The only date that directly links to food safety is the “Use By” date, and even then, it uses more commonly to sensitive items like dairy or meat—not canned foods.
How Long Do Canned Foods Last?
Under proper storage conditions—cool, dry, and away from direct sunlight—most canned foods can last 1 to 5 years past the printed date. Some items, like tomatoes or fruits with high acidity, may have a shorter shelf life because the acid can slowly respond with the lining of the can. On the other hand, low-acid foods such as beans, corn, or canned meats can often last much longer.
In fact, the U.S. Department of Agriculture highlights that as long as cans remain intact and free from damage, the food inside can remain safe indefinitely. While the taste and texture may alter over time, the food won’t automatically become harmful just because a date has passed.
How to Tell If a Can Is No Longer Safe
Although most expired canned goods are still fine, there are situations where you should definitely throw them out. Be cautious if you spot any of the following:
Bulging or swollen can: This could be a sign of bacterial growth or gas production inside.
Leaking or rusted can: Any break in the seal can let bacteria in.
