Public Health Surveillance for Foodborne Infections: Design of Epidemiological Studies and Applying Seroepidemiology to Validate the Surveillance Pyramid

Statens Serum Institut (SSI)
Start date
  • To establish antibody decay profiles of immunoglobulin (Ig) A, IgG and IgM for persons with a stool culture-confirmed infection with S. Enteritidis (SE) or S. Typhimurium (ST) using a mixed salmonella ELISA (decay profiles for antibodies against campylobacter (CA) have already been established)
  • To measure antibodies against SE/ST and CA in ~5000 population-representative serum samples from several European countries
  • To estimate the incidence of SE/ST and CA infections in the population by using a mathematical back-calculation model
  • To calculate "multipliers" (i.e. the ratio between the number of infections in the population divided by the number of notified cases), which allow to 'calibrate' the surveillance systems of different countries
  • To develop a standard protocol for the application of the method beyond the scope of WP32
  • To make recommendations for additional studies, eg. to explore the protective effect of antibodies to foodborne pathogens and what implications this has for case-control studies of risk factors for foodborne pathogens and to compare the incidence of exposures leading to an antibody response in humans with quantitative risk assessment approaches
