Technical Abstract: The emergence of antimicrobial resistant zoonotic bacteria continues to be a global concern. In response to growing surveillance needs, USDA-ARS, APHIS and FSIS collectively developed CAHFSE. CAHFSE will enhance our overall understanding of pathogens that pose a food-safety risk by tracking these organisms from farm to plant. The first commodity of CAHFSE is pork. Blood and fecal samples have been collected on farms in four states through four quarters. Herd health and management data are also being collected from these farms. To date, fecal samples from 100 site visits have been collected and cultured for Salmonella, Campylobacter and E. coli. In the fourth quarter, 24 sites were visited and Salmonella was recovered from 7.5% (63/223) of the submitted samples. Eight serotypes were identified, of which the top three serotypes accounted for 86% of the isolates and included S. Derby, S. Bovis-morbificans, and S. Give. Across all serotypes, resistance was most commonly observed for tetracycline (91.0%), sulfamethoxazole (41.8%) and streptomycin (32.8%). Additionally, E. coli , Campylobacter and Enterococcus were recovered from 89.6% (303/338), 77.8% (263/338) and 65.7% (222/338) of samples, respectively. Over time, the epidemiology, phenotypic and genotypic characterization, and determination of risk factors related to prevalence and antimicrobial resistance of these organisms will lead to practical methods of mitigating food borne illness.
