Addressing the safety of postanesthesia euthanasia for scavengers

The article “Use of potassium chloride for low-residue euthanasia of anesthetized California sea lions (Zalophus californianus) and northern elephant seals (Mirounga angustirostris) with life-threatening injury or disease” by Witmer et al 1 addresses an important aspect of euthanasia. In the case of wild species, or animals that must be humanely euthanized in areas where rendering facilities do not exist, options other than barbiturates need to be available. This paper clearly demonstrates the effectiveness of potassium chloride as one of these choices. An additional important issue is the
