How long do Peanuts last in the fridge?
Turning the range into a date
Peanuts (no shell) keep 12 months sealed in the fridge. Each kind gets its own dated rows here, 8 rows across the 3 the USDA lists under this name, because a date is only worth printing against the window it belongs to.

The USDA rates 3 kinds of this separately
Peanuts, boiled, shelled keeps 7 days, which is shorter than the window this page answers with. The USDA files 3 separate entries under this name — shell, no shell and boiled, shelled — and they do not keep for the same time: Peanuts, shell holds 12 months outside the freezer, Peanuts, boiled, shelled holds 3 years.
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, 12 months against 24 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 38 of 70, between Macadamias, no shell at 12 months and Pistachios, shell or no shell at 12 months. Peanut, shell and nut 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 shell, nut, no shell and boiled.

Where the USDA answers in words instead of days
1 of the nine slots the USDA keeps for this item holds an answer that is not a number, and an answer in words is still an answer: in the freezer it answers Indefinitely, so kept that way the food does not run out of time, though it can still lose quality.
Can you freeze peanuts?
Yes. The USDA gives peanuts (no shell) 24 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 peanuts have gone bad
Go by the date first: peanuts keep 12 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 12 months in the fridge. What decides that is the food and not the shelf the source files it on: Peanuts, 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.
The figure in the fridge once opened here is a safety limit. The same page carries windows of more than one kind, so which sentence applies depends on which row you are reading, not on the food.
It is past the date. Now what?
Say the calculator above puts Peanuts, no shell past its 12 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 USDA's limit for perishable food standing at room temperature is 2 hours, or 1 hour when the kitchen is above 90 °F, and that clock runs whatever the storage figure 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 Peanuts, shell in one state and they disagree: 12 months in the fridge against 4 months in the pantry. Of the two, the refrigerator is the longer. 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 Peanuts, no shell keep exactly as long as it does, 12 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.
