The Can Itself Is the Most Important Clue
Before opening an older can, inspect it carefully.
Throw the can away if you notice:
- A bulging lid or can
- Leaking liquid
- Significant rust, especially around seams
- Deep dents affecting the seams or edges
- Unusual discoloration
- Liquid that spurts out when opened
- An unusual or unpleasant odor
These signs can indicate that the container’s seal has been compromised or that the food may no longer be safe.
Never taste questionable canned food to determine whether it is safe.
Storage Makes a Difference
Where you store canned food matters.
A cool, dry pantry away from direct sunlight is generally preferable. Avoid storing cans in places exposed to excessive heat or moisture, as poor storage conditions can affect both the container and the food inside.
It’s also a good idea to rotate your pantry regularly so older cans are used before newer ones.
Don’t Confuse Quality With Safety
An older can may still be safe while having a noticeable change in quality.
The flavor, color, texture, or nutritional quality can decline over time. That doesn’t necessarily mean the food has become dangerous, but it may no longer taste as good as it did when it was fresh.
