| Abstract: | The ultimate goal of controlling foodborne hazards is to reduce the risk of disease to consumers, and the economic burden related to foodborne illness. A literature review identified four areas of insufficient data on the epidemiology of Salmonella. A cross-sectional study was used to estimate prevalence of enteric bacterial contamination of plant-based animal feed and milk replacer from Maryland and Northern Virginia. All samples were negative for Campylobacter; 0.6% were positive for Salmonella; 5.7 % for E.coli; and 50.6% for Enterococcus. Samples purchased in summer of 2002 were 38 times more likely to be contaminated with Enterococcus than samples purchased in winter of 2002 (p-value<0.001). Enterococcus positive samples were 8 times more likely to be E.coli positive than Enterococcus negative samples.
Another cross-sectional study was used to assess the association between the pattern of airflow and the distribution of fecal coliforms and Salmonella in commercial chicken litt... |
