What Happens When You Eat Expired Cans

Many kitchens have forgotten cans of beans, soup, or vegetables tucked away in the pantry. When people notice the expiration date, their first instinct is often to throw the food out. But in most cases, that may not be necessary.

Dates on canned foods usually indicate quality rather than safety. Labels like “Best By” or “Best Before” refer to peak flavor and texture, while “Use By” is typically found on perishable items such as dairy or meat. Slightly past-date canned goods may still be safe to consume.

Proper storage is key. Cans kept in a cool, dry place away from sunlight can often last far beyond the printed date without compromising safety.

High-acid foods, like tomatoes or citrus, maintain quality best within 12–18 months, whereas low-acid foods such as beans, corn, and meats can remain good for three to five years or more. The USDA notes that intact, undamaged cans may even remain safe indefinitely, though taste and texture can decline over time.

It’s important to watch for signs of spoilage. Bulging lids, leaks, rust, deep dents, unusual smells, discoloration, or spurting liquid when opened all indicate that a can should be discarded immediately.

Understanding these guidelines can help reduce unnecessary food waste, save money, and make food storage more efficient.

Before throwing out a can, inspect it carefully. If it looks and smells normal, it’s likely still safe and can provide a convenient, cost-effective meal. Proper handling benefits both your pantry and the environment.
