Does Canned Food Last Forever?

Canned food has long been a staple in American households. It is convenient, shelf-stable, and relatively inexpensive. But does canned food last forever? The answer is not so simple.

Canned food can last for years if stored properly. The key is to keep it dry and away from extreme temperatures.

Heat or cold can cause the cans to rust or warp, which will make them difficult to open and can contaminate the food inside. It’s also important to keep canned goods away from moisture, as this can lead to bacterial growth and spoilage.

The Expiration Date: Most canned foods have an expiration date printed on the can or lid. This is the manufacturer’s best guess as to how long the food inside will remain safe to eat. Generally speaking, canned goods are good for up to two years after the expiration date if stored properly.

Inspecting Canned Foods: Even if a food has not exceeded its expiration date, it’s still important to inspect it before eating it. Look for signs of rust or dents on the cans and any bulging lids or leaking liquid on the outside of the cans. If you find any of these issues, throw out the contents immediately.

Can You Freeze Canned Food? While some people believe freezing canned food will extend its shelf-life, this is not recommended by most experts as freezing temperatures can cause cans to expand and warp which may cause them to leak and contaminate their contents.

In conclusion, while canned foods do not last forever, they can last for several years if stored properly in a cool, dry place away from extreme temperatures. However, it’s still important to check for signs of spoilage before consuming them and never freeze canned goods as this could compromise their safety.
