Turning the range into a date

Mushrooms keep 3–7 days in the fridge from purchase. Each kind gets its own dated rows here, 4 rows across the 2 the USDA lists under this name, because a date is only worth printing against the window it belongs to.

The USDA rates 2 kinds of this separately

The USDA files 2 separate entries under this name — USDA record 292 and dried — and they do not keep for the same time: Mushrooms holds 3 days to 7 days outside the freezer, Mushrooms, dried holds 1 year to 2 years.

Freezing changes the unit, not just the number

Here the freezer does not so much extend the answer as replace it. 7 days in the refrigerator becomes 12 months in the freezer: 51 times longer, and days turning into months. On the same shelf it sits 49 of 89, between Eggplant at 7 days and Rhubarb at 7 days. Mushroom and dried are the same food in the source list.

Every storage figure the USDA publishes for this item

All three places the USDA recognizes are rated here — pantry, refrigerator and freezer — which only 65 of the 466 foods in the data manage. The source also indexes it as dried.

Can you freeze mushrooms?

Yes. The USDA gives mushrooms 10–12 months in the freezer from the day you buy them, and held at 0 °F food stays safe beyond that: the figure is about quality. Most produce goes soft when thawed, so frozen it suits cooking, smoothies and sauces rather than eating raw.

How to tell if mushrooms have gone bad

Go by the date first: mushrooms keep 3–7 days in the fridge. Mold, slime, a sour smell or soft dark spots mean it goes out; firm produce can be saved by cutting 1 inch around a small moldy spot, soft produce cannot. Refrigerate cut or peeled produce within 2 hours.

Is it still safe to eat, or just past its best?

The answer at the top of this page reads 3 days to 7 days in the fridge. What decides that is the food and not the shelf the source files it on: Mushrooms is raw and whole. Past it, whether it has gone bad is yours to judge by look and smell: this window rates quality, not the day it turns hazardous.

It is past the date. Now what?

Say the calculator above puts Mushrooms past its 3 days to 7 days in the fridge window. Past that the calendar stops deciding and the food itself does. Mold, a slimy or sticky surface, soft or darkened spots, or a sour smell mean it goes out whatever the date says.

The whole rule, including the cases the source does not cover, is set out under what to do when the date has passed.

Items that behave the same way

All 6 of the 6 items nearest Mushrooms keep exactly as long as it does, 7 days, so the ranking around it is a tie rather than an order.

Where these numbers come from

Every storage time on this page is the USDA’s own published figure from the FoodKeeper data, one of the 9 it keeps per food, reproduced unchanged and never an estimate of ours. Where the USDA lists several kinds under one name, each kind keeps its own windows, and the page names the kind its answer is for. The dates and multipliers are ours, computed from those ranges.

Comparisons and the place in the category are computed for Mushrooms, which is the kind the plain name means here, chosen kind by kind rather than by the order the source happens to list them in.
