How to store mushrooms
The best way to store fresh mushrooms is in a clean refrigerator at 40°F (4°C) or below. The FDA lists mushrooms as perishable fresh produce, which is why the fridge is the right place for them. Dried mushrooms are different and keep in the pantry.
How to store mushrooms in the fridge
Put fresh mushrooms in the refrigerator and keep it at 40°F (4°C) or below. If you bought them packaged or pre-cut, refrigerate them too, because the FDA says to refrigerate all produce bought that way.
Don’t leave mushrooms out of the fridge for more than 2 hours, or for more than 1 hour above 90°F (32°C). Bacteria grow fastest between 40°F (4°C) and 140°F (60°C), doubling in number in as little as 20 minutes.
Wait to wash them until right before you prepare or eat them, as the FDA advises.
