You can go to your local farmer. They usually don’t bother selling you some milk. Bring your own bottle for them to fill it up. Also, its usually much cheaper than everything you can buy elsewhere. If you want to be sure you don’t get sick you can cook the milk(but this causes a loss in taste), but you can also drink it without cooling it. You might get sick the first (few) times, but you will get used to it and won’t get sick from drinking raw milk.
