I bet in Cuba none of the milk is pasteurized, but you have to pay a kings ransom for the right to put a stamp on it saying that it is. As for it being recent, it’s named after Pasteur, and he died in 1895.
There are newer more effective processes than pasteurization nowadays. there is milk that can be non-refrigerated as long as it isn’t opened. It can sit on a shelf in the grocery store for 6 months or more before expiring. The milk and dairy lobby won’t use it for obvious reasons..............
