15 Canned Foods That Can Last for Years—Sometimes Decades
In a constantly changing world, one thing remains essential: access to reliable, long-lasting food. Canned foods have earned their place in kitchens and emergency pantries thanks to their affordability, convenience, and impressive shelf life. What many people don’t realize is that some canned foods can remain safe and edible for many years—and in some cases, decades—when stored properly.
This article explores 15 canned foods with exceptionally long shelf lives and explains why they last so long.
Understanding Expiration Dates on Canned Foods
Expiration or “best by” dates on canned goods usually indicate quality, not safety. These dates mark when flavor and texture are at their peak. In reality, many canned foods remain safe well beyond these dates if:
The can is undamaged
Storage conditions are appropriate
There are no signs of spoilage
Why Some Canned Foods Last So Long
Certain foods naturally resist spoilage due to:
Low moisture content
High salt or sugar levels
Minimal fat content
High acidity
Combined with airtight sealing and sterilization during canning, these factors significantly slow bacterial growth.
How to Store Canned Foods for Maximum Longevity
To extend shelf life:
Store cans in a cool, dry place
Avoid direct sunlight and temperature swings
Do not use cans that are bulging, leaking, rusted, or badly dented
Inspect your pantry periodically
Safety First: When to Throw Canned Food Away
Even long-lasting canned foods should be discarded if you notice:
A foul or unusual odor
Discoloration
Spurting liquid upon opening
A damaged or swollen can
When in doubt, throw it out.
