As the only diffrence between Halal slaughter and 'ordinary slaughter' is that Halal meat is slaughtered while verses of the Quran are being recited I don't see any diffrence. A 'Halal' slaughter house just has a loudspeaker with a tape loop of recitations from the Quran playing in the background as the animals are being killed. The rest of it is the same 'use a sharp knife , make a deep incision , ensure the jugular vein is cleanly severed, drain all blood. That is standard for any slaughter house , you are hardly likedly to use a blunt knife are you ?.
The simple measure of a tape playing the Quran means that the meat can be sold as Halal with out more expence.
Jewish slaughter for Kosher meat has to be carried out by a trained (Jewish) Kosher slaughter-man under conditions prescribed by the Synagogue in a specific Kosher slaughter house , which is exempt from the regulations ( about stunning the animal first) that other slaughter houses ,including Halal must keep to.
But we don't seem to hear much complaint about that.
