title: Foodborne enteric infections.
abstract: Foodborne infections are estimated to affect one in four Americans each year. Most these (67%) are caused by the Norwalk-like viruses, but Campylobacter and nontyphoidal Salmonellae together account for about one fourth of cases of illness in which a pathogen can be detected. Less common bacterial infections, such as with Listeria monocytogenes and the Shiga toxin-producing Escherichia coli, cause fewer infections but are important because of their severe complications or high mortality rate, or both. This review describes the recent development of a national surveillance system for foodborne illness, newer methods for molecular characterization of organisms for epidemiologic studies, and individual etiologic agents in the order of frequency of occurrence. Methods for decreasing the disease burden are discussed, including education of health care professionals and the public, modification of food-handling behaviors, the use of food irradiation, and the application of probiotics to foods.
