Very interesting, and thank you for those links. I read through in particular the 2013 Farouk paper. He refers to many studies, but mainly I think a 1994 study by Grandin, and later work by Rosen and by Zivotofsky, which others have also referenced.
A fair summary of his whole article, I think, would be that his focus is on showing the value of stunning for Halal; but that he recognises that this is no help with Kosher. His suggestion there is that we should investigate food grade local anaesthetics.
He summarises “the welfare issues during slaughter without stunning” as being three main issues: “the stress of restraint, whether the cut is painful, and whether the animals experience undue distress whilst it is bleeding [to death] such as the aspiration of blood into the lungs”.
He summarises research that shows on the first point that the Kosher cut can be painless and that the animal may become unconscious very quickly. He concludes, I think, that concerns remain around pre-slaughter restraint, the aspiration of blood into the lungs while dying for larger animals, and varying levels of expertise which may affect whether all cuts are painless. Rosen, writing in 2004, takes a much firmer line and concludes that Kosher is a humane method of slaughter. However, I can’t get into the RVA papers online as we are clearly too tight to have an institutional subscription to it (roll on open access!) so haven’t been able to read it.
Farouk looks at the research questioning whether stunning is humane, but he seems not to agree with it: “There is enough evidence to conclude that head-only electrical stunning does not kill the animal before the animal is slaughtered and the procedure is painless to the animal both at its initiation and whilst the animal is unconscious before slaughter. Therefore, it is the opinion of this author that pre-slaughter stunning using head-only electrical stunning is an acceptable method to meet the requirements of industrial processing of halal meat.”
Both the RSPCA and Compassion in World Farming meanwhile maintain their line that they would like to ban non-stunned slaughter. They discuss the period around slaughter as well as the cut itself, in their explanation.
I am not sure where that leaves me. I do know that there is much worse stuff happening in farming of meat. Transportation of animals is a more serious issue, and so is low-welfare farming. In the end, if you are going to kill a big animal, or rather, lots of big animals in an industrial process, it’s going to be very difficult to do that with no fear or pain. I am told by my butcher that the meat I eat is from local farms, humanely reared, and humanely slaughtered. I am sure if I observed even the most humane slaughter I would be traumatised: I cried for days after putting my cat down.
I just don’t what to think. I am probably a closet vegetarian (my family were all vegetarian when I wa growing up) ; but I do believe in supporting compassionate farming: I just wish I could reliably identify it.
You have made me think and re-examine my views: thank you. I’m not sure I am convinced yet about non-stun slaughter, but I can see that ppl who are convinced do have some grounds for that.
