Handling and freezing notes

“Store perishable fresh fruits and vegetables (like strawberries, lettuce, herbs, and mushrooms) in a clean refrigerator at a temperature of 40° F or below.” FDA
“Mushrooms can be steamed or heated in fat in a fry pan. Steamed mushrooms will keep longer than those heated in fat.” Extension
“Mushrooms to be steamed have better color if given anti-darkening treatment first.” Extension
“Choose mushrooms free from spots and decay. Sort according to size. Wash thoroughly in cold water. Trim off ends of stems.” Extension

What the sources say

FoodKeeper gives fresh mushrooms 3 to 7 days in the refrigerator from the date of purchase, and 10 to 12 months in the freezer.¹

It gives no pantry time for fresh mushrooms.¹

The FDA names mushrooms, along with strawberries, lettuce and herbs, as perishable produce to keep in a clean refrigerator at 40 °F or below.³

Dried mushrooms last much longer: FoodKeeper lists 1 to 2 years in the pantry from purchase, and 3 months in the pantry once the package is opened.²¹

For freezing, the National Center for Home Food Preservation describes two ways to prepare mushrooms first: steaming them, or heating them in fat in a fry pan.⁵

It notes that steamed mushrooms keep longer than mushrooms heated in fat, and that mushrooms meant for steaming have better color after an anti-darkening treatment.⁵

Its preparation steps start with mushrooms free from spots and decay, sorted by size, washed in cold water and trimmed at the stem ends.⁵

CDC mentions mushrooms in its Listeria advice: it is investigating outbreaks linked to enoki mushrooms, and tells people at increased risk for infection not to eat raw mushrooms.⁴
