Navigating food expiration labels can be confusing—especially when it comes to “Best By” dates on canned goods. Many people think these labels mean food must be thrown out after the printed date, but that’s not true. In reality, a “Best By” date is simply the manufacturer’s estimate of how long the product will maintain peak quality.
With proper storage, canned items like corn, green beans, and tuna can last safely well beyond their printed dates. Here’s what you need to know.
What “Best By” Really Means
A “Best By” date is not an expiration date. Instead, it’s a quality indicator, suggesting when the food will taste its freshest. Canned foods are preserved through sealing and sterilization, giving them a much longer shelf life than fresh products.
Shelf Life of Common Canned Foods
Canned Corn
-
Can last up to 2 years past the “Best By” date if stored in a cool, dry place.
-
Texture and flavor may change slightly over time, but it’s still safe if the can is intact.
Canned Green Beans
-
Similar to corn, they remain safe for up to 2 years beyond the date.
-
Expect minor differences in taste or color with age.
Canned Tuna
-
Among the longest-lasting canned items, tuna can be good for 3 to 5 years past the “Best By” date.
-
Quality may decrease gradually, but proper storage ensures safety.
