Salmonella Typhimurium outbreaks in the Netherlands in 2008.

A large, countrywide outbreak due to multi-resistant Salmonella Typhimurium phage type DT104 is ongoing in the Netherlands, with 152 cases as of 20 October. Pilot interviews did not suggest any specific source of infection but a hypothesis pointing to pork products has been formulated and a large case-control study is under way. Earlier this year two other oubtreaks due to S. Typhimurium were detected and investigated, the first (DT15A) linked to a particular brand of cream cheese, the other (Dutch phage type ft507) to a local butcher.
