Foodborne Diseases Active Surveillance Network


The objectives of the Foodborne Diseases Active Surveillance Network (FoodNet) are to: determine the burden of foodborne illness in the U.S.; monitor trends in the burden of specific foodborne illness over time; attribute the burden of foodborne illness to specific foods and settings; and disseminate information that can lead to improvement in public health practice and the development of interventions to reduce the burden of foodborne illness. The project consists of active surveillance for foodborne diseases at 10 collaborative Emerging Infections Program (EIP) sites and related epidemiologic studies.

Data Years Available: 
Mode of Collection: 
Selected Content: 
Laboratory-confirmed cases of Campylobacter, Cryptosporidium, Cyclospora, Listeria, Salmonella, STEC 0157, STEC non-0157, Shigella, Vibrio, and Yersinia. Demographic and outcome data are also collected.
Population Covered: 
Populations in 10 EPI sites (states or substate areas).

FoodNet conducts active population-based surveillance in 10 U.S. states for all laboratory-confirmed infections with select enteric pathogens transmitted commonly through food. FoodNet personnel regularly contact clinical laboratories to ascertain laboratory-confirmed cases of infection occurring within the surveillance sites. Hospitalizations occurring within 7 days of specimen collection date are recorded, as is the patient's status at hospital discharge or 7 days after the specimen collection date if not hospitalized. Deaths and hospitalizations are attributed to the pathogen if they occur within 7 days of the specimen collection date regardless of actual cause.
