Methicillin resistantS. au reus in market hogs, retail pork, and swine veterinarians in the USA

摘要

Cross-sectional studies were conducted to obtain preliminary data on the prevalence of MRSA in swine veterinarians and market hogs, and S. aureus in retail pork in the USA. Convenience sampling was employed, but samples were broadly sourced across the country. Nasal swabs were collected from 111 swine veterinarians at a national swine veterinary meeting, and from 539 market hogs slaughtered at large US packing plants. Fresh pork products (chops or ground pork) were obtained from retail stores in 15 states. Samples were cultured using double enrichment methods and selective plating.
