A cook with an infected cut on his hand assembles sandwiches with bare hands; the food sits out and guests vomit within 1 to 6 hours. Which pathogen produces a heat-stable toxin responsible for this rapid illness?

Staphylococcus aureus is often carried in the nose and on skin or infected wounds; when transferred to food that is then time-abused, it produces a heat-stable toxin causing rapid vomiting within 1 to 6 hours. Because reheating will not destroy the toxin, prevention relies on hand hygiene, covering wounds, no bare-hand contact with ready-to-eat food, and temperature control. Salmonella and Hepatitis A have much longer onset times.
