It is relevant. The quality of the food chain and regulations where you live play a huge role in that particular society's feel about raw products.

OK, you got a point there.

For the other part, you can trust me, that in a refrigerator milk will get bad after 3-4 days. If you cool it at about 2-3°C it is good for longer time(obviously), but I can't tell how long exactly, because the milk never gets that old. As for Quality its quite interesting, that you make assumptions about it without knowing anything. I can assure you, that the milk has good quality. It gets tested every 2 days in terms of fat, germs, protein, and SCC and all of those parameters are always good.
