Giải thích
Staphylococcus aureus lives in the nose, mouth, skin, and infected cuts of many healthy people and is transferred to ready-to-eat food by bare-hand contact; the toxin it forms is heat-stable and not destroyed by cooking. Controls include handwashing, no bare-hand contact with ready-to-eat food, and keeping food out of the danger zone. Freezing, acidity, or undercooking vegetables are not the transfer routes.
