My main beef with the issue (groan) is the complete failure of a documented supply chain. It's not just fraudulent use of horse instead of beef, it's the risk of phenylbutazone, other medication, and the fact no one knows if its a healthy safely slaughtered horse, a knackered drug loaded race horse, or the 6 week old maggot ridden carcass of a horse pulled out of a waterlogged ditch somewhere in Romania. It also puts into question the origin of all supermarket meat and processed meat, not just beef. Hell, no ones tested for cat, dog and rat DNA have they, and although it never made mainstream news, if collagen farmed from executed Chinese prisoner's skin worked its way into the western beauty industry, what happened to the rest of the prisoner? Whilst my local butcher displays the location of the farm, the breed, the day of slaughter and even ear tag number, I must admit I used to buy at supermarkets as well, had the odd bit of comfort food (Fray Bentos pies, ready meals, tins of ravioli and spaghetti) and would enjoy the odd fast food takeaway every now and then. Now I'm having to change my buying and eating habits to remove those altogether.
