Swine specific strain of methicillin resistant Staphylococcus aureus (MRSA) has been identified from pigs in
various parts of the world. Data on the occurrence and magnitude of MRSA in swine herds reared in various
production systems in the United States and its potential transmission and possible implications for public
health via occupational and/or food safety means is limited. This serial cross-sectional study targets a set
of randomly identified conventional swine farms to determine MRSA in pigs. We also assessed the
likelihood of carriage or cross-contamination at slaughter and retail level and determine the potential food
- Determine the occurrence and prevalence of MRSA among swine herds on-farm, at lairage and carcass swabs and retail pork.
- Compare phenotypic and genotypic relatedness of MRSA isolated on-farm, at slaughter and from retail pork.
- Determine genotypic relatedness of MRSA isolated from pigs and pork with that of previously reported in humans and swine.
