I think nobody would ever have the opportunity ever to taste polar bears. What about Halibut liver oil? It might be wise not to eat a whole ounce of this, if the numbers above are correct. Ah btw: humans method of detoxifying vitamin A is to transport and store it in the liver. Human liver was listed at 550 (per gm). Humans can store up to two years of vitamin A needs in the liver. If this is full... It should better not - you might feel it in the bones. In the case you ate carotenes above the storage limit, skin and eyeballs turn yellow. Amadeus
