How Long Can Cheese Sit Out?
For soft, shredded, low-fat, cottage and cream cheeses, use the 2-hour limit—or 1 hour above 90°F. FoodSafety.gov treats hard and processed cheeses as less perishable, so match the exact cheese type.
Decision table
| Situation | Limit or action | What it means |
|---|---|---|
| Soft cheese | 2-hour rule | Brie, cottage, cream, ricotta, mozzarella and similar |
| Shredded or low-fat cheese | 2-hour rule | Discard after prolonged warm exposure |
| Hard cheese | More tolerant | Cheddar, Swiss, Parmesan, provolone and similar |
| Processed cheese | More tolerant | Follow package directions |
| Unknown cheese type | Use the conservative rule | Refrigerate within 2 hours |
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.
