Almost every pantry has one—a dusty can of beans, soup, or vegetables hiding in the back with a long-passed date stamped on the lid. When most people see that date, their first instinct is to toss it in the trash. But here’s the truth: expired canned food isn’t always unsafe.
In fact, according to food safety experts, most dates printed on canned goods are about quality, not safety.
Understanding Expiration Dates
Labels like “Best By,” “Best Before,” or “Use By” don’t necessarily mean the food becomes dangerous afterward. These dates mainly tell you when the product will taste its best—flavor, color, and texture may slowly decline after that time.
“Use By” dates are typically found on perishable foods like dairy and meat. For canned goods, the USDA notes that proper storage makes a big difference. Cans kept in a cool, dry place away from direct sunlight can stay safe well beyond their printed dates.
How Long Do Different Canned Foods Last?
The shelf life depends on what’s inside the can.
- High-acid foods (like tomatoes, fruits, or citrus): best within 12–18 months.
- Low-acid foods (like beans, corn, peas, or canned meats): can last 3–5 years—sometimes even longer.
According to the USDA, if a can is intact, rust-free, and undamaged, it may remain safe indefinitely. Over time, flavor and texture may fade, but the contents are generally still edible.
When to Throw It Out
Not all cans are created equal. If you notice any of these warning signs, it’s best to discard the product immediately:
- Bulging lids or sides
- Leaks or rust
- Deep dents (especially near the seams)
- Foul odor, discoloration, or spurting liquid upon opening
These are clear signs of spoilage or bacterial contamination, such as botulism—which can be deadly.
Smart Storage, Less Waste
By understanding how canned food works, you can save money and reduce food waste. Before tossing an old can, inspect it carefully. If it looks normal, smells fine, and the can is intact, it’s likely still safe to eat.
Being smart about food storage not only protects your health but also helps the environment by cutting down on unnecessary waste. So next time you clean out your pantry, remember—the date isn’t the whole story.
