Most kitchens have a forgotten can of beans, soup, or vegetables tucked away in the pantry. When the expiration date passes, many people assume it’s unsafe and throw it out right away. But in many cases, that isn’t necessary. The truth is that most dates on canned foods indicate quality, not safety.
“Best By” or “Best Before” dates are meant to show when the product will taste its best, not when it suddenly becomes unsafe. “Use By” dates are more common on perishable items like dairy or meat and are also about quality rather than strict safety. If canned food has been stored properly in a cool, dry place away from sunlight, it often remains safe long after the printed date.
Generally, high-acid foods like tomatoes or citrus are best eaten within 12–18 months for optimal flavor. Low-acid foods like beans, corn, and canned meats can last three to five years or more. According to the USDA, if a can is intact and undamaged, it can remain safe for an extended time, though the taste and texture may slowly decline.
Before discarding any canned food, inspect it carefully. Watch for warning signs such as bulging lids, leaks, rust, deep dents, unusual smells, or discoloration. If any of these are present, it’s best to throw it away. Otherwise, the food may still be perfectly usable. By understanding this, you can reduce waste, save money, and make smarter decisions about your pantry items.
