11 Life is in the blood, and I have given you the blood of animals to sacrifice in place of your own. 12 That's also why I have forbidden you to eat blood.

So it seems to me that they were not to eat the blood because they were to use it to sacrifice on the altar ( singular ? ) to the Old Testament God and that the Old Testament God did not want people to sacrifice the blood to other gods
I have to wonder are the Kikes collecting blood for "goat-demons"
