Food-poisoning bacteria that produce toxin in the gastrointestinal tract following their ingestion include Bacillus cereus, Clostridium perfringens, enterotoxigenic E. coli, and V. cholerae. Bacillus cereus and C. perfringens are spore-forming bacteria that often survive cooking and grow to large numbers in improperly refrigerated foods. Following ingestion, their cells release enterotoxins in the intestinal tract. Enterotoxigenic E. coli is a leading cause of travelers' diarrhea.
Enterotoxin: n. A toxin produced by bacteria that is specific for intestinal cells and causes the vomiting and diarrhea associated with food poisoning.
