Tesco,Sainsbury,Morrisons and Waitrose admitted about 2 years ago that they were selling Halal and Kosher meats . They weren't clearly labelled and so people were just picking those meats up and buying them not knowing they were Halal. The supermarkets were then supposed to labeling the Halal meats more clearly but I don't know whether they have done so.
Slaughtering of animals is a horrible way to kill them even if they are stunned first but to hang them up , then slit their throats and let their life's blood drain away is just about the most despicable thing to do to any animal. Halal slaughter is an outdated ,inhumane religious ritual and should NOT be carried out in any country let alone a Christian country like the UK. It's barbaric. Where are the R.S.P.C.A.?
