†The 31 known pathogens are astrovirus, Bacillus cereus, Brucella spp., Campylobacter spp., Clostridium botulinum, Clostridium perfringens, Cryptosporidium spp., Cyclospora cayetanensis, enterotoxigenic Escherichia coli (ETEC), Shiga toxin–producing E. coli (STEC) O157, STEC non-O157, diarrheagenic E. coli other than STEC and ETEC, Giardia intestinalis, hepatitis A virus, Listeria monocytogenes, Mycobacterium bovis, norovirus, rotavirus, sapovirus, nontyphoidal Salmonella spp., S. enterica serotype Typhi, Shigella spp., Staphylococcus aureus, Streptococcus spp. group A, Toxoplasma gondii, Trichinella spp., Vibrio cholerae, V. vulnificus, V. parahemolyticus, other Vibrio spp., and Yersinia spp (1).
‡Unspecified agents are defined as agents that cause acute gastroenteritis other than the 31 major known pathogens listed above. They include known agents with insufficient data to estimate agent-specific episodes of illness; known agents not yet recognized as causing foodborne illness; microbes, chemicals, and other substances known to be in food but whose pathogenicity is unproven; and agents not yet described.
