The livers of polar bears, walruses, bearded seals, moose, and huskies can contain very high levels of preformed vitamin A,[3] and their consumption has led to vitamin A poisoning (hypervitaminosis A) according to several anecdotal reports. The Inuit will not eat the liver of polar bears or bearded seals. It has been estimated that consumption of 500 grams of polar bear liver would result in a toxic dose for a human.[3] Russian sailor Alexander Konrad, who accompanied explorer Valerian Albanov in a tragic ordeal over the Arctic ice in 1912, wrote about the awful effects of consuming polar bear liver. Also, in 1913, Antarctic explorers on the Far Eastern Party Douglas Mawson and Xavier Mertz were believed to have been poisoned, the latter fatally, from eating husky liver, though this has been contested recently.
