Most kitchens have at least one can of soup, beans, or vegetables hiding in the back of the pantry. When the expiration date passes, the instinct is often to throw it away immediately. However, most dates on canned goods are about quality rather than safety. Labels such as “Best By” or “Best Before” simply indicate when the flavor and texture are expected to be at their peak.
“Use By” dates appear more often on items like dairy, meat, or other perishables, and even then, the date usually refers to best quality rather than an automatic safety cutoff. With proper storage—keeping cans in a cool, dry place away from heat and sunlight—many canned foods stay good well beyond the printed date. High-acid foods such as tomatoes or citrus-based products generally taste best within 12 to 18 months.
Low-acid canned foods like beans, corn, and canned meats tend to last much longer, often three to five years or more. According to food safety guidelines, if a can remains intact and undamaged, it may stay safe for an extended period, though the taste may not be as fresh. Signs that a can should be discarded include bulging or swollen lids, rust, major dents, leaking, unusual odors, discoloration, or liquid spurting out when opened.
