Understanding “Best By” Labels on Canned Foods
Canned foods are convenient and have a long shelf life, but many people misunderstand the meaning of “best by” or “best before” dates. These dates indicate when the food is at its best quality, not its safety. With proper storage, canned foods can remain safe well beyond these dates.
The Significance of “Best By” Labels
The “best by” date marks the period for peak flavor, texture, and nutritional value. It does not mean the food is unsafe after this date. If stored properly and the can remains undamaged, canned foods can last longer than this date.
Quality vs. Safety
“Best by” dates are about quality, not safety. After the date, food may lose flavor, color, or texture, but it can still be safe to eat. For instance, canned corn or tuna can remain safe well past the “best by” date if the can is undamaged.
Shelf Life of Common Canned Foods
-
Canned Vegetables (Corn, Green Beans): Safe for 1-2 years past the “best by” date with proper storage.
-
Canned Tuna: Safe for 3-5 years due to preservation methods.
Inspecting Canned Foods
Always check for damage, such as bulging, rust, dents, or leaks. If you notice any of these issues, discard the can. Also, trust your nose—if the food smells off, throw it out.
Storing Canned Foods
-
Temperature: Store cans in a cool, dry place (50°F-70°F).
-
Humidity: Avoid moisture to prevent rust.
-
Light: Keep cans in dark areas to maintain quality.
Expert Recommendations
-
Use “Best By” Dates as Guidelines: These dates are about quality, not expiration.
-
Inspect Regularly: Check cans for damage and discard any compromised products.
-
Proper Storage: Store cans in cool, dry, and dark places. Rotate stock regularly.
