[QUOTE="Quigly, post: 1253950, member: 21929"] You can call me a sucker, but I still buy into the USDA's line that pasteurization kills Johnes. I will admit it likely does not do as well against MAP as it does C. burnetii or M. bovis, but there is likely a significant decline in the number of viable organisms. Some may sneak through in milk samples with a high burden, but I don't know that we can say pasteurization doesn't kill most MAP. I know they found it in milk in grocery stores in Wales, or Scotland, or one of those half countries over there. I think the dairy people in the US were claiming that the high heat short time pasteurization protocol they used there differed from the US or something like that so we shouldn't worry and should all drink a gallon of milk each day. There's probably a little sneaking through, but most of it is likely getting killed. I probably should visit the lit on the topic and make sure I'm not digging myself a hole misremembering things I haven't looked at in a while, but it can wait til tomorrow, or the next day. Additionally, isn't milk pasteurization one of the mainstays of the Johnes prevention program in dairy herds? [/QUOTE]
