Foodborne Diseases Active Surveillance Network (FoodNet)

Purpose

THE FOODBORNE DISEASES ACTIVE SURVEILLANCE NETWORK (FOODNET) is the foodborne disease component of CDC's Emerging Infections Program (EIP). FoodNet is a collaborative project among CDC, the 10 EIP sites, the Food Safety and Inspection Service (FSIS) of the United States Department of Agriculture (USDA) and the Food and Drug Administration (FDA). FoodNet consists of active surveillance for foodborne diseases and related epidemiologic studies designed to help public health officials better understand the epidemiology of infections commonly transmitted through food in the United States . FoodNet provides a network for responding to new and emerging foodborne diseases of national importance, monitoring the burden of foodborne diseases, and identifying the sources of specific foodborne diseases.  

Goals & Objectives

  • Determine the burden of foodborne illness in the United States
  • Monitor trends in the burden of specific foodborne illness over time
  • Attribute the burden of foodborne illness to specific foods and settings
  • Disseminate information that can lead to improvements in public health practice and the development of interventions to reduce the burden of foodborne illness.

Activities

  • In Connecticut, FoodNet conducts statewide, active laboratory-based surveillance for bacterial and parasitic foodborne pathogens on every laboratory-diagnosed case of bacterial pathogens including Salmonella , Shigella , Campylobacter , Escherichia coli O157 and other non-O157 Shiga toxin-producing E. coli (STEC), Listeria monocytogenes , Yersinia enterocolitica , Vibrio, and the parasitic organism causing Cyclospora infection. This information is transmitted electronically to CDC. In addition to collecting laboratory-diagnosed cases of foodborne pathogens, investigators at FoodNet sites conduct active surveillance for hemolytic uremic syndrome (HUS) (a serious complication of STEC infection). The result is a comprehensive and timely database of foodborne illness in a well-defined population.
  • Physician, Laboratory and Population Surveys
  • Case-control studies to identify risk factors for specific foodborne pathogens.
