Even If the meat is “Zabiha”, it wouldn’t change the fact that the animal has been fed with Haram things before it got slaughtered. Which would pretty much make the meat Haram for us Muslims, yeah?
We all know how the mad cow disease came into life, don’t we?
The governments of the countries where most of the cow meat comes from allow the industries to feed their cows with fodder made out of PORK, cow fat, blood, and sometimes even waste of other animals. So yeah, bon appétit.
If you want to eat Halal Zabiha meat, get it from your local Muslim butcher.
