Turning the range into a date

Tuna (canned) keeps 3 years in the pantry. Each kind gets its own dated rows here, 3 rows across the 2 the USDA lists under this name, because a date is only worth printing against the window it belongs to.

The USDA rates 2 kinds of this separately

Tuna, packet keeps 3 days, which is shorter than the window this page answers with. The USDA files 2 separate entries under this name — packet and canned — and they do not keep for the same time: Tuna, packet holds 18 months outside the freezer, Tuna, canned holds 3 years.

Built to sit on a shelf

Tuna, canned is built to sit. It keeps 3 years outside the freezer. Among the 244 foods the USDA also gives a pantry figure, it keeps longer than 87% of them. It is long enough that the date it went into storage matters more than anything you can judge by looking at it. On the same shelf it sits 8 of 70, between Coconut oil at 3 years and Corn syrup at 3 years.

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. The source also indexes it as packet, retort, retort packaging and canned.

Can you freeze tuna?

The USDA prints no freezer time for tuna. Frozen at 0 °F any food stays safe; whether it is still good after thawing is a matter of quality. Keep the fridge at 40 °F or below and the freezer at 0 °F.

How to tell if tuna has gone bad

Go by the date first: tuna keeps 3 years in the pantry. Insects, a musty or rancid smell, clumping from damp, or a swollen can mean it goes out. Any dish you cook with it follows the 2-hour rule, 1 hour above 90 °F.

Is it still safe to eat, or just past its best?

The answer at the top of this page reads 3 years in the pantry. The USDA rating this place at all is the USDA saying Tuna, canned keeps there, so the figure rates how good it will be. 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 Tuna, canned past its 3 years in the pantry 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.

Items that behave the same way

Every one of the 6 nearest items keeps the same or less, 2 years to 3 years against the 3 years of Tuna, canned, which makes it the durable end of the cluster.

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.

Comparisons and the place in the category are computed for Tuna, canned, 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.
