I grew up on a dairy farm and we drank raw milk every day. I can remember my sisters bringing the milk pitcher to the barn and dipping into the bulk tank of raw milk every morning or so. No one got sick and no one died. We even made butter at home from it after separating the cream. But pasteurization is a good thing for all you urbane urbanites out there. It increases the shelf life and safety for consumption. Plus it reduces number of small dairies near population centers that used to exist. Dairies can be 100+ miles away now. After all, you wouldn't want to be exposed to the smell of cow shit right?
Raw milk does taste very different from store bought pasteurized milk, (whole milk ain't whole). And like shelf stable milk, I doubt anyone of you would like drinking it.
