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

Perishable food can safely be left out at room temperature for no longer than 2 hours. This guideline is based on the temperature danger zone, which is between 4°C (40°F) and 60°C (140°F), where bacteria can multiply rapidly. After 2 hours, the risk of foodborne illness increases significantly due to the growth of harmful bacteria.

It's essential for anyone handling food to understand this time limit to ensure food safety and prevent illness in themselves and others. For example, during events or gatherings where food may be left out on tables for extended periods, it's critical to monitor the time and take appropriate precautions, such as keeping food properly heated or chilled, to minimize health risks.
