How long doesSeafoodlast in the fridge once opened?
What opening the package actually costs
Opening the package is the decision that settles this page. Sealed, the item holds 1 year in the pantry; once open it holds 2 days open in the fridge, the same food measured in days instead of years, a drop of 182 times.
Every storage figure the USDA publishes for this item
The USDA gives this item a pantry and a refrigerator figure and no freezer figure at all, the pattern behind 79 of the 466 foods in the data.

- Once opened · in the fridge1 day to 2 days
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.

Is this window about safety or about taste?
The answer at the top of this page reads 1 day to 2 days in the fridge once opened. What decides that is the food and not the shelf the source files it on: Seafood, canned is an animal food, or made with one. 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.
The figure in the pantry here is a quality window. 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. 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 Seafood, canned past its 1 day to 2 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?
12 items in the Shelf Stable Foods list keep exactly as long as this item, 1 year, so they all share place 26 of 70 rather than being put in an order the data does not support. Nothing the USDA puts in the refrigerator keeps a shorter time, and 32 of those entries share this same figure.
Items that behave the same way
All 5 of the 6 items nearest this item keep exactly as long as it does, 1 year, so the ranking around it is a tie rather than an order.

Products the USDA rates in the same places
Only 3 other products in the whole file carry the same set of rated places as this one, pantry and refrigerator after opening: Tomato sauce, White wine and Red wine. That is 3 products out of 466, which makes this a rare shape of record rather than a common one, and it is worth knowing that the comparison below is drawn from a very small group. Of the 3 shown, 2 keep longer than this one. The longest-keeping of them is Red wine at 5 years.

Closest by shape, but not an exact match — they share most of these places, not all of them.

The rest of the Shelf Stable Foods shelf
The USDA puts this product on the Shelf Stable Foods shelf together with 69 others, and 25 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 Bacon bits, Marshmallows and Nuts, which is the order the list below is printed in. Across the whole of Shelf Stable Foods the same product ranks 26 of 70. The middle of the shelf is Sunflower oil, at 1 year. 5 products on this shelf publish no window outside the freezer and stay out of the order.

If it has to keep longer than this
If it has to keep longer than 1 year, the Shelf Stable Foods aisle gives 21 products that hold at least twice as long outside the freezer. The smallest step up is Chocolate syrup at 2 years against this one's 1 year; after it come Molasses, Popcorn and Black pepper. They are printed below in the order the step gets bigger, not alphabetically. In the other direction, 15 entries in the category keep half as long or less, Fruits, dried and Cashews among them. The largest step the category offers is Sesame seeds at 5 years.

The record this page is built from
This page is built from a single FoodKeeper row, record 619 — 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 years, 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.
