No, the only other allergy I have is to shell fish, which obviously has nothing to do with red meat. I was talking with someone the other day and it might be iodine content in the blood. I have no idea if there is any truth to it or not. Tried to google it of course, but got weird results. I am also not sure its the hide because before cleaning the deer, we pick it up, put it in the truck, all that kind of stuff and I have no immediate reaction. It only happens when i get blood on my hands.
