Open shelf life dating of food
Below is a sampling of how some manufacturers code their products so consumers know when the product was packaged. Any other use of these materials without prior written authorization is not very nice and violates the copyright.
For a sampling of how to read product codes, See Below.
Remember, the code stamped on the can is when it was packaged.
We don't recommend keeping canned food for 100 years, but if the can is intact, not dented or bulging, it is edible.
In a well-run supermarket, foods on the shelf will be rotated on a regular basis, so there is continuous turnover.
Many canned products now have a "for best quality use by" date stamped on the top or bottom of the can.
