“Best by” and “best before” dates on food products can often be misunderstood, leading many people to toss out perfectly good canned goods prematurely. Contrary to popular belief, these dates do not indicate the expiration of a product or suggest that it is no longer safe to consume. Instead, they reflect the manufacturer’s estimate of when the food will be at its peak quality in terms of flavor and texture. This article will explore the significance of “best by” dates on canned foods like corn, green beans, and tuna, and provide you with practical tips on how long you can safely use these products beyond their labeled dates.
Understanding ‘Best By’ Dates
“Best by” dates are often confused with expiration dates, but there’s an important distinction between the two. While an expiration date is meant to indicate the point after which a product may no longer be safe to consume, a “best by” date is simply a recommendation for when the product will be at its freshest and most flavorful. After this date, the quality of the food may gradually decline, but it does not necessarily mean the food is unsafe to eat. For canned goods, which are preserved through a vacuum-sealed process, the contents can remain safe for a considerable period beyond the labeled date—provided they are stored correctly.
How Long Can You Use Canned Foods Beyond the ‘Best By’ Date?
Canned Corn
Canned corn is a pantry staple that is often used in soups, salads, and casseroles. The good news is that canned corn can typically remain safe for consumption for up to 1-2 years past its “best by” date, as long as it’s been stored properly in a cool, dry place. However, keep in mind that while the corn may still be safe to eat, its quality, such as texture and flavor, may start to diminish over time.
Safety Tip: Before using canned corn, always inspect the can for any signs of damage, including bulging, rust, or leaks. A compromised can could indicate spoilage or contamination, and it’s best to discard it.
Canned Green Beans
Canned green beans, another household favorite, have a similar shelf life to canned corn. When stored under the right conditions, canned green beans can be used for up to 1-2 years past their “best by” date. Again, while the beans may be safe to eat, the texture might become softer, and the flavor less vibrant.
