How long doRetort pouches or boxeslast in the fridge once opened?

A short window, and what shortens it further

This item is one of the short-lived entries in the data: 4 days outside the freezer, position 10 of 17 in the Meat list. At that scale a day of delay is a large share of the whole window, which is why the figure is printed as a range rather than an average.

Every storage figure the USDA publishes for this item

The refrigerator is the only place the USDA gives this item a storage time, as it does for 64 of the 466 foods the USDA lists. Within Meat it is filed under Shelf Stable Foods.

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, 1 row in all.

Is this window about safety or about taste?

The answer at the top of this page reads 3 days to 4 days in the fridge once opened. What decides that is the food: the source files Retort pouches or boxes under Meat, a heading it keeps for perishable food. Past it, throw it out rather than taste it: a perishable food can carry enough bacteria to make you ill while it still looks and smells fine.

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 Retort pouches or boxes past its 3 days to 4 days in the fridge once opened window, or the container sat out on the counter overnight. Throw the container out without tasting it, and count any hours it already spent out of the refrigerator as part of that window rather than on top of it.

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 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?

Among the 17 items the USDA files under Meat, this item ranks 10 by how long it keeps outside the freezer. Venison, round, rump, loin, or rib roast holds 5 days, Bratwurst holds 3 days. Among the 340 foods the USDA also gives a refrigerator figure, it keeps longer than 16% of them.

Products the USDA rates in the same places

This is a common shape of record: 16 of the 466 products are rated in the same places, refrigerator after opening, and 8 of the nine slots are left blank on all of them. Sorted by how close their windows are to this one, the nearest are Fruit, cut, Cream pies and Jars or pouches, and the rest of that group is what the list below draws on. Of the ones shown, none keeps longer than this one does. The longest-keeping of them is Fruit, cut at 4 days.

The rest of the Shelf Stable Foods shelf

Shelf Stable Foods is a short shelf: 2 products besides this one. They run from Meat products at 5 years down to Jerky at 12 months, and this product sits with 2 products above it. A shelf this small is worth reading whole, which is why every one of them is printed below rather than a sample. The order counts the longest window outside the freezer, so this item sits here at 4 days rather than at the 3 days in the fridge once opened its own answer prints.

• Meat products5 years3 days in the fridge once opened

If it has to keep longer than this

If it has to keep longer than 4 days, the Meat aisle gives 5 products that hold at least twice as long outside the freezer. The smallest step up is Hot dogs at 2 weeks against this one's 4 days; after it come Pastrami, Prosciutto and Jerky. They are printed below in the order the step gets bigger, not alphabetically. In the other direction, 6 entries in the category keep half as long or less, Variety meats and Sausage among them. The largest step the category offers is Meat products at 5 years.

The record this page is built from

This page is built from a single FoodKeeper row, record 112 — the source’s own number for it, not a position — one of the 661 rows in the snapshot. That row fills 1 of the nine storage slots with a time, and the source prints its binding figure in days, so the window at the top of this page is the source's own number untouched. It is filed under Shelf Stable Foods inside Meat, which is where every shelf comparison on this page comes from.

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.
