Prevalence of and risk factors associated with MRSA-ST398 carriage in 1872 (response 70%) farmers and neighbouring residents in a pig- and poultry-dense area in Germany were investigated using a cross-sectional study and self-sampling nasal swabs. In the population, 1% without occupational livestock contact and 24% with occupational livestock contact tested positive for MRSA-ST398. The group without occupational livestock contact was 3·8 times [95% confidence interval (CI) 1·5–9·3] more likely to be colonized if a household member had livestock contact and 3·2 times (95% CI 1·4–7·4) more likely if they regularly made private farm visits (e.g. to buy eggs or milk). In the group with occupational livestock contact, pig contact had an odds ratio of 7·1 (95% CI 2·9–17·2) for MRSA-ST398 acquisition. This is the first study to associate private farm visits with acquisition of MRSA; more research to explore the exact transmission routes is necessary.
