and why do they use dating that most people don’t understand as an expiration date ?
Are not expiration dates on food a requirement for public safety ?

I think you are talking about "Julian" dating.

Many applications (especially mainframe systems) store dates in the Julian format, which is a 5 digit number, consisting of a 2 digit year and a 3 digit day-of-year number. For example, 24-August-1999 is stored as 99236, since 24-August is the 236th day of the year.

I suppose they would say that they use it because it is more easily computerized. It may be that they really don’t want the consumer to be able to easily read it and are putting it on there more for the benefit of the retailer.

Perhaps the most surprising thing about expiration dating is that dating is not required by US federal law for any foods except infant formula and baby foods. Not only are expiration dates mandatory for these products, but these products must actually withdrawn by their expiration date. When it comes to dairy products, laws vary by state, but for all other foods everywhere, slapping an expiration date on the product is decided by only one entity: the manufacturer of that product.
