Methicillin resistant Staphylococcus aureus (MRSA) in pigs
There are several varieties of Methicillin resistant Staphylococcus aureus (MRSA) some of which are associated with animals (especially pigs), and are collectively referred to as LA-MRSA (Livestock Associated - MRSA).
Within a few years, LA-MRSAs have become widespread in swine populations around the world, thereby representing a risk for dissemination to the human population.
Methicillin resistant Staphylococcus aureus (MRSA) has been surveyed yearly in pigs in Norway since 2014. The objective of the surveillance is to identify LA-MRSA positive swine herds with the intention of contact tracing and eradication, with an overall goal of keeping the Norwegian pig population free of LA-MRSA.
2022
The surveillance programme in 2022 did not detect any pig herds with MRSA. In total, 591 herds were included in the survey, of which 82 were genetic nucleus or multiplier herds, 11 herds were central units of the sow pool herds, 16 were of the largest farrow to grower or farrow to finish herds, and the remaining 482 were herds with more than 10 sows.
