FoodNet is an active laboratory- and population-based surveillance system for to
monitor the incidence of foodborne diseases of local and national public health importance.
Objectives are to:
- Determine the burden of foodborne illness
- Monitor trends in the burden of specific foodborne illnesses over time
- Attribute the burden of foodborne illness to specific foods and settings
- Develop and assess interventions to reduce the burden of foodborne illness
For foodborne disease outbreak reporting and investigation go to foodborne outbreaks.

FoodNet Ongoing Surveillance Activities
Foodborne Diseases Active Surveillance Network
Surveillance is conducted for seven bacterial and two parasitic pathogens: Campylobacter, Cryptosporidium, Cyclospora, Listeria, Salmonella, Shiga toxin producing Escherichia coli (STEC) 0157 and non-0157, Shigella, Vibrio, and Yersinia.
- Active laboratory-based surveillance for foodborne pathogens
The core of FoodNet is population-based active surveillance of clinical laboratories in the participating sites. Clinical laboratories that test stool samples are contacted regularly to collect information on all of laboratory-confirmed cases of foodborne illness.
- Survey of the population
The population survey is conducted to precisely estimate the burden of acute diarrheal illness and to describe the frequency of important exposures.
- Survey of clinical laboratory practices
The periodic laboratory survey is conducted to determine which pathogens are included in routine bacterial stool cultures, which tests must be specifically requested by the physician, and which specific techniques are used to isolate the pathogens.
- Survey of physicians
The periodic survey is conducted to understand knowledge, attitudes and practices of physicians.
- Disease attribution.
FoodNet Special Studies
Oregon EIP Foodborne Diseases Active Surveillance Network Special Studies
Identifying human genomic factors associated with the development of hemolytic uremic syndrome (HUS) among persons infected with Shiga-toxin producing E. coli (STEC) and calculate the proportion of disease risk attributable to these genetic factors. Cases with STEC infections are asked for a saliva sample, which is then analyzed for genetic markers. Abstract
Non-O157 STEC Case-Control Study
Identifying behavioral, environmental, dietary, and medical risk factors for non-O157 Shiga toxin-producing E. coli infection and to describe clinical and microbiological features of illnesses caused by different types of non-O157 STEC. Abstract
To see all Oregon Emerging Infections Program special studies go to EIP special studies.
