The “Best by” date on canned goods, such as corn, green beans, and tuna, reflects the peak quality of the product rather than its expiration. Properly stored in a cool, dry place, these items can remain safe to eat 1–2 years past the labeled date. However, over time, the flavor and texture may begin to change gradually.
For example, canned corn and green beans typically maintain their safety and nutritional value well beyond the “Best by” date, as long as the cans show no signs of damage, such as rust, bulging, or dents. Tuna and other canned proteins also last considerably longer than expected if stored correctly.
Always inspect the can and contents before consuming. A foul odor, discoloration, or unusual texture indicates the food should not be eaten. Understanding the difference between “Best by” and expiration dates can help reduce unnecessary waste.
