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

Prepared food can be safely left out at room temperature for no more than 2 hours. This is based on food safety guidelines designed to minimize the risk of foodborne illnesses. The two-hour rule is important because bacteria can multiply rapidly in the temperature range known as the "danger zone," which is between 40°F and 140°F (4°C and 60°C).

If food is left out longer than this recommended time, the likelihood of bacterial growth increases significantly, leading to a higher risk of foodborne illness when the food is consumed. The 2-hour limit is especially critical for prepared foods that are not being held at safe temperatures, whether they are hot or cold. If the room temperature is particularly warm, such as during hot weather, this time frame can be reduced, emphasizing the need for vigilance in keeping food safe.
