Food left out calculator
Short answer: Perishable food can sit out for 2 hours, or 1 hour above 90°F (32°C). Enter the time it came out and the calculator gives you the time it has to be back in the fridge.
The rule the calculator uses
| Temperature | Longest perishable food can sit out |
|---|---|
| Up to 90°F (32°C) | 2 hours |
| Above 90°F (32°C) | 1 hour |
The time adds up across the whole meal. Food on a buffet table for 90 minutes and then in a warm car for 40 minutes has been out for over 2 hours. Perishable food means meat, poultry, fish, eggs, dairy, cooked rice and pasta, cut fruit and cooked leftovers.

Common questions
How long can cooked food sit out?
2 hours at room temperature, or 1 hour if it's above 90°F (32°C). After that, throw it out.
Can I put food in the fridge after it's been out 3 hours?
No. Perishable food that's been out more than 2 hours should be thrown out. Refrigerating it doesn't kill the bacteria that grew.
Do I have to let food cool before putting it in the fridge?
No. Put it in the fridge within 2 hours. Divide large amounts into shallow containers so they cool faster.
