Many people mistakenly discard canned goods simply because the “best by” or “best before” date has passed. But these dates aren’t hard expiration dates—they’re guidelines for peak quality, not safety. Learning to read and interpret these labels can help you reduce waste and save money, while still enjoying safe and nutritious food.
What Does “Best By” Mean?
The “best by” or “best before” date is the manufacturer’s estimate of when the product will taste its best. For canned goods like corn, green beans, and tuna, this means the food is still safe to eat well after this date, provided it’s been stored properly.
Canned Foods Beyond Their “Best By” Dates
1. Canned Corn
- Shelf Life: Safe to consume 1-2 years past the “best by” date.
- Quality: Over time, the texture and flavor may diminish slightly.
- Safety Check: Inspect the can for rust, dents, bulges, or leaks. If the can is compromised, do not use it.
2. Canned Green Beans
- Shelf Life: Typically safe for 1-2 years beyond the date.
- Quality: May lose some texture and flavor as time goes on.
- Safety Check: As with corn, look for any damage to the can before use. If there’s any doubt, discard it.
3. Canned Tuna
- Shelf Life: Safe for 3-5 years past the “best by” date when stored properly.
- Quality: The flavor and texture may degrade, but the tuna is still safe if the can is intact.
- Safety Check: Before consuming, look for unusual smells, discoloration, or an odd texture. If anything seems off, discard it.
Storage Tips to Maximize Shelf Life
Proper storage is crucial to extending the life of canned foods:
- Cool, Dry Place: Keep cans away from direct sunlight and temperature extremes.
- Upright Position: Store cans upright to protect the seals.
- Rotate Stock: Place newer cans at the back and older ones at the front for better usage tracking.
- Handle with Care: Avoid denting or dropping cans, as damage can compromise their safety.
- Refrigerate Leftovers: After opening, transfer unused food into a sealed container and refrigerate it promptly.
Signs of Spoiled Canned Foods
Even if the “best by” date hasn’t passed, discard canned goods showing any of these signs:
- Bulging or swollen cans
- Rust or corrosion
- Leaks
- Unpleasant odors upon opening
- Odd textures or discoloration
Final Thoughts
“Best by” dates on canned foods are more about quality than safety. By storing your canned goods correctly and inspecting them for signs of spoilage, you can safely use them well past their labeled dates. Properly handling and understanding these dates not only helps reduce food waste but also saves money and resources. So next time, think twice before tossing that can!
