When you pasteurize milk, you also wipe out all of the flora in the milk. So, there's no bacteria in pasteurized milk, which can be a good thing if there are harmful bacteria in raw milk, which happens very, very rarely, but it's often a bad thing because there's nothing in the milk. There's no organisms. And so, if anything contaminates a pasteurized milk, it's going to go crazy. It's like an augur plate in a science lab.
