How long doPecanslast in the fridge?
The USDA rates 3 kinds of this separately
Pecans, shell keeps 2 weeks, which is shorter than the window this page answers with. The USDA files 3 separate entries under this name — shell, no shell and chopped — and they do not keep for the same time: Pecans, no shell holds 9 months outside the freezer, Pecans, chopped holds 12 months.
The freezer helps less here than you would expect
The freezer buys less here than its reputation suggests: 2.7 times what the sealed fridge gives, 9 months against 24 months, both still measured in months. For this item freezing is an extension rather than a different way of keeping it.
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, no shell and chopped.

Turning the range into a date
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.

Is this window about safety or about taste?
The answer at the top of this page reads 9 months in the fridge. What decides that is the food and not the shelf the source files it on: Pecans, no shell is acid, dry, sweet, alcoholic or pure fat. Past it, judge it by look and smell: this window rates how good the food will be, not the day it becomes a hazard.
Held at 0 °F food stays safe for as long as it stays frozen, which is why a freezer figure counts as quality on this site whatever the food is. Every figure assumes the food was sound when you stored it, that your refrigerator holds 40 °F or below and your freezer 0 °F or below, and that the package was handled normally.
It is past the date. Now what?
Say the calculator above puts Pecans, no shell past its 9 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 FoodKeeper entry this page is built from prints storage times and nothing else, so anything past them here is USDA and FSIS guidance rather than a figure from the source. 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 Pecans, shell in one state and they disagree: 12 months in the fridge against 2 weeks to 4 weeks 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.
Is that a long time?
6 items in the Shelf Stable Foods list keep exactly as long as Pecans, no shell, 9 months, so they all share place 48 of 70 rather than being put in an order the data does not support. Among the 340 foods the USDA also gives a refrigerator figure, it keeps longer than 92% of them.
Items that behave the same way
All 3 of the 6 items nearest Pecans, no shell keep exactly as long as it does, 9 months, so the ranking around it is a tie rather than an order.
- Graham cracker/animal crackerkeeps exactly as long
- Pretzelskeeps exactly as long
- Tapenadekeeps exactly as long
- Crackerskeeps 3 months in the fridge once openedup to 8 months sealed in the pantry
- Almondskeeps 8 months sealed in the fridgeno shell

Products the USDA rates in the same places
No other product in the file is rated in exactly this set of places: freezer, freezer from the day of purchase, pantry from the day of purchase, refrigerator and refrigerator from the day of purchase, and nothing else. That makes the shape of this record unique among the 466 products here, so the closest comparisons available are the entries that share most of it — Almonds, Cashews and Macadamias. Their windows are printed beside them below, and none of them is rated in quite the same way.
Nothing carries this exact set of places, so these share most of it.

The rest of the Shelf Stable Foods shelf
The USDA puts this product on the Shelf Stable Foods shelf together with 69 others, and 47 of them keep longer outside the freezer. The shelf runs from Coconut cream at 5 years down to Polenta at 7 days. Nearest this product by window are Graham cracker/animal cracker, Gummy and Pretzels, which is the order the list below is printed in. Across the whole of Shelf Stable Foods the same product ranks 48 of 70. The middle of the shelf is Sunflower oil, at 1 year.

If it has to keep longer than this
If it has to keep longer than 9 months, the Shelf Stable Foods aisle gives 25 products that hold at least twice as long outside the freezer. The smallest step up is Applesauce at 18 months against this one's 9 months; after it come Fruit cocktail, Chia seeds and Peanut butter. They are printed below in the order the step gets bigger, not alphabetically. In the other direction, 7 entries in the category keep half as long or less, Pork rinds and Cashew butter among them.

The record this page is built from
The USDA publishes 3 separate rows under this name — records 443, 444 and 655 — and this page carries all of them rather than picking one, because their windows differ. Between them they fill 5 of the nine storage slots with a time. Comparisons and the place in the category are computed for Pecans, no shell, 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. The same record answers to shell, no shell and chopped in the source's own index.
Where these numbers come from
Every range on this page is published by the USDA FoodKeeper and reproduced unchanged. The multipliers, the rankings, the percentages and the dates are ours, computed from those ranges. Where the source gives a span such as 3 to 5 weeks, comparisons use the upper figure, and the full span is always printed.
Rankings cover only the items the USDA gives a usable figure for, and identical ranges share a place rather than being ordered arbitrarily. Neighbors are chosen by nearest storage time within the same category, never alphabetically: two foods filed next to each other by name usually have nothing to do with each other. The freezer is excluded from ranking because it flattens almost everything.
Where the USDA lists several kinds under one name, they share one page here and every kind keeps its own windows: the source prints them as separate rows, and a page that merged them would be inventing a figure the source never published. Comparisons and the place in the category are computed for the kind the plain name means — the shell egg for eggs, the can for tuna — which is settled name by name rather than by the order the source lists its rows in, and the page names it. Where the plain name means no single kind, the page prints no single figure at all and lists the kinds instead.
