— All UK meat is traceable back to source by a 4 digit EU code which must be displayed on all packaged meat. Large supermarket chains are allegedly getting away with saying that they don't sell halal by saying - 'it can't be halal, because it's been transported with pork (meaning: and therefore contaminated)... But how was that animal killed for that meat? If the meat code leads back to a halal slaughterhouse then that meat being transported (with the pork) is very likely to be the meat rejected by the inspector in the slaughterhouse often post slaughter as 'unfit for Muslim consumption' - this is known as 'Haram'. The Haram meat is then (allegedly) sold off cheaply to the large supermarket and restaurant chains. So this is a by product of halal slaughter - the reject meat, but the animal has still been slaughtered by the halal method. But - if you are concerned about the meat you buy, there is a brilliant new APP from UK APP called 'Where's this from'. It can't tell you if the meat is halal, but it can tell you what slaughterhouse it has come from. You then search that slaughterhouse name on google and find out if it's halal or not. Unfortunately, as far as ready meals etc. go, there is no way if knowing if your supermarket have used rejected halal meat. I'm still in the early stages of investigating this further and will keep you updated.
