Question: 1 / 400

How long can food sit out at room temperature before it becomes unsafe?

1 hour

2 hours

Food that has been left out at room temperature can become unsafe to eat due to the rapid growth of bacteria. The USDA (United States Department of Agriculture) guidelines indicate that food should not be left out for more than 2 hours in what is called the "danger zone," which is the temperature range between 41°F (5°C) and 135°F (57°C). After this time frame, the risk of harmful bacterial growth increases significantly, making the food unsafe for consumption.

Understanding this timeframe is crucial for maintaining food safety and protecting against foodborne illness. The 2-hour rule helps individuals manage the risks associated with serving and storing food, especially during gatherings or when food is left out for extended periods.
