The Truth About Expired Canned Food: How Long Is It Really Safe?

How to Tell If a Can Is No Longer Safe

Although most expired canned goods are still fine, there are situations where you should definitely throw them out. Be cautious if you spot any of the following:

• Bulging or swollen can: This could be a sign of bacterial growth or gas production inside.
• Leaking or rusted can: Any break in the seal can let bacteria in.
• Severe dents, especially on the seams: Dents can compromise the safety of the can’s lining.
• Strange odor or appearance upon opening: If the food smells off, looks unusual, or spurts liquid unexpectedly, do not taste it.

These are signs that the food may no longer be safe, regardless of the date.

Why This Matters

Every year, millions of tons of food are wasted simply because people don’t understand expiration dates. Perfectly good canned goods are often dumped when they could still offer safe, nutritious meals. Not only does this waste money, but it also contributes to larger problems of food insecurity and environmental impact.By learning how to properly interpret food labels, households can reduce unnecessary waste and develop their grocery budgets further.
