About Foodborne Illness

The Centers for Disease Control and Prevention (CDC) estimates that 76 million foodborne illness cases occur in the United States every year.  This amounts to one in four Americans becoming ill after eating foods contaminated with such pathogens as E. coli O157:H7, Salmonella, Hepatitis A, Campylobacter, Shigella, Norovirus, and Listeria.

On an annual basis, approximately 325,000 people are hospitalized with a diagnosis of food poisoning, and 5,000 die.  The annual dollar costs of foodborne illnesses—in terms of medical expenses and lost wages and productivity—range from $6.5 to $34.9 billion (Buzby and Roberts, 1997; Mead, et al., 1999).

While most foodborne illness cases go unreported to health departments, nearly 13.8 million food poisoning cases are caused by known agents—30% by bacteria, 67% by viruses, and 3% by parasites (Mead, et al., 1999).

In 2005, the CDC, Food and Drug Administration (FDA), and United States Department of Agriculture (USDA) released a report that showed important declines in foodborne infections due to common bacterial pathogens in the previous year (MMWR, April 15, 2005).  The report’s authors found that from 1996-2004, the incidence of E. coli O157:H7 infections decreased 42 percent.  Reports of Campylobacteriosis decreased 31 percent, reports of Cryptosporidiosis dropped 40 percent, and reports of Yersiniosis decreased 45 percent.  The incidence of Salmonella infections dropped 8 percent, but illness attributed to only one of the five most common strains declined significantly. The incidence of Shigella did not change significantly from 1996 through 2004; Vibrio infections increased 47 percent.
