An unusually high number of cases of Salmonella Typhimurium was reported in France in June 2008. In the course of epidemiological investigations 112 cases were ascertained, of whom 75 were interviewed. Subtyping by PFGE and MLVA identified a strain named "majority profile". Subtyping results were available for 45 interviewed cases, 30 of whom (majority below 15 years of age) were found to be infected with the majority profile strain.

An outbreak of Salmonella Typhimurium phage type U292 has been ongoing in Denmark since 1 April, with 1,054 cases registered until 23 October 2008. Extensive investigations have not provided clear indications of a specific source of infection but the main hypothesis is that the vehicle of the outbreak are different pork products.

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.

Through engaging a diverse pool of experts, we developed a model conceptualising disease spread as the outcome of interactions among sources, pathways and drivers. The factors perceived most likely to contribute to infectious disease spread in 2015 and 2030 included geographic extension of existing pathogens (partially due to climate change), over-use of antibiotics/antivirals/pesticides leading to drug resistance, and zoonoses.
