Unpasteurized milk. The USDA and CDC state that it's unsafe, but the only hard fed rule is don't sell it across state lines. Individual states regulate sales within their boundaries.
My wife's family had a dairy farm the first ten years we were married. They took great effort to keep the operation clean, but man are there a lot of flies. The flies on the manure are the same flies hanging around the bulk tank.
Will you get sick if you drink raw milk? Probably not. I've had it plenty, floaties(cream) and all. But, I choose the safer option day-to-day because I think my number would eventually come up.
I don't care if you drink raw milk, just don't make me lose my patience when you clog up my hospital( Is that how you do it Sammy?)
