May 2008 A 10-state report released by the CDC showed little change in the incidence of some foodborne infections after a period of decline. The findings are from 2007 data reported to the CDC as part of the agency’s Foodborne Diseases Active Surveillance Network, FoodNet. FoodNet monitors foodborne disease and conducts related epidemiologic studies to help health officials better understand the epidemiology of foodborne diseases in the United States. Although the FoodNet population is similar to the U.S. population, the findings are used to detect trends in foodborne illness and should not be generalized for the entire U.S. population. Campylobacter, Listeria, Salmonella, Shigella, Escherichia coli O157, Vibrio and Yersinia did not decline significantly, and the estimated incidence of Cryptosporidium increased when compared with the previous three years (2004 to 2006). The incidence of Salmonella infections in 2007 (14.92 cases per 100,000) was the furthest from the national target for 2010 (6.80 cases). Although there have been significant declines in the incidence of some foodborne infections since surveillance began in 1996, these declines all occurred before 2004. The full report was published in the Morbidity and Mortality Weekly Report (2008;57:366-370). |
