Walk into almost any kitchen and you’ll seek a forgotten can of beans, soup, or vegetables hiding in the back of the pantry. Often, when people spot the date on the label has passed, the quick reaction is to toss it in the trash. But are those cans really unsafe to consume once they’ve passed the “Best By” or “Best Before” date? The truth may amaze you.
What Do the Dates Really Mean?
First, it’s crucial to understand that the dates printed on canned goods are not usually about safety. Instead, they are indicators of quality. A “Best By” or “Best Before” date shows you when the manufacturer thinks the food will taste its freshest. After that date, the flavor, texture, or color may reduce slightly, but the food is often still safe to eat.
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:
