Technical Abstract: The Collaboration in Animal Health & Food Safety Epidemiology (CAHFSE), a partnership among APHIS, ARS, and FSIS of USDA was established to track food borne pathogens and monitor diseases from farm through plant. Sampling began in July, 2003. By December 31, 2004, 43 farms in 5 states were participating. In this period, 139 site visits were made. At each quarterly visit, a questionnaire regarding management practices was administered, blood samples were collected for Lawsonia and PRRS serology and 40 fecal samples were collected from pigs >22 wks old for culture of enteric bacteria. All 5,161 fecal samples were cultured for Salmonella and 2066 (40%) for Campylobacter, E. coli, and Enterococcus. Salmonella was cultured from 549 (9.7%) of the samples. Campylobacter, Enterococcus, and E. coli were cultured from 1465 (70.9%), 1407 (68.1%), and 1857 (89.9%) of 2,066 samples cultured, respectively. The predominant Salmonella serotypes recovered were: S. derby (45%), S. Typhimurium var. Copenhagen (17.7%), S. heidelberg (7.4%), S. Typhimurium (5.4%), and S. give (4.6%). Approximately 94% of these were resistant to one or more antimicrobials.
