Canned goods generally last for years past their "best by" date, as long as the can is in good condition.
Here's a more detailed breakdown:
-
"Best By" vs. Expiration Date: It's important to understand that "best by" dates are not the same as expiration dates. "Best by" dates indicate when a product is likely to be at its peak quality in terms of taste and texture. The food is typically still safe to eat after this date.
-
Safety Factors: The primary factors determining the safety of canned goods are:
-
Can Condition: The most critical aspect. Check for:
- Rust
- Dents (especially severe ones)
- Swelling (a sign of potential bacterial growth)
If any of these are present, discard the can.
-
Proper Canning: Commercially canned goods undergo stringent processes to eliminate harmful bacteria, such as Clostridium botulinum. Home-canned goods require meticulous adherence to safe canning procedures to prevent botulism.

How Long Do Canned Goods Really Last? While optimal quality might decline after the "best by" date, canned goods can remain safe to eat for several years if stored properly in a cool, dry place.
-
Signs of Spoilage: Even if a can appears to be in good condition, look for these signs when you open it:
- Foul Odor: An unusual or unpleasant smell.
- Abnormal Appearance: Discoloration or unusual texture.
- Gas Release: A hissing sound upon opening could indicate spoilage.
-
Storage Recommendations: To maximize the shelf life of canned goods:
- Store them in a cool, dry place.
- Avoid storing them in areas with extreme temperature fluctuations.
- After opening, transfer any unused portion to a covered container and refrigerate.
In summary, canned goods can last for an extended period beyond their "best by" date if the can is undamaged and stored properly. Always check for signs of spoilage before consuming.
