Risk Assessment Comparing Alternative Approaches to Regulating Salmonella in Poultry by Public Health Impact Factors

A 1-year and 3 month project funded by US poultry:

The hypotheses of this project are:

  • Most illnesses from Salmonella in poultry are due to consumption of products with relatively high levels of contamination, e.g., > 1 CFU/g, of high-risk serotypes, e.g., Typhimurium.
  • Interventions based on identifying and controlling higher levels of contamination and higher-risk serotypes will result in more targeted effects than prevalence-based interventions, creating
    • Greater protection of public health (fewer predicted illnesses)
    • Greater benefit-cost ratios (less product rework, fewer recalls)

The project will test these hypotheses with the following objectives:

  • Build a farm-to-fork quantitative microbial risk assessment of Salmonella subtypes in poultry products incorporating different production strategies which will allow for assessment of the public heath impact of different interventions, performance standards, and regulations
  • Use the risk assessment to assess the likely impact on foodborne disease of interventions, performance standards, and regulations targeting Salmonella levels and/or specific strains
