I shouldn't be trying to post this early. I'm definitely not awake yet. When the inflation is on the cow's teat, and the milk swirls, in between each pulse there's a relaxation, which can cause the milk to backwash slightly into the teat orifice. So if there's any bacteria on the outside of the teat, the milk picks it up, then it backwashes back inside momentarily, a bad bug or two might hang on and stay inside. That could happen with every pulse/release of the milker. That's what I was trying to say. I'm going to get a fresh cup of coffee now and see if I can't get the rest of my brain in gear.
