Many people toss out canned foods once they notice the expiration date, but that’s not always necessary. Most dates like “Best By” or “Best Before” indicate quality, not safety, meaning the food may still be fine to eat.

“‘Use By’ dates are typically found on perishable items like dairy or meat,” marking when the product is at its best rather than when it becomes unsafe. A can slightly past its date can still be good if stored properly.

Keeping cans in a cool, dry, and dark place helps them last longer. High-acid foods like tomatoes or citrus are best used within 12–18 months, while low-acid foods such as beans, corn, or meats can last three to five years or even more.

According to the USDA, if a can is undamaged and intact, it “can be safe indefinitely.” While taste and texture might fade over time, the food remains safe as long as the seal is secure.

Watch out for clear signs of spoilage—bulging lids, leaks, rust, dents, bad smells, or discoloration. Understanding canned food dates helps reduce waste and save money. Before throwing it out, check carefully—if it looks and smells normal, it’s likely still safe to eat.
