Many of us have that one dusty can hidden in the back of the pantry — the type you find during a kitchen clean-up and quickly check the expiration date on. When the date is past, the instinct is to throw it away, thinking it’s unsafe. However, here’s the surprising fact: many dates on canned goods relate more to quality than safety. Labels like “Best By” or “Best Before” are merely the manufacturer’s guess of when the food tastes best, not a strict deadline for when it becomes unsafe.
“Use By” dates, often seen on dairy or fresh items, can create even more confusion. These dates usually indicate peak quality rather than an automatic safety cutoff. For canned goods, proper storage is more important than the printed date. When stored in a cool, dry area away from heat and sunlight, most canned foods remain safe long after the label date. High-acid foods like tomatoes, pineapple, and citrus products typically keep their best flavor for 12 to 18 months, but they don’t suddenly become unsafe the day after the date.
Low-acid canned foods — such as beans, vegetables, soups, and canned meats — usually have a much longer shelf life, often lasting three to five years or more. Food safety experts point out that as long as a can is intact, undamaged, and properly sealed, the contents can be safe even after the date has passed. The real warning signs are physical changes: bulging or swollen lids, deep dents, rust, leaks, unusual odors, discoloration, or liquid spraying out when opened. If you notice any of these, the can should be discarded immediately.
Knowing what expiration dates really mean can help you save money, cut down on waste, and shop with more confidence. Before throwing away a can just because it’s past the printed date, take a moment to assess its condition. If it appears normal and smells fresh when opened, it might still be perfectly fine to use. Good storage practices and a bit of knowledge can enhance your pantry.
