Compliance to good farming practice is a substantial issue to increase animal health and food quality in pork production. In this case-control study, as part of a general framework, farmers were asked six questions via a face-to-face questionaire, in order to determine their motivation for Salmonella control on their farms. The cases were in the so called Category III (n=104) of the German Salmonella monitoring system; the controls were in Category 1 (n=67).
