• A. True
• B. Sometimes
• C. False
• D. Not sure

Answer: (A)

In a food intoxication the illness comes from toxins produced by microbes in the food itself, not from the microbes invading the body. When a preformed toxin is ingested, it can cause symptoms like vomiting and diarrhea even if the bacteria that made the toxin are no longer present or never enter the GI tract. For example, Staphylococcus aureus can produce enterotoxins in improperly stored foods, and some Bacillus cereus toxins survive cooking; the toxin itself triggers illness without requiring live bacteria to colonize the gut. This is different from foodborne infections, where the live organisms must be ingested and then multiply in the intestines to cause disease.
