In one of the vitamin A articles I found the sentence that
"one ounce of palar bear liver" can kill a man immediately.

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.
