MRSA CC398 (st398) in Pig Farm Households: A Pilot Study


Nothing unexpected here. Keep the children away from pigs!

Sad, isn't it, especially when the presence of MRSA st398 in British pigs has been hidden up for a decade?

Nobody thought it their job to protect the kids.

“…By restricting access to the stables and exposure to pigs, MRSA acquisition by household members could be greatly reduced."

The aim of this study was to determine the long-term carriage rates and transmission dynamics of 
methicillin-resistant Staphylococcus aureus (MRSA) in pig farmers and their household members. During a 6-month period in 2009-2010, 4 pig farms in Denmark, Belgium, and the Netherlands, respectively, were studied for the presence of MRSA. The proportion of persistent carriers was significantly higher among farmers than among household members (87% vs. 11%) and significantly higher in household members from Belgium compared to those from Denmark and the Netherlands (29% vs. 0% vs. 6%). Determinant analysis of MRSA carriage revealed that pig contact was the most important determinant for MRSA carriage among household members and that the increased MRSA carriage rate observed among household members from Belgium is linked to country-specific differences in pig exposure. These findings demonstrated that even in pig farms with very high carriage rates of MRSA both in livestock and farmers, the risk for household members to acquire MRSA is limited and still depends strongly on pig exposure. By restricting access to the stables and exposure to pigs, MRSA acquisition by household members could be greatly reduced
