A proactive attempt to control an outbreak of foodborne disease in humans after detection of Salmonella during surveillance and control of pork in Denmark

Based on Kuhn et al. (2012), this chapter describes the course and investigation of a large Danish foodborne outbreak in 2010, caused by a rare Salmonella Typhimurium phage type with the majority of patients residing in the eastern and southern parts of Denmark. It describes the interview studies conducted and the changes in the Salmonella subtypes and human demography during the outbreak. It also suggests interpretations of these changes. Comprehensive Danish register data on herds, slaughterhouses and Salmonella surveillance were utilized for the tracing of products and herds and for assessing the risks of herds, slaughterhouses and meat production plants being the source of infection in the outbreak.
