Researchers have developed a new quantitative risk assessment model for foodborne illness outbreak investigations that takes into account epidemic curves, and demonstrated its efficacy with a case study on a 2019 Salmonella outbreak linked to precut melons. 

A recent case study from the Sapienza University of Rome examined the surveillance of foodborne pathogens through a One Health lens in Europe, with a specific focus on the One Health European Joint Program (OHEJP) MATRIX Project framework.

Researchers from the USDA’s Economic Research Service and CDC developed a model that can be used to assess the value of state and federal foodborne illness outbreak investigations and subsequent recalls. The researchers demonstrated the replicability of the model using a 2018 Salmonella outbreak as a case study.

After a foodborne outbreak is identified, specific food vehicles may become the focus of an investigation based on the pathogen implicated and past outbreaks linked to the pathogen.
