Nationwide Microbiological Baseline Data Collected by Sponge Sampling during 1997 and 1998 for Cattle, Swine, Turkeys, and Geese
Abstract:During 1997 and 1998, the U.S. Food Safety and Inspection Service completed nationwide microbiological baseline studies on four separate categories of livestock and poultry. Data were collected by sponge-sampling techniques. These studies were designed to provide nationwide estimates of the prevalence of Salmonella and prevalence and concentrations of Escherichia coli in cattle (n = 1,881), swine (n = 2,127), turkeys (n = 1,396), and geese (n = 102) in establishments under federal inspection. Salmonella prevalence ranged from 1.2% in cattle to 6.9% in swine, 13.7% in geese, and 19.6% in turkeys. The prevalence of E. coli was 16.6% in cattle (geometric mean = 0.26 CFU/cm 2), 44.1% in swine (mean = 0.78 CFU/cm 2), 92.7% in turkey (mean = 2.46 CFU/cm 2), and 96.5% in geese (mean = 1.97 CFU/cm 2). These values are similar to or somewhat lower than previous baseline values obtained for steers and heifers, cows and bulls, market hogs, and young turkeys. This study is the first in which nationwide microbiological baseline data have been compiled for geese. These data will be useful to individuals working with hazard analysis critical control point plans and risk assessment and to the research and academic communities.
