Room Temperature Safety

The 2-hour rule states that perishable foods, including cooked onions, should not be left at room temperature for more than 2 hours. If the temperature is above 90°F (32°C), the limit is 1 hour.

The 'Danger Zone' for food is between 40°F (4°C) and 140°F (60°C), where bacteria can multiply rapidly.

Always refrigerate cooked onions promptly. Discard any cooked onions left in the danger zone for longer than the recommended time limits.
