Most kitchens have a forgotten can of beans, soup, or vegetables tucked away in the pantry. When people notice the expiration date has passed, the instinct is often to throw it away — but that isn’t always necessary. In many cases, dates on canned foods are about quality, not safety. Labels such as “Best By” or “Best Before” are meant to indicate peak flavor and texture rather than a strict deadline for consumption.
“Use By” dates are usually found on perishable products like dairy or meat, and even then, the date often refers to the manufacturer’s recommendation for best quality, not guaranteed spoilage. Properly stored canned foods — kept in a cool, dry place away from sunlight — can remain safe far beyond their printed dates. High-acid foods such as tomatoes or citrus generally taste best within 12 to 18 months, while low-acid foods like beans, corn, or canned meats can last three to five years or more. According to the USDA, if a can is intact and undamaged, it may remain safe indefinitely, though taste or texture may diminish over time.
However, there are signs that a can should never be eaten. Bulging lids, leaks, deep dents, rust, foul odors, discoloration, or liquid that spurts upon opening are clear indicators of spoilage. Any can showing these warning signs should be discarded immediately to avoid potential illness. Visual and smell checks are essential whenever a can seems questionable.
Understanding how canned food storage works helps reduce waste and save money. Before throwing out an expired can, inspect it closely. If the can is in good condition and the contents appear normal, it may still be safe to use. Smart, informed handling of canned goods benefits your budget, your pantry, and the environment.
