I'm confused....why do you think you CAN get Lyme disease from raw milk?
I think there are lots of diseases you can get from raw milk....TB, listeriosis, salmonella, brucellosis, E. coli, etc., but I have never seen nor am I seeing now through googling anything linking Lyme disease to raw milk. What research do you have?
ETA: this source
says that Lyme disease requires a tick bite for transmission in both humans and cows.
OTOH, this source
says that Lyme spirochetes have been found in breastmilk, so presumably they could be found in cow's milk as well. That raises two questions, first, can infection occur by drinking raw milk with spirochetes, or does it have to be injected directly into the bloodstream, and second, would pasteurization kill the spirochetes.
If I were to drink raw milk, I would want to know that the farmer regularly tests the cows for diseases including Lyme disease. I don't think I'd just buy it from an unknown source, KWIM?
