Killer

Looks like what happens after a sand fly bite. It happens to people too, not all sand flys, but some, carry a disease that rots cartilage, affecting the nose and other parts of the body. It happens to humans when an infected fly bites us too. I'm willing to be money on it. Im sure as the man above stated, cooking the meat more than likely kills the disease. But I indeed believe that this is the result of an unlucky elk and a hungry sand fly.
