Methicillin-resistant Staphylococcus aureus (MRSA) nasal colonization has been documented in swine and swine workers. MRSA has also been found in the shower facilities of conventional swine farms. We previously conducted a review of the literature to identify measures used to reduce MRSA prevalence in athletic facilities. In this study, we evaluated those measures for adaptability to the pork production environment. A best practices protocol was developed to reduce MRSA levels in pork production shower facilities and implemented in two conventional swine production systems. PMID: 22458012

Pork producers selected from the National Pork Board`s producer database were surveyed. Five (3.7%) reported being diagnosed with a MRSA infection. Risk factors related to swine farm biosecurity were examined. None were statistically significant predictors of MRSA infection. Free full-text PDF

As methicillin-resistant Staphylococcus aureus (MRSA) has been found in pigs, we sought to determine if MRSA is present in pork production shower facilities. In two production systems tested, 3% and 26% of shower samples were positive for MRSA. spa types identified included t034, t189, t753, and t1746. PMID: 21097587

Researchers, veterinary and health care practitioners, and agricultural producers gathered in Johnston, Iowa, to attend the eighth annual Midwest Rural Agricultural Safety and Health Forum (MRASH), November 2009. Among several focus areas, four plenary talks were given on the current research being conducted examining methicillin-resistant Staphylococcus aureus (MRSA) on swine farms in the United States.
These focused on prevalence of MRSA on farms, both in swine and in human workers; the presence of MRSA in air samples and in swine barn shower facilities; and the presence of methicillin-resistant and methicillin-sensitive S. aureus in retail meats. These findings begin to elucidate the overall picture of livestock-associated MRSA in the Midwestern United States. PMID: 20407991 [PubMed - indexed for MEDLINE]
