Unlike fresh potatoes, which only last about two months in the pantry, canned potatoes have the potential to last for two or three years at the very least.

Regarding concerns about expiration or “best by” dates, it’s important to understand that canned potatoes are likely to still be edible even if consumed after the indicated date.

Alongside shelf-stable ingredients, mayo contains eggs that can go bad even in a sealed jar. Avoid keeping more mayo than you can eat within a reasonable period.

Once you open a jar of mayo, store it in the fridge for no more than two weeks, and if you accidentally leave an open jar of mayo out overnight, toss it to avoid food poisoning.

Canned meats, like tuna, can stay in your pantry for a remarkably long time. An unopened and undamaged can of tuna can typically last between two to five years.

In the case of an emergency, it’s recommended that you have 5½ ounces of canned meat or plant protein available per day. Hence, canned meats are a must-have pantry staple.

While you can keep canned tomatoes in the pantry, don’t keep them for more than a year because they will erode as the acid starts to eat through the can.

If you have cans that start to smell bad, have sprung a leak, or generally give you the impression that what’s inside isn’t any good anymore, discard them immediately.

Of all the canned vegetables, corn has mostly the same taste and texture as fresh or frozen, making it a pantry win. Moreover, it’s a long-lasting canned food.

If you store canned corn at 40 F, expect it to retain its taste and quality for five or six years, and since your average can of corn is already cooked, you only need to heat it.
