Staphylococcal enterocolitis results from ingestion of foods containing which toxin?

• A. Thermostable enterotoxin
• B. Endotoxin
• C. Neurotoxin
• D. Pyrogenic toxin

Answer: (A)

Staphylococcal food poisoning comes from preformed enterotoxins produced by Staphylococcus aureus in contaminated food. These toxins are thermostable, meaning they resist normal cooking temperatures and can remain active even after the bacteria are killed. When ingested, the enterotoxin acts in the gut to trigger vomiting and rapid gastroenteric symptoms, often within a few hours. Endotoxin would come from gram-negative bacteria and isn’t the toxin behind this illness. Neurotoxins would affect the nervous system rather than cause classic food-poisoning GI symptoms, and pyrogenic toxins are linked to fever and systemic effects rather than the immediate enteric illness seen here.
