How Long Do Canned Foods Last?
When stored properly—in a cool, dry place away from direct sunlight—most canned foods can last 1 to 5 years past the printed date.
- High-acid foods (like tomatoes, pineapple, or other fruits) have a shorter shelf life. Over time, the acid can gradually react with the can lining.
- Low-acid foods (such as beans, corn, or canned meats) can last much longer—sometimes well beyond a decade.
In fact, the U.S. Department of Agriculture notes that as long as the can remains intact and undamaged, the food inside may remain safe indefinitely. While taste and texture can change, the food doesn’t automatically become dangerous after the printed date.
How to Tell If a Can Is No Longer Safe
Most expired canned foods are still fine, but there are clear warning signs that a can should be discarded immediately:
- Bulging or swollen can – may indicate bacterial growth producing gas.
- Leaking or rusted can – any break in the seal compromises safety.
- Severe dents, especially at the seams – could damage the protective lining.
- Unusual odor, color, or liquid spurting upon opening – clear signs of spoilage.
If in doubt, don’t taste it. Trust your senses and throw it out.
