The short answer
Mushrooms lasts as long as you store it correctly — which can mean anywhere from a few days on the counter to a year in the freezer. The numbers above represent best quality per USDA and FDA guidelines, not absolute safety limits.
Why these numbers vary
Edible fungi — button, cremini, etc. Storage life depends on temperature consistency, humidity, packaging, and how fresh it was when you got it. Refrigerators that swing between 38°F and 45°F shave days off these numbers; vacuum-sealing or freezing extends them.
How to tell if mushrooms is bad

- Sour smell
Storage tips
