Many kitchens have a forgotten can of beans, soup, or vegetables tucked away in the pantry. Often, when the expiration date passes, people assume it is unsafe and throw it out immediately.
The truth is that most dates on canned foods indicate quality, not safety. Understanding this can help you reduce waste and save money.
“Best By” or “Best Before” Dates
These dates are meant to show when the product will taste its best. They are not necessarily a strict indicator of safety.
“Use By” Dates
More commonly found on perishable items like dairy or meat, these dates also mostly indicate quality rather than an immediate health risk.
Proper storage is crucial. Canned food stored in a cool, dry place away from sunlight can remain safe long after the printed date.High-Acid vs Low-Acid Foods
High-acid foods, such as tomatoes and citrus, are best eaten within 12–18 months for optimal flavor. Low-acid foods, like beans, corn, and canned meats, can last three to five years or longer.The United States Department of Agriculture confirms that if a can is intact and undamaged, it can remain safe for extended periods. Taste and texture may decline over time, but safety is usually not compromised.Before using canned food, always check for warning signs.A bulging lid is a clear indicator of spoilage. If a can is swollen, it should be discarded immediately.Dents and Damage
Deep dents, especially along the seams, may allow bacteria to enter. Shallow dents are less concerning but still should be monitored.Unusual Smells
If a can smells off or unusual when opened, do not taste it. Trust your senses.Discoloration
Changes in color or texture of the food inside can also indicate spoilage.
Reducing Waste
Understanding canned food labels helps reduce unnecessary waste. Many people throw away food that is actually safe to eat.
Safe Consumption Tips
When in doubt, transfer canned food to a glass or ceramic container and refrigerate after opening. Consume within a few days for safety.
Emergency Preparedness
Expired canned food is often safe enough for emergency kits. Rotate stocks periodically but don’t discard unnecessarily.
