Fridge storage
How long do mushrooms last in the fridge?
About 3 days for mushrooms. That’s what Well Stockd plans on; the table below has the sources’ own times.
Times are for a fridge at 40°F (4°C) or below. They’re a guide, not a safety guarantee.
How we checked this: the storage times here come from USDA FoodKeeper and USDA FSIS, plus any other source named on the page, and each one is checked against its source before the page goes live. Editorial policy

How long they keep
- Unopened
- 4 to 7 days refrigerated Source: USDA FoodKeeper: Mushrooms (opens in a new tab)
- Opened or cut
- FoodKeeper gives no separate time for sliced mushrooms. Virginia Cooperative Extension says produce that has been cut should be eaten within 2 to 4 days or discarded. Source: Virginia Cooperative Extension: safe handling and storing of raw fruits and vegetables (opens in a new tab)
- Freezer
- About 10 months (300 days) at best quality. Frozen food stays safe indefinitely at 0°F; the time is about texture and flavor. Source: USDA FoodKeeper: Mushrooms (opens in a new tab)Compare freezer times for other foods on the printable freezer storage chart.
- How to store them
- Paper bag in the fridge, never sealed plastic. Cook before freezing: raw mushrooms freeze badly.
How to tell if mushrooms have gone bad
Dates are estimates; these are the checks that actually decide it. Don’t taste food to check whether it has gone bad.
Throw them out at once if you see:
- Slimy or sticky caps
- Ammonia smell
Warning signs (throw them out if you notice more than one):
- Dark wet patches
- Wrinkled, dried caps
Sources and limits
Write the date it went in on the container, and use it within 3 days. Don't wait for a weekly check.
Well Stockd doesn’t know when this food was harvested, packed, bought, opened or cooked. Write down the date you opened, cooked or refrigerated it, follow the package directions, keep your fridge at 40°F or below, and check the official listing when food safety is in question.
The times in the table come from USDA FoodKeeper, USDA FSIS guidance on refrigerated storage, and any source named beside a row. The number at the top is Well Stockd’s own estimate. It’s a guide, not a safety guarantee: FoodKeeper says storage times are guidelines, and quality varies with how food is grown, handled, shipped and stored. This page was last updated .
