The Maine Department of Inland Fisheries and Wildlife and the State Bureau of Health recommend that the liver and kidneys of moose not be eaten because of possible contamination with the heavy metal cadmium. Also, recent studies have shown smaller amounts of cadmium in liver tissues from Maine deer, and deer, elk and antelope from other States. Maine health officials recommend that deer liver consumption be limited to 0.8 pounds in one sitting and 1 to 1-1/3 pounds per week. Human symptoms of acute cadmium poisoning include severe nausea, vomiting, diarrhea, muscle cramps and salivation. There is no known health risk from eating moose meat or deer meat.
