What is the maximum time food can be left out at room temperature?

• A. 4 hours
• B. 2 hours or 1 hour if the temperature is over 90°F
• C. 3 hours
• D. 5 hours

Answer: (B)

The maximum time food can be left out at room temperature is two hours, or one hour if the temperature exceeds 90°F. This guideline is crucial for ensuring food safety and preventing foodborne illnesses. When food is left out at room temperature, it provides an ideal environment for bacteria to multiply rapidly. The two-hour limit is based on the understanding that food in the temperature danger zone, which is 41°F to 135°F, can become unsafe to eat after this period. If the temperature rises above 90°F, it also accelerates bacterial growth, reducing the safe duration to one hour. Adhering to this guideline helps protect consumers by minimizing the risk of food contamination and illness.
