Most current research on Campylobacter has focused on preharvest or processing plant cross-contamination. Little is known about the effect of storage environment on the survival of Campylobacter on raw poultry. We evaluated the effects of modified storage atmosphere and freezing on the survival of naturally occurring Campylobacter on raw poultry.…

The objective of this research is to determine the thermal inactivation kinetics of Listeria monocytogenes in chicken breast meat using both isothermal and dynamic conditions. A four-strain cocktail of L. monocytogenes was inoculated to chicken breast meat. Isothermal studies were performed by submerging samples under hot water maintained at…

Effects of spray washing carcasses with Lauric Acid (LA)-Potassium Hydroxide (KOH) on bacteria recovered from Whole-Carcass Rinsates (WCR) were examined. Carcass skin was inoculated with antibiotic resistant strains of Escherichia coli, Salmonella Typhimirum and Campylobacter coli. The first trial examined effects of washing carcasses with water,…

A real-time multispectral imaging system has demonstrated a science-based tool for fecal and ingesta contaminant detection during poultry processing. In order to implement this imaging system in the commercial poultry processing industry, the false positives must be removed. To do this, we tested and implemented additional image processing…

A spectral line-scan imaging system was developed for automated online wholesomeness inspection of broilers and evaluated in a commercial chicken processing plant. Real-time online hyperspectral images acquired by the system on a 140 bird-per-minute processing line were analyzed to optimize Region of Interest (ROI) size and location and to…

Campylobacter spp. are nutritionally fastidious organisms that are sensitive to normal atmospheric oxygen levels and lack homologues of common cold shock genes. At first glance these bacteria seem ill equipped to persist within food processing and storage conditions; however, they survive in numbers sufficient to cause the largest number of…

We investigated the heat resistance of an eight strain cocktail of Salmonella spp. in chicken supplemented with cinnamaldehyde (0 – 1.0%, w/w) and carvacrol (0 – 1.0%, w/w). Inoculated meat was packaged in bags which were completely immersed in a circulating water bath and held at 55 to 71C for predetermined lengths of time. The recovery medium was…

Chilling is a critical step in poultry processing to attain high-quality meat and to meet the USDA-Food Safety and Inspection Service temperature standards. This study was conducted to determine the effects of commercially available chilling systems on quality and safety of broiler meat. A total of 300 carcasses in 2 replications were randomly…

The current study was undertaken to acquire data on contamination of chicken parts with Salmonella at retail and to acquire data on cross-contamination of cooked chicken with Salmonella from raw chicken during meal preparation. Whole raw chickens (n ~ 31) were obtained from local retail stores and cut into two wings, two breasts without skin or…

A cross-sectional study was performed to estimate the prevalence of Salmonella on retail market chicken carcasses in Colombia. A total of 1,003 broiler chicken carcasses from 23 departments (one city per department) were collected via a stratified sampling method. Carcass rinses were tested for the presence of Salmonella by conventional culture…

Low pathogenicity avian influenza virus (AIV) H7N2 has been isolated since 1994 from retail live-bird markets (LBMs) in the northeastern United States. This study examines the suppliers to the LBMs in New York and New Jersey. In 2001, 185 supplier premises in nine states were surveyed for the presence of AIV by virus isolation (VI) in embryonating…

Nationwide sampling in the U.S. of whole large eggs, to update values in the United States Department of Agriculture (USDA) National Nutrient Database for Standard Reference (SR) (http://www.ars.usda.gov/nutrientdata), was conducted in 2000–2001 and in 2010. Retail cartons of large eggs were obtained from 12 supermarket locations using statistical…

Price transmission is a critically important issue that affects market enlargement and the unification of Canadian-U.S. agriculture. This study adopts alternative frameworks to examine the nature of cross-border integration in selected meat and livestock markets. The aim is to determine the extent to which selected meat and livestock markets…

The purpose of this article is to evaluate the impact of mergers and acquisitions (M&As) on wages, employment, and plant closures in the meat packing, prepared meat products, and poultry slaughter and processing industries during two merger periods, 1977-1987 and 1982-1992. The analysis relies on two balanced panel datasets of all plants owned by…

The exercise of market power by broiler processing firms (integrators) is plausible because local markets for growers are concentrated and because growers face hold-up risks arising from substantial investments in specific assets set against limited integrator purchase commitments. This article explores the links between local integrator…

The United States is the world’s second largest broiler meat exporter (after Brazil), and exports have become a valuable source of income for the U.S. broiler industry. This study examines the growth in broiler meat exports focusing on several major markets.

Between 1960 and 1995, U.S. broiler production grew by 5.6 percent per year, but a lack of growth since 2008 has placed new financial pressures on contract growers. This report uses USDA survey data to delineate the key features of the industry’s organization and to analyze its recent financial and productive performance.
