How long doPretzelslast in the pantry once opened?

What opening the package actually costs

Opening the package is the decision that settles this page. Sealed, the item holds 9 months sealed in the pantry; once open it holds 3 weeks open in the pantry, the same food measured in weeks instead of months, a drop of 13 times.

Every storage figure the USDA publishes for this item

The USDA rates this item in the pantry and nowhere else, one of 84 foods of the 466 it files that way.

Turning the range into a date

Two clocks run on this item: one from the day it went into storage and one from the day the seal broke. Both are listed below, 2 rows in all.

• Once opened · in the pantryUse by3 weeks after the day you opened it

Is this window about safety or about taste?

The answer at the top of this page reads 3 weeks in the pantry once opened. The USDA rating this place at all is the USDA saying Pretzels keeps there, so the figure rates how good it will be. Past it, judge it by look and smell: this window rates how good the food will be, not the day it becomes a hazard.

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 Pretzels past its 3 weeks in the pantry once opened 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.

Is that a long time?

6 items in the Shelf Stable Foods list keep exactly as long as this item, 9 months, so they all share place 48 of 70 rather than being put in an order the data does not support. Among the 244 foods the USDA also gives a pantry figure, it keeps longer than 38% of them.

Items that behave the same way

All 3 of the 6 items nearest this item keep exactly as long as it does, 9 months, so the ranking around it is a tie rather than an order.

Products the USDA rates in the same places

This is a common shape of record: 30 of the 466 products are rated in the same places, pantry from the day of purchase and pantry after opening, and 7 of the nine slots are left blank on all of them. Sorted by how close their windows are to this one, the nearest are Gelatin, Tapiocas and Cereal, and the rest of that group is what the list below draws on. Of the 8 shown, 8 keep longer than this one. The longest-keeping of them is Lentils at 1 year.

The record this page is built from

This page is built from a single FoodKeeper row, record 394 — the source’s own number for it, not a position — one of the 661 rows in the snapshot. That row fills 2 of the nine storage slots with a time, and the binding figure on it is printed by the source in months, which is the unit this page keeps rather than converting it to days. Every figure here comes from one fixed snapshot, USDA FoodKeeper, retrieved 1 September 2026, and is not refreshed page by page.

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.
