Prions.
No, it is not safe, the microorganism (B. anhracis) is secreted in the milk of animal infected with anthrax. You can acquire the disease by drinking this milk.
Most likely not; the odds are slim.
A microorganism the sound a cow makes
There is no such thing as "cow disease" unless you are referring to MAD cow disease, which is something else entirely.
It's not sad cow disease, it's MAD cow disease. Its a brain disease that can cause irrational behavior in cows.
At one time, cattle were fed the unwanted parts of ground up sheep. Some of those cows became infected with mad cow disease. Mad cow disease spread to humans. Cattle were also fed parts of ground up cow parts, cows eating ground up cattle were infected with that disease. The breakthrough came in New Guinea. There, women and children would eat the brains of dead people. Men would not. Women and children would catch a disease similar to mad cow disease. Men would not. That made it obvious that the disease came from something common to women and children and not to men. Since they behaved the same as nearby groups except for eating the brains of dead people, that had to be the difference. The only difference in the brains of the dead people with mad cow disease and those without mad cow disease was the prions. This was then tested in England where mad cow disease was common. The only difference between cows with mad cow disease and those without mad cow disease were the same prions. The people with mad cow disease had the same prions in their brains.
Both are just likely to be affected as the other.
We are aware of mad cow disease
No. It is only if you ate the bone marrow, eyes, or brains/spinal column of an infected animal that you would very likely get CJD (human version of mad cow disease).
Typically a cow with Johne's Disease (which is a disease where a cow has chronic diarrhea) is considered safe to be slaughtered for food.
She had Bright's disease and Mad Cow disease.
People do not get Mad Cow Disease. No human can get mad cow disease but humans can be infected by eating meat from a contaminated cow that has mad cow disease. The disease in people that has been associated with humans is called variant Creutzfeldt Jakob disease (vCJD) that is also a progressive fatal neurological disease.
