Final answer:
If S. aureus bacteria from your skin get into your food and it stays at room temperature overnight, it is not safe to eat the food.
Step-by-step explanation:
If some of the Staphylococcus aureus (S. aureus) bacteria from your skin get into your food and then the food stays overnight at room temperature, it is not safe to eat the food because S. aureus can produce toxins that cause food poisoning. Staphylococcal food poisoning can cause symptoms like nausea, diarrhea, cramping, and vomiting within a few hours of ingestion. To prevent foodborne illness, it is important to thoroughly wash hands before preparing food, keep food refrigerated, and properly reheat cooked food to kill any bacteria.
