I recently learned that my old mounted deer is very likely contaminated with arsenic. (Completely my fault for not researching more before I brought him home) I have since removed him from my bedroom and put him in my shed

Would he be ok in there or is it better to completely dispose of him? It is not temperature controlled

Also could I remove his antlers at all to save them due to them not being in contact with the skin or is he a lost cause?
