How long do mushrooms last?
Mushrooms keep for 3 to 7 days in the fridge, up to 10 to 12 months in the freezer. USDA lists 2 kinds of mushrooms; the first is shown here and all are in the table below.

No guideline: USDA gives no time for that place, usually because the food is not stored that way.
How to tell mushrooms have gone bad
General signs for produce: fresh vegetables, the group USDA lists mushrooms under.
- Slimy, wet leaves on greens that were crisp before
- Soft or mushy spots on vegetables that were firm
- Sprouting or wrinkled skin on potatoes and onions
- Mould, often white or fuzzy, near the stem or cut end
- Sour or off smell replacing a vegetable's usual earthy scent
More on produce: fresh vegetables. The times above are quality guidelines, not safety limits; food that shows these signs goes out regardless of the date.
Storage habits that make the difference
Store leafy greens loosely wrapped in the crisper drawer, ideally with a paper towel to absorb extra moisture. Keep potatoes, onions and garlic in a cool, dark, dry place outside the fridge, and store potatoes away from onions since they spoil each other faster. Trim and wash vegetables just before cooking.
