Unpasteurized milk contains benign bacteria. For that and other reasons, it is better for your health than pasteurized milk.
BUT. That assumes that you live in the country and have access to a dairy farmer you can TRUST. Otherwise you can very easily get a bacterial infection that is not benign.
It’s impossible to trust factory farms or big milk distributors. There are too many ways for infection to sneak in, and in most cases the supply chain is too long for the milk to be really fresh by the time it reaches the supermarket.
So, unfortunately, the answer is that you can and should drink fresh milk if you have a neighboring farmer or friend whom you can trust.
And fire engines are rushing, so they are red too...
You appear to lack understanding of the raw milk industry. The biggest raw daries are actually the most dependable. It's the climate in the area of the dairy that makes the difference; a cool, marine climate is best for milk production, but the run-of-the- mill commercial dairies prefer the mega-hot California central valley, because they can get more production. Bad choice!
