I recently had this experience:
Shop Rite sells 15 month old Haagen-Dazs. Saturday, May 16, 2020
... ice cream with "best by" (euphemism for expiration date) November 2019. Yes, from LAST year.
So the November 2019 ice cream was probably produced in June 2018. If it had a creation date almost two years old, would you buy it? And what kind of company would put it on its shelves?
If these dates were properly regulated, they would have such a creation date, which would be much more instructive than a meaningless "best by" date.

Federal legislation is needed for CREATION dates on foods sold. They can also have an expiration date but that would be as superfluous as it currently is.
With a creation date we consumers can make our own decisions.
