IFSAC Releases Annual Report for 2023 on Sources of Foodborne Illness

Constituent Update

March 27, 2026

The Interagency Food Safety Analytics Collaboration’s newest annual report, “IFSAC 2023 annual report: Foodborne illness source attribution estimates for Salmonella, Escherichia coli O157, and Listeria monocytogenes, United States, a weighted approach using 1998–2023 outbreak data” is now available.

The IFSAC is a collaboration between the Centers for Disease Control and Prevention, the Food and Drug Administration, and the U.S. Department of Agriculture’s Food Safety and Inspection Service. 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.

The 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 annual reports as part of ongoing efforts to understand sources of foodborne illness in the United States. The CDC estimates that, together, these three pathogens — Salmonella, Escherichia coli O157, and Listeria monocytogenes — plus Campylobacter cause more than three million cases of foodborne illnesses in the U.S. each year.

The updated estimates, combined with other data, can help shape agencies’ priorities and inform the creation of targeted interventions that may help reduce foodborne illnesses caused by these pathogens. These estimates also inform stakeholders and improve our ability to assess whether prevention measures are working. For more information, visit IFSAC projects or email IFSAC@fda.hhs.gov.
