How long can perishable food be left out at room temperature?

Perishable food should not be left out at room temperature for more than 2 hours as this time frame is critical for food safety. When food is in the temperature danger zone, which is between 41°F and 135°F (5°C and 57°C), bacteria can multiply rapidly. After 2 hours, the risk of foodborne illnesses increases significantly, as harmful bacteria can double in numbers within 20 minutes at room temperature.

This guideline helps to minimize the chances of food spoiling or becoming unsafe to eat. Temperatures beyond this time can lead to food becoming unsafe, even if it appears normal or smells fine. Therefore, understanding and adhering to the 2-hour rule is essential for anyone handling perishable foods to ensure the safety and quality of the food served.
