 Preliminary FoodNet Data on the Incidence of Foodborne Illnesses 
--- Selected Sites, United States, 2000

 
 


 


 Each year in the United States, an estimated 76 million persons contract 
foodborne illnesses ( 1 ). CDC's Emerging Infections Program Foodborne Diseases 
Active Surveillance Network (FoodNet) collects data about nine foodborne diseases in 
eight U.S. sites to quantify and monitor foodborne illnesses 
( 2 -- 5 ). This report describes preliminary surveillance data for 2000 and compares them with 1996--1999 data. 
The data indicate the relative frequency of diagnosed infections, demonstrate 
substantial regional variation, and suggest trends in incidence. FoodNet provides data 
for monitoring foodborne illnesses and interventions designed to reduce them.

 In 1996, active surveillance began for laboratory-confirmed cases 
of Campylobacter, Escherichia coli O157, 
 Listeria monocytogenes, Salmonella, Shigella, 
Vibrio, and Yersinia entercolitica infections in Minnesota, Oregon, and 
selected counties in California, Connecticut, and Georgia. In 1997, surveillance for 
laboratory-confirmed cases of 
 Cryptosporidium spp. and Cyclospora 
cayetanensis infections was added, and 12 Georgia counties and Fairfield County in Connecticut were added to 
the surveillance area. In 1998, the surveillance area for Connecticut became 
statewide and active surveillance began in selected counties in Maryland and New York. In 
1999, the remaining counties in Georgia and eight counties in the metropolitan Albany, 
New York, area were added. In 2000, 11 counties in Tennessee and Contra Costa County 
in California were added, bringing the FoodNet surveillance population to 29.5 
million persons (10.8% of the 1999 U.S. population) 
( 6 ). To identify cases, surveillance personnel contact each clinical laboratory in their surveillance area either weekly 
or monthly depending on the size of the clinical laboratory. Cases represent the 
first isolation of a pathogen from a person by a clinical laboratory; most specimens 
were obtained for diagnostic purposes from ill persons.

 Preliminary incidence figures for 2000 were calculated using the number of 
cases of diagnosed infections that FoodNet had identified at clinical laboratories as 
the numer
