various physical and psychological costs, which represent barriers to consumption. Consequently, there is an opportunity to develop new tailor-made seafood products more adapted to recent demand. The aim of this study is to analyse the overall preference of young consumers for such a new seafood product. The experiments were carried out in two European countries: Spain and Norway, with samples of 349 and 296 young people respectively. The...

Characterisation of the spoilage microbiota in raw salmon (Salmo salar) steaks stored under vacuum or modified atmosphere packaging combining conventional methods and PCR–TTGE ArchiMer
Mace, Sabrina; Cornet, Josiane; Chevalier, Frederique; Cardinal, Mireille; Pilet, Marie-france; Dousset, Xavier; Joffraud, Jean-jacques.
In order to characterise the spoilage related to microbiota of raw salmon, a combination of culture-dependent and -independent methods, including PCR–TTGE, was used to analyse 3 raw salmon batches stored for 3 days at chilled temperature in modified atmosphere packaging (MAP) (50% CO2/50% N2) or under vacuum. Sensory evaluation, microbiological enumeration and chemical analysis were performed after 3, 7 and 10 days of storage. At the onset of spoilage, 65 bacterial isolates were picked from the plates. Thus, 13 different genera or species were identified by phenotypic and molecular tests: Serratia spp., Photobacterium phosphoreum, Yersinia intermedia, Hafnia alvei, Buttiauxella gaviniae, Pseudomonas sp., Carnobacterium maltaromaticum, Carnobacterium...

An international outbreak linked to oyster consumption involving a group of over 200 people in Italy and 127 total subjects in 13 smaller clusters in France was analyzed using epidemiological and clinical data and shellfish samples. Environmental information from the oyster-producing area, located in a lagoon in southern France, was collected to investigate the possible events leading to the contamination. Virologic analyses were conducted by reverse transcription-PCR (RT-PCR) using the same primer sets for both clinical and environmental samples. After sequencing, the data were analyzed through the database operated by the scientific network FoodBorne Viruses in Europe. The existence of an international collaboration between laboratories was critical to...

Development of genomic probes for detection of hepatitis A virus and enteroviruses in shellfish ArchiMer
Apaire, M; Leguyader, F; Besse, B; Billaudel, S.
The development of molecular biology techniques has modified research procedures for certain viruses, particularly hepatitis A virus (HAV) and enteroviruses. Accordingly, we designed cDNA and RNA genomic probes to detect viruses in shellfish in the environment. Better sensitivity was noted with RNA than cDNA probes: only 17/83 shellfish samples were positive with HAV and enterovirus DNA probes, where as 42/83 were positive with HAV and enterovirus RNA probes.

Effect of vacuum and modified atmosphere packaging on the microbiological, chemical and sensory properties of tropical red drum ( Sciaenops ocellatus ) fillets stored at 4 °C ArchiMer
Silbande, Adele; Adenet, Sandra; Chopin, Christine; Cornet, Josiane; Smith-ravin, Juliette; Rochefort, Katia; Leroi, Francoise.
Aims The effect of vacuum (VP – 4 °C) and CO2/N2–atmosphere (MAP – 4 °C) packaging on the quality of red drum fillets compared with whole gutted iced fish was investigated. Methods and results A metagenomic approach, bacterial enumeration and isolation, biochemical and sensory analyses were carried out. The organoleptic rejection of whole fish was observed at day 15 whereas VP and MAP fillets appeared unacceptable only after 29 days. At these dates, total mesophilic counts reached 107–108 CFU g− 1. According to Illumina MiSeq sequencing, Arthrobacter, Chryseobacterium, Brevibacterium, Staphylococcus and Kocuria were the main genera of the fresh red drum fillets. At the sensory rejection time, lactic acid bacteria (LAB), particularly Carnobacterium sp.,...

Effects of Food Safety Standards on Seafood Exports to US, EU and Japan AgEcon
Nguyen, Anh Van Thi; Wilson, Norbert L.W..
Estimating the panel gravity model with bilateral pair and country-by-time fixed-effects separately for each seafood product, we found that food safety regulations have differential effects across seafood products. In all three industrialized markets, shrimp is most sensitive, while fish is the least sensitive to changing food safety policies. The enforcement of the US HACCP, the EU Minimum Required Performance Level and the Japanese Food Safety Basic Law caused a loss of 90.45%, 99.47%, and 99.97% to shrimp trade in these markets, and a reduction associated with fish trade was 66.71%, 82.83%, and 89.32%.

ESTIMATING THE COST OF FOOD SAFETY REGULATION TO THE NEW ZEALAND SEAFOOD INDUSTRY AgEcon
Cao, Kay; Maurer, Oswin; Scrimgeour, Frank G..
In New Zealand, the Animal Products Act 1999 requires all animal product processing businesses to have a HACCP-based risk management program by the end of 2002. This paper attempts to measure the effects of such regulation on the variable cost of production of the New Zealand seafood industry. Using the framework developed by Antle (2000), a model of quality-adjusted translog cost function is estimated using census of production data from 1929 to 1998. Our results show that variable costs could increase from 2% to 22% or from 2 cents to 19 cents per kilogram.

Fish and fishery products trade in Brazil, 2005 to 2015: A review of available data and trends Scientia Agricola
Barone,Rafael Simões Coelho; Lorenz,Evandro Kleber; Sonoda,Daniel Yokoyama; Cyrino,José Eurico Possebon.
ABSTRACT: Along the last ten years fish and fishery product trade in Brazil has been on a downward trajectory turning a profit of US$ 98.6 million in 2005 into a loss of US$ 1.25 billion by 2014. On the other hand, the country is a leading producer of grains and has the third largest animal feed industry in the world, which has added 5.5 million hectares of freshwater reservoirs and 3.5 million km2 of an exclusive marine economic zone in the same period, a sizable potential for development of the aquaculture industry. This study aims at unveiling strategies for the reduction of the deficit in the Brazilian seafood trade balance, based on critical analysis of the quantitative and qualitative characteristics of imported fishery products. The fish and fishery...
