Here’s What You Need to Know About Food Expiration Dates
When you open your pantry and spot canned corn, green beans, or tuna that’s past its “Best By” date, you might wonder if it’s still safe to eat. Many people assume these labels are strict expiration dates, but that’s not entirely true. In fact, understanding what “Best By” really means can save you money, reduce food waste, and give you peace of mind about what you’re serving your family.
What Does “Best By” Really Mean?
A “Best By” date is not the same as an expiration date. Instead, it’s the manufacturer’s recommendation for how long the product will maintain its peak quality—best flavor, texture, and freshness. Properly stored canned foods can remain safe well beyond that printed date, though there may be small changes in taste or appearance over time.
Shelf Life of Common Canned Foods
- Canned Corn
This pantry favorite can remain safe to eat for up to two years past the “Best By” date, provided the can is undamaged and stored in a cool, dry space. The flavor may not be quite as vibrant, but it will still be edible. - Canned Green Beans
Much like corn, green beans in a can can last about two years beyond the label date. While you might notice a softer texture or slight flavor change, it’s still safe if the can shows no signs of damage. - Canned Tuna
Tuna has one of the longest shelf lives of any canned food. Properly stored, it can last three to five years past the “Best By” date. Just keep in mind that quality may decrease with time, even though it remains safe.
How to Check if Canned Food is Safe
Even if a canned item is far past its date, you can still determine safety by inspecting it carefully:
- Look for damage: Avoid cans that are bulging, leaking, rusty, or severely dented. These can indicate contamination.
- Smell and appearance: After opening, discard any can that has an unusual odor, discoloration, or texture.
- When in doubt, throw it out: Safety should always come first. If something seems off, don’t take risks.
Best Storage Practices for Longer Shelf Life
To maximize the lifespan of canned goods, follow these simple storage tips:
- Store in a cool, dark, and dry place—avoid garages, attics, or near heat sources.
- Keep cans upright to protect the seals.
- Rotate stock: Place newer cans at the back and use older ones first.
- Handle with care: Avoid dropping or denting cans, as this can compromise their safety.
- Refrigerate leftovers properly: Once opened, transfer contents to an airtight container and refrigerate. Never store food in an opened can.
Final Thoughts
“Best By” dates are about quality, not safety. By understanding how long canned foods can truly last, you’ll not only keep your family safe but also cut down on unnecessary food waste. With smart storage and careful inspection, you can confidently enjoy canned goods long after the printed date—saving money and making the most of your pantry.
