Sometimes expiration dates refer to when enough plastic from the packaging has decayed into the food material that it might be a problem. Bottled water works that way.
I don't know:
- How much science there is behind the dating
- How much plastic you're consuming in your food anyway and so who cares what's the difference
- Whether that's what's going on with this salt package specifically
But it's not automatically crazy for there to be an expiration date on an immortal product if it comes packaged up in plastic.
Yeah. I feel like they probably just pick some random bullshit, and if people get botulism they look at reducing it, and if they throw away a quarter-million dollars worth of product that expired they look at increasing it, and if neither of those happens then they don't worry about it. I have no knowledge of it but even hearing that they do taste tests is a little surprising to me. But I am cynical.
I did know some people who were once "employed" on a sort of temp job that was excising already-passed expiration dates from a massive number of cans of fish, and then stamping new later dates on them.
