Five farms have been mysteriously affected by an outbreak of salmonella in Skåne, southern Sweden.

The Swedish Board of Agriculture has so far not discovered the outbreak's cause. Speaking to Dagens Nyheter newspaper, the Board of Agriculture's veterinary inspector Elöd Szántó described the outbreak as one of biggest salmonella outbreaks of the last decade.

The farms are now been sanitised and a total of 700 calves, lambs and bulls have had to be put down.

Szántó believes that the infection could come via wild birds or rodents and they are currently investigating that possibility. Salmonella bacteria are not airborne bacteria but are passed on orally or through faecal matter.
