How to Properly Read “Best By” Dates on Canned Foods
When you see a “best by” or “best before” date on a can of food, it’s easy to assume that the food must be thrown out once that date has passed. This is a common misconception that leads many people to discard perfectly good food. Understanding what these dates actually mean can help you make better decisions about the food in your pantry, reduce waste, and save money.
The “best by” date is provided by the manufacturer as a guideline for when the product is expected to be at its peak quality—when it tastes the best and has the best texture. However, this date is not a safety warning. Unlike expiration dates, which indicate when a product is no longer safe to consume, “best by” dates simply tell you when the manufacturer believes the food will be at its freshest.
For canned foods, which are designed to have a long shelf life, this means that the food is often safe to eat long after the “best by” date has passed, provided it has been stored correctly. However, the quality of the food might start to decline over time, affecting its flavor and texture.
What Do “Best By” Dates Really Mean?
The “best by” date is a suggestion from the manufacturer about when the food will taste its best. It’s not a safety warning. Canned foods are often safe to eat long after this date, especially if they’ve been stored properly in a cool, dry place. However, the quality—such as taste and texture—might decrease over time.
Canned Corn: Still Good After the Date
Canned corn can usually be eaten safely for 1-2 years after the “best by” date, as long as the can is undamaged and has been stored correctly. Before using it, check the can for any signs of damage, like rust, bulging, or leaks. If everything looks good, the corn is likely safe to eat, though the flavor might not be as fresh.
Canned Green Beans: Safe Beyond the Date
Like canned corn, canned green beans can also be used 1-2 years past the “best by” date if stored properly. However, always inspect the can before use. If the can is dented or leaking, it’s safer to throw it away. The texture and taste may not be as good, but the beans should still be safe to eat.
Canned Tuna: A Long-Lasting Option
Canned tuna can stay safe for up to 3-5 years after the “best by” date if stored in a cool, dry place. However, its quality may decline over time. Before eating, check the can for damage and examine the tuna’s smell, texture, and appearance when opened. If anything seems off, it’s best to discard it.
