Turning the range into a date

Cashews keep 6 months sealed in the fridge. Counting 6 months forward from a date is not arithmetic anyone does reliably in their head. Give the field the day it went into storage.

The freezer helps less here than you would expect

The freezer buys less here than its reputation suggests: 2 times what the sealed fridge gives, 6 months against 12 months, both still measured in months. For this item freezing is an extension rather than a different way of keeping it. On the same shelf it sits 56 of 70, between Fruits, dried, raisins, apricots, mangoes, cranberries, etc. at 6 months and Roasted red peppers, jar at 6 months.

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.

Can you freeze cashews?

Yes. The USDA gives cashews 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. Freeze it well wrapped while it is still well inside its fridge window: the freezer keeps quality, it does not restore it.

How to tell if cashews have gone bad

Go by the date first: cashews keep 6 months sealed in the fridge. A sour or off smell, mold, slime or an odd color mean it goes out. The bacteria that make people sick change none of these, so past its window it goes out even if it seems fine. Never taste to test.

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

The answer at the top of this page reads 6 months in the fridge. What decides that is the food and not the shelf the source files it on: Cashews, no shell is acid, dry, sweet, alcoholic or pure fat. 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 Cashews, no shell past its 6 months in the fridge window. Past that the calendar stops deciding and the food itself does. A rancid, paint-like smell in a nut, an oil or a seed, mold around the neck of a bottle, or a swollen can 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.

Two places, and one of them is the wrong one

The USDA rates two places for Cashews, no shell in one state and they disagree: 6 months in the fridge against 2 weeks to 4 weeks in the pantry. This page answers with the refrigerator, the longer of the two. Both figures are the USDA's own, so this is a choice of where to put the food rather than a disagreement about how long it keeps.

Items that behave the same way

All 5 of the 6 items nearest this item keep exactly as long as it does, 6 months, 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.
