“Best by” labels on canned foods such as corn, green beans, and tuna indicate when the product is expected to be at its highest quality. These labels do not represent expiration dates, and many canned items can remain usable beyond the printed date when stored correctly. Understanding how these labels work can help reduce unnecessary waste while still maintaining safety.
Canned vegetables like corn and green beans can typically remain in good condition for one to two years past the “best by” date when kept in a cool and dry place. While the flavor or texture may gradually change over time, the product can still be suitable for use if the container remains in proper condition. Canned tuna, known for its extended shelf life, can remain usable for three to five years past the labeled date with appropriate storage, though mild decreases in quality may occur over long periods.
To ensure safety, always check cans for any signs of damage. This includes issues such as bulging, rust, or leaks. If you notice an unusual smell or appearance after opening a can, it is best to discard it. These simple checks help ensure both safety and quality when using canned goods that have been stored for an extended time.
Proper storage plays an important role in maintaining the condition of canned foods. Store cans in a cool, dry, and dark environment, and keep them upright. Using a rotation system helps ensure older products are used first. After opening a can, transfer any unused portions into a sealed container and refrigerate. By following these guidelines, you can make the most of your canned items while maintaining safety and quality.
