The results were analysed separately for breeding holdings and production holdings, due to the expected differences in MRSA occurrence in those types of holdings. Twelve of the 24 Member States isolated MRSA in breeding holdings, which resulted in a European Union prevalence of breeding holdings positive for MRSA and for MRSA ST398 of 14.0% and 13.1%, respectively. Prevalence varied widely among the Member States, from 0% to 46.0%.
The most frequently isolated spa-types belonging to MRSA ST398 were t011, t108 and t034. In addition, spa-types belonging to MRSA non-ST398 were detected in production holdings and, to a lesser extent, in breeding holdings. In particular, spa-types belonging to lineages ST5, ST8, and ST132, which are spa-types known in human medicine, were each isolated in different production holdings. Colonisation of pigs with MRSA ST398 has been identified as an occupational health risk for farmers, veterinarians and their families.
