Halal slaughter makes for very tough meat. I grew up on a farm and we would humanely kill a cow by calmly walking up to the animal in its feedlot and shooting it in the head with a .22 rifle. The animal would lose consciousness immediately and before its heart stopped beating I would cut its throat to bleed out the animal. The animal was then skinned, gutted quartered and hung to cure. 28 days in a refrigerator before it was cut into serving portions. The tough bits were ground into hamburger but the rest became roasts or steaks. The meat was so tender you could cut it with a fork and the flavor was wonderful.

Go fuck a goat 😂

You cannot drain all the blood out of an animal being slaughtered. Try as you may blood will remain in the capillaries therefore deep in the tissues. Complete cooking will eliminate any bacteria that may be present.
