What is FoodNet?

The Foodborne Diseases Active Surveillance Network (FoodNet) is a collaborative project between DPH, CDC, and the Yale University Emerging Infections Program (EIP). It is the foodborne disease component of CDC’s EIP. The objectives of FoodNet are to describe the epidemiology of emerging foodborne pathogens, estimate the frequency and severity of foodborne diseases that occur in the United States each year, and determine the proportion of specific foodborne diseases associated with certain foods.

Currently, FoodNet conducts active laboratory surveillance for eight foodborne/enteric pathogens: Campylobacter, Cyclospora, Listeria, Salmonella, Shiga toxin-producing Escherichia coli (STEC) O157 and STEC non-O157, Shigella, Vibrio, and Yersinia. Data collected through DPH FoodNet are electronically submitted to CDC and contribute to national efforts to implement new food safety programs and regulations. Each year, as part of multi-site foodborne disease research studies, FoodNet staff may interview cases of specific types of foodborne disease to determine risk factors for acquiring infection. DPH notifies directors of health of these activities each year to request continue collaboration on follow-up interviews of cases to minimize the potential for duplication of efforts.

What is FoodCORE?

In 2012, DPH was awarded federal funding through CDC to become one of ten centers to join the Foodborne Diseases Centers for Outbreak Response Enhancement (FoodCORE). FoodCORE focuses on developing new and better methods to detect, investigate, respond to, and control local and multi-state foodborne disease outbreaks. A primary focus of FoodCORE is on outbreaks caused by bacteria, including Salmonella, STEC, and Listeria. FoodCORE also helps strengthen the detection and investigation of viral and parasitic foodborne disease outbreaks.
