We’ve all experienced it — cleaning the pantry and finding a forgotten can of soup or beans with an old date on the label. The instinct might be to toss it, but the truth is many canned foods remain safe long after their printed dates. Labels like “Best By” or “Best Before” refer to quality, not safety, meaning the food may lose some flavor over time but doesn’t automatically become unsafe. The only label that directly relates to food safety is “Use By,” and that’s usually found on perishable items such as dairy or meat, not canned goods.
How Long Canned Food Really Lasts
When stored correctly — in a cool, dry place away from heat and sunlight — most canned goods can last one to five years past the printed date. High-acid foods like tomatoes or fruit may lose quality sooner, while low-acid items such as beans, corn, or canned meat often last much longer. According to the U.S. Department of Agriculture, as long as the can remains sealed, rust-free, and undamaged, the contents are typically safe to eat even beyond the suggested date, though the taste or texture may change slightly.
When to Discard Canned Food
Some cans, however, should never be used. Always throw away any that are bulging, leaking, rusted, or deeply dented near the seams. If the food inside has an unusual odor, appearance, or color, it’s best to discard it. Avoid tasting anything that seems questionable — safety should always come first.
Reducing Waste and Staying Informed
Many people throw away perfectly good food because of confusion over expiration dates. By understanding the difference between freshness labels and actual safety indicators, you can save money and reduce unnecessary waste. Proper storage and inspection go a long way in keeping your pantry both safe and sustainable. With a little knowledge, you can enjoy nutritious meals while preventing good food from going to waste — one can at a time.
