Being forced to drink raw milk all day is part of an ancient execution method designed to kill you with your own diarrhea soaking you until you rot alive.
Unfortunately, this is true but they'll also mix it with honey and pour it on you as well. Bugs and rats will then start to eat you alive along with the bacteria. It's called Scaphism.
The veracity of that is a bit debatable though, it's allegedly a Persian practice and the only sources are Greek wartime propaganda intended to paint them as barbarians.
