How many hours cooked food can stay out at room temperature
Answer
Cooked food sitting at room temperature is in what the USDA calls the "Danger Zone," which is between 40°F and 140°F. In this range of temperatures, bacteria grows rapidly and the food can become unsafe to eat, so it should only be left out no more than two hours.
Don't leave cooked food at room temperature for more than 2 hours
