Yes, Linda! You are right to draw attention to the meat rendering scandal. I give Forgy a home-made and home-cooked blend of beef (human consumption quality) - which I grind in a machine - plus some vegetables and fruit added (mostly from our garden). Personally, I don't give raw meat, because of the risk of worms. I cook it thoroughly. But I understand why some dog lovers prefer to give raw meat for health reasons. What goes into most (not all) commercial pet foods is really worrying.
I am with you 100% about the meat rendering disgrace. The article you cited is about America, but the problem is practically world-wide. The EU has some controls on the practice, but it exists there, too.
