>I am not sure what is different, either new viruses, or american cows are different, or certain people did not develop immunity to certain bacteria in their childhood.
It's H5N1 Avian Influenza[0], which has been linked to[1]:
Globally, as of March 28, there have been 888 cases of H5N1 reported in
humans in 23 countries. Of those 888 cases, 463 were fatal. That represents a
52 percent fatality rate;
I imagine that live H5N1 virus will make raw milk extra tasty and, assuming you're not one of the 52% who will
die from contracting the virus, Bob's your uncle, eh?
