Dairy products are not made from “old rotten milk”; they are made with fresh milk and sanitized equipment. Yes, the final product is fermented, sour, mouldy, whatever – but it was made that way with particular organisms.

The milk in your fridge is old and basically contaminated by a variety of undesirable moulds and bacteria.
