Government-backed sitout guidance
How Long Can Pizza Sit Out?
The short answer
Pizza should not sit out for more than 2 hours, or more than 1 hour above 90°F (32°C). Refrigerate it before the limit or discard it.
Decision table
| Situation | Limit or action | What it means |
|---|---|---|
| Room temperature | Up to 2 hours | Refrigerate |
| Above 90°F (32°C) | Up to 1 hour | Refrigerate |
| Past the limit | Discard | Applies to pizza with any topping |
| Refrigerated pizza | 3–4 days | FoodSafety.gov cold-storage chart |
How to apply the rule
The clock is cumulative while perishable food is between 40°F and 140°F. Putting food back in the refrigerator does not erase earlier warm exposure.
The package instructions control when they are stricter. If the time, temperature, or handling history is unknown, the page cannot prove the food is safe; choose the conservative action.
Practical steps
- Identify the exact food, package state, and whether it is raw or cooked.
- Record the thawing method, storage temperature, and elapsed time that actually apply.
- Use the strictest applicable row in the table.
- Do not taste food to determine safety after excessive warm exposure.
