If you’ve ever rummaged through your pantry and stumbled upon a forgotten can of beans or soup long past its printed date, you’ve probably wondered whether it’s still safe to eat. Many people assume that expiration dates automatically mean danger, but the reality is far more reassuring.

The dates printed on canned goods, such as “Best By” or “Best Before,” are not strict safety deadlines. Instead, they are guidelines for peak freshness, flavor, and texture. After these dates, the food may lose some of its original taste or color, but it is often still perfectly safe to consume. Only “Use By” dates, which are more common on perishable items like dairy or meat, are closely tied to safety concerns—not canned foods.

When stored properly in a cool, dry place away from sunlight, canned food can last well beyond its labeled date. Many products remain safe for one to five years after the date has passed. High-acid foods, such as tomatoes or certain fruits, may not hold up as long because the acid slowly interacts with the lining of the can. Meanwhile, low-acid foods like beans, corn, or canned meats can last much longer. The U.S. Department of Agriculture even notes that as long as a can is intact and undamaged, the food inside may remain safe indefinitely, though the taste or texture may gradually decline.

Of course, not all expired canned food is safe. Certain warning signs should never be ignored. If a can appears swollen, leaks, or shows signs of rust, it’s best to throw it away. Severe dents, particularly along the seams, can also compromise safety. And if you open a can and notice a foul odor, unusual color, or liquid spurting out, that’s a clear signal to avoid eating it.

Understanding how expiration dates work matters more than most people realize. Every year, millions of cans are discarded simply because the printed date has passed, even when the food inside is still safe and nutritious. This unnecessary waste costs households money, contributes to food insecurity, and places added strain on the environment. By learning to recognize what’s truly unsafe versus what is still good, families can save money, reduce waste, and make smarter food choices.

The next time you discover an expired can tucked away in your cupboard, don’t be too quick to toss it. A careful check of its condition will often show that it’s still safe to enjoy, helping you get the most out of your pantry and your budget.
