Brazil is the largest exporter and third largest producer in the chicken meat market. Consequently, it is important to know the relationship between domestic and export prices. Through the Granger causation method and the cointegrating method of Engle and Granger and the Johansen one, this study aims to verify the hypothesis of long-term relationship between both domestic and export prices of chicken meat. The results indicate that prices are cointegrated. The conclusion is that the prices received by the Brazilian producers are possibly sensible to the behavior of world market prices, and therefore they should worried about internal factors which may enlarge differences between both prices.

Controlling Campylabacter in the Chicken Meat Chain: A Cost-Utility Analysis

Mangen, Marie-Josee J.; Havelaar, Arie H.; Nauta, Maarten J.; de Koeijer, Aline A.; de Wit, G. Ardine.

The aim of this study was the estimation of cost-utility of interventions to control Campylobacter contamination of broiler meat. The relative risk, the intervention costs, the disease burden (expressed in DALYs) and the costs-of-illness for the various interventions were necessary inputs for the cost-utility analysis. The cost-utility is expressed in net costs per reduced DALY. The most cost-effective interventions are: reduction of faeces leakage in the slaughter line and decontamination of the carcass by dipping in a chemical solution. Phage therapy might be another cost-effective intervention, depending on assumed costs/chicken. Irradiation is the most efficient intervention, but the least cost-effective.

Transmissão de preços entre mercados regionais de carne de frango no Brasil

Mattos, Leonardo Bornacki de; Lirio, Viviani Silva; Lima, Joao Eustaquio de; Campos, Antonio Carvalho.

Non-negligible transaction costs restrict the transmission of price shock between markets. The aim of this work was to analyze the effects of transaction costs on the spatial integration of the internal market for chicken meat, from 1998 to 2007. The applied methodology was based on the Threshold Cointegration Analysis. The results indicate the presence of significant barriers to the price transmission between the markets, existing probably due to the transaction costs. Prices are not very sensitive to eventual deviations of the long run equilibrium. It could also be noted that a relatively long period is necessary to eliminate price shocks, and the price transmission process is asymmetric.

Impactos da influenza aviária no mercado internacional de carnes

Valente, Luiza Carneiro Mareti; Gomes, Marilia Fernandes Maciel; Campos, Antonio Carvalho.

Animal infectious disease outbreaks as Avian Influenza, Foot and mouth disease and Bovine Spongiform Encephalopathy can influence trade and bring economic consequences to affected countries. For this reason, this work aims to analyze the effects on meat import demand in the years of 1997 and 2003 to 2005, the Avian Influenza outbreaks period. The analytical framework used was panel data econometrics. The results point to a reduction on chicken meat demand in 1997 and increase to the other meats, indicating a possible substitution. From 2003 on, chicken meat demand showed slight increase, as did pig meat, only bovine meat demand showed a reduction. This fact can be explained by a restriction on bovine and chicken supply caused by the imposition of sanitary...

Effect of Origanum syriacum L. Essential Oil on the Storage Stability of Cooked Chicken Meat

Al-Hijazeen,M.

ABSTRACT The effects of the addition of Origanum syriacum L. essential oil (OE) on the lipid and protein oxidation, and sensory attributes of cooked chicken meat were compared with those of synthetic commercial meat preservatives. Ground deboned and skinless chicken breast and thigh meat were distributed according to six treatments: (T1) control (no addition of meat preservative); or the addition of (T2) 100 ppm OE; (T3) 150 ppm OE; (T4) 300 ppm L-ascorbic acid (E-300); (T5) 5 and 14 ppm butylated hydroxyanisoleadded to breast and thigh meat, respectively, (BHA/E-320); and (T6) 150 ppm sodium nitrite (E-250). Meat samples were cooked and analyzed for lipid oxidation (TBARS levels) and protein oxidation (carbonyl levels) on days 0, 4, and 7 days of storage....

Salmonella is traditionally identified by conventional microbiological tests, but the enumeration of this bacterium is not used on a routine basis. Methods such as the most probable number (MPN), which utilize an array of multiple tubes, are time-consuming and expensive, whereas miniaturized most probable number (mMPN) methods, which use microplates, can be adapted for the enumeration of bacteria, saving up time and materials. The aim of the present paper is to assess two mMPN methods for the enumeration of Salmonella sp in artificially-contaminated chicken meat samples. Microplates containing 24 wells (method A) and 96 wells (method B), both with peptone water as pre-enrichment medium and modified semi-solid Rappaport-Vassiliadis (MSRV) as selective...

ABSTRACT The aim of this study was to investigate the presence of shiga toxin-producing Escherichia coli (STEC) and atypical enteropathogenic Escherichia coli (aEPEC) in frozen chicken carcasses sold at stores in southern Brazil. Typical E. coli colonies were enumerated in 246 chicken carcasses, and the presence of stx1, stx2, eae genes was investigated in their rinse liquid and in E. coli strains isolated from those carcasses. Strains of E. coli were also investigated for the presence of bfp gene. A median of 0.6 cfu.g-1(ranging from <0.1 to 242.7 cfu.g-1) of typical E. coli colonies was found in the carcasses. Shiga toxin-encoding genes (stx1 and stx2) were not detected, indicating that the chicken carcasses were negative for STEC. The intimin protein...

ABSTRACT The present study was carried out to investigate the influence of freezing-thawing cycles (0, 2, 4 and 6) on lipid oxidation and myowater contents and distribution. Nine replicates of chicken breast meat samples were used for each cycle. Lipid oxidation was determined by measuring peroxide value, and malondialdehyde (MDA) concentrations, which reflect thiobarbituric acid reactive substance (TBARS). Color was determined with a digital colorimeter. Muscle moisture contents were determined by drip loss and thawing loss, water holding capacity, and nuclear magnetic resonance (NMR). The results showed that, as the number of freeze-thaw cycles increased, meat redness decreased and MDA and peroxide values increased. Drip loss and thawing loss tended to...

This work evaluated the effect of gamma radiation on reducting the population of Staphylococcus aureus, Escherichia coli and Salmonella typhimurium in ground chicken breast stored under refrigeration. The experiment included a control and 4 doses of gamma radiation (2.0, 4.0, 6.0 and 8.0 kGy) along with 5 periods of storage under refrigeration (1, 7, 14, 21 and 28 days). Samples of ground chicken breast were inoculated with Staphylococcus aureus (ATCC 14458), Escherichia coli (ATCC 11105) and Salmonella typhimurium (ATCC 0626), irradiated at temperatures between 4 and 8°C and stored under refrigeration (5°C) for 28 days. The increased radiation dose and period of storage under refrigeration caused a reduction of Staphylococcus aureus, Escherichia coli and...
