November 4, 2022

The Interagency Food Safety Analytics Collaboration’s (IFSAC) newest annual report , “Foodborne illness source attribution estimates for 2020 for *Salmonella*, *Escherichia coli*O157, and *Listeria monocytogenes* using multi-year outbreak surveillance data, United States,” is now available.

IFSAC analyzes foodborne illness outbreak data for priority pathogens and specific foods and food categories that are responsible for foodborne illnesses in the United States. The data are analyzed by calendar year and released in an annual report as part of ongoing efforts to understand sources of foodborne illness in the United States. The Centers for Disease Control and Prevention (CDC) estimates that, together, these priority pathogens — *Salmonella*, *Escherichia coli* O157, *Campylobacter*, and *Listeria monocytogenes* — cause nearly two million cases of foodborne illnesses in the U.S. each year.

Unlike prior IFSAC Annual Reports, attribution estimates for *Campylobacter* are not presented in this year’s report. Evidence suggests the sources of *Campylobacter* outbreaks likely differ considerably from the sources of non-outbreak-associated illnesses caused by this pathogen. IFSAC is exploring alternative approaches for estimating the sources of *Campylobacter* illnesses.

The updated estimates, combined with other data, can help shape the priorities of the U.S. Food and Drug Administration (FDA), and inform the creation of targeted interventions to reduce foodborne illnesses caused by these pathogens. These estimates also inform stakeholders and improve our ability to assess whether prevention measures are working.

IFSAC is a collaboration between the CDC, the FDA, and the U.S. Department of Agriculture’s Food Safety and Inspection Service (USDA-FSIS). The group was established in 2011 to improve coordination of federal food safety analytic efforts and address cross-cutting priorities for food safety data collection, analysis, and use. For more information, visit IFSAC projects or email IFSAC@fda.hhs.gov.
