I had a relative once who had a tumor that had hair and teeth in it. I'm really not so sure the contents of a tumor is necessarily relevant..

I also wonder if any issues with red meat is more related to the hormones and antibiotics that many of them get.

I know my horse wormer says not to use it on animals destined to be food.

It seems to me though, that if we weren't supposed to eat it, it wouldn't taste good.

PS: Did you notice at :06 it says Kirin and Pharma present?
