In the spring of 2003 Salmonella was detected in a fattening pig herd in south-central Sweden. Because of the identified serotype there was an early suspicion of feed contamination, although monitoring did not reveal any Salmonella-positive samples in the feed mill. The finding in the pig herd resulted in a very large and costly outbreak investigation that went on for several months. The case demonstrates aspects of the Swedish programme for Salmonella control in primary production.
