Expiration

The FDA requires a time stamp on products in order to be sold..doesnt matter if it can expire or not

It's not the salt that expires but the plastic. After some time the components of the plastic will deteriorate and create a risk for the consumer. And also geekoverlord is correct.

Sorta. It's a "best before" date, not an actual expiration date. Salt when stored in an air tight container in a cool dark place will last pretty indefinitely. When exposed to moisture or other things it can break down or become unpleasant. You can technically reclaim salt after this has happened, but will likely lose any added iodine etc. So the best before date is really just an estimate of how long the average person using reasonable storage practices has before the salt begins to alter from freshly processed at the factory.

This is the first time its been posted here.

It has been posted here before. But it's been plenty long since the last time it was posted and was acceptable to be reposted.

Maybe I'm on here too much. I seem to keep seeing it. Probably from Facebook too.
