Question: 1 / 400

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

4 hours

1 hour if above 90°F

2 hours

Food safety guidelines recommend that perishable food should not be left at room temperature for more than two hours. This is because, within this time frame, bacteria can grow to levels that may cause foodborne illness. The "two-hour rule" is particularly important in preventing the growth of harmful pathogens that thrive at temperatures between 40°F and 140°F, known as the temperature danger zone.

Leaving food out for longer than two hours increases the risk of bacterial growth, which can lead to foodborne diseases. If the temperature is above 90°F, the maximum time food should be left at room temperature is only one hour, as higher temperatures accelerate bacterial growth.

In summary, the guideline emphasizes that food should not be left unattended at room temperature for more than two hours to ensure it remains safe for consumption.
