What you are seeing is cutaneous fibroma. They are caused from a virus. They are hairless tumors found on the skin of deer. They are usually temporary. Problems rarely occur from them, but an occasional animal will develop massive tumors that may interfere with sight, breathing, eating, or walking.
Transmission is thought to occur from biting insects and possibly through direct contact. There is no danger from deer spreading the warts to farm animals.
Human infections have not been reported. Only large tumors with a secondary bacterial infection would cause the meat to be unfit for consumption.
We see these every year, and are not considered important to deer populations.
