In what world does milk "keep fine in storage"?
(To be fair, I think I'm the only person I know who does this)
Not every milk is UHT but every grocery store offers it.
But what about Costco (or other bulk-only sources), which is, really, the whole point of the thread (and original comment)?
In some cities I've lived, the expiration date of milk was often two or three weeks out. In other cities, it was 10 days maximum.
I think it's because dairies (and cows) are not equally plentiful in every part of the country.
One thing I have noticed is that in the places where regular milk expires in 10 days, the organic milk (which one family member drinks) doesn't expire for a month or more.
only limitation is: infant formula and false advertising (defined in https://www.law.cornell.edu/cfr/text/9/317.8 )
It seems the only places where it's "common" are Italy, Turkey, Switzerland, Germany, Czech Republic, Brazil, Portugal, Spain, France, and Belgium.
