USDA analysis of Salmonella contamination frequency on chicken carcasses and parts

Data published by the USDA Food Safety and Inspection Service (FSIS) investigate the frequency of Salmonella-positive chicken carcasses affects the prevalence of Salmonella-positive chicken parts samples across slaughter establishments. The regression analysis performed suggested a slight negative relationship between the prevalence of Salmonella-positive chicken parts in slaughter establishment and the use of peracetic acid on carcasses. The analysis also suggested a large positive relationship between prevalence of Salmonella-positive chicken parts and carcasses. However, the regression model has very limited predictive value. After adjusting for errors in the observed results, the estimated correlation of the frequency of Salmonella-positive chicken carcass and parts is 0.54. According to the researchers, this implies a moderate degree of relatedness between contaminated carcasses and parts. Pathogen interventions should reduce the correlation of prevalence, they concluded. @ https://www.sciencedirect.com/science/article/pii/S0956713518306315?dgcid=rss_sd_all" rel="nofollow noopener noreferrer" target="_blank">https://www.sciencedirect.com/science/article/pii/S0956713518306315?dgcid=rss_sd_all
