Reliable active population-based surveillance of enteric diseases
|
FoodNet publishes incidence data for the previous year every spring. Rich database has comprehensive epidemiology and laboratory information about sporadic infections
|
Regulatory agencies evaluate their prevention efforts and change policies as a result of FoodNet data. Industry food safety executives use FoodNet data to inform policies. FoodNet data has been used to describe the epidemiology of infections caused by pathogens transmitted commonly through food in 162 publications. (More information is available at http://www.cdc.gov/foodnet/publications/index.html.)

Epidemiologic studies that determine risk and protective factors for sporadic enteric infections
|
A case–control study of Listeria infections showed that infection was associated with eating melons. Case–control studies of Campylobacter and Salmonella infections showed higher risk for infection among infants that had ridden in a shopping cart next to meat or poultry.
|
Because of study results, cantaloupe was added to Listeria initiative questionnaire, and this addition helped to more quickly identify cantaloupes as the source in the 2011 outbreak.
As a result, some retail stores are now providing bags near the meat and poultry counters and are providing wipes for cleaning shopping carts.

Population and laboratory surveys that describe the features of gastrointestinal illnesses, medical care–seeking behavior, foods eaten, and laboratory practices
|
Estimates were made in 1999 and 2011 of the actual number of foodborne illnesses, including those not confirmed by a laboratory test.
|
The 2011 estimates were used to help determine the number of illnesses that could be attributed to each major food category. Regulatory agencies are using the latter estimates to guide prevention efforts.

| Surveillance and research platform that can be adapted to address emerging issues |
In 2008, as more clinical laboratories began adopting culture-independent diagnostic tests (CIDTs) for enteric pathogens, FoodNet responded by gathering data on enteric pathogens detected by these tests. |
FoodNet worked with the Council of State and Territorial Epidemiologists to write a proposal to make Campylobacter infection diagnosed by either culture or CIDT a reportable condition nationwide. The proposal was approved in 2014, and reporting began in January 2015. |
