How Long Cans Can Really Last
With proper storage—in a cool, dry place away from sunlight—most canned foods last 1 to 5 years beyond the date on the label.
- High-acid foods (like tomatoes, pineapple, citrus): They have a shorter shelf life. Expect about 12–18 months past the date for the best taste.
- Low-acid foods (like beans, corn, canned meats): These last much longer—sometimes years past the label date.
The USDA even confirms that as long as the can is intact and undamaged, the contents can remain safe indefinitely. The flavor and texture may fade, but the food doesn’t suddenly turn unsafe once the date passes.

Signs That a Can Is Unsafe
While most old cans are fine, some warning signs mean you should not eat them:
- Bulging lid or sides → May signal unwanted gas or bacterial activity.
- Leaks or heavy rust → The seal might be broken, letting in contamination.
- Severe dents along the seams → Can compromise the can’s structure.
- Strange odor, unusual color, or liquid spraying when opened → Clear signs of spoilage.
