Shigella So Common It Makes Top Three Among Food-borne Illnesses

Shigella was the third most common food-borne illness in the United States during 2008, according to the Foodborne Diseases Active Surveillance Network (FoodNet) of CDC's Emerging Infections Program, which collects data from 10 U.S. states.

The number of infections and incidence per 100,000 population were reported as follows:

  • Salmonella (7,444; 16.20),
  • Campylobacter (5,825; 12.68),
  • Shigella (3,029; 6.59),
  • Cryptosporidium (1,036; 2.25),
  • STEC O157 (513; 1.12),
  • STEC non-O157 (205; 0.45),
  • Yersinia (164; 0.36),
  • Listeria (135; 0.29),
  • Vibrio (131; 0.29),
  • and Cyclospora (17; 0.04).

* Per 100,000 population.
† Data for 2008 are preliminary.
§ Current Healthy People 2010 objective 10-1 targets for incidence of Campylobacter, Salmonella, Shiga toxin-producing Escherichia coli O157, and Listeria infections, and HUS.
¶ No national health objective exists for these pathogens.
** Shiga toxin-producing Escherichia coli.
†† Incidence of postdiarrheal HUS in children aged <5 years; denominator is surveillance population aged <5 years in sites that conduct hospital discharge data review (New Mexico excluded).
