We were warned time and again this would happen.
Our uncle had a dairy when we were growing up. He gave all the relatives milk. Over half of my cousins tested positive for TB—linked back directly to the cow herd. We were dairy farmers also, but faithfully pasteurized our milk. We were fine. Wonder if the Amish test their herds for TB? Probably not. Just a heads up for drinking unpasteurized, untested milk.
