“You might assume that livestock with cancer or obvious infection would be rejected for all consumption. Not so. The part considered diseased (such as the abscess or tumor) is cut out, but the rest of the sick animal goes right on into human food. Guess where the abscess or tumor goes? Into pet food.”

“•Growth-promoting drugs and hormones. Farm animals are routinely given drugs (antibiotics) and hormones to hasten growth or to prevent health issues from the conditions in which they live. “Today, there are six anabolic steroids given, in various combinations, to nearly all animals entering conventional beef feedlots in the U.S. and Canada: three natural steroids (estradiol, testosterone, and progesterone), and three synthetic hormones (the estrogen compound zeranol, the androgen trenbolone acetate, and the progestin melengestrol acetate). Anabolic steroids are typically used in combinations. Measurable levels of all the above growth-promoting hormones are found at slaughter in the muscle, fat, liver, kidneys and other organ meats. The Food and Drug Administration has set ‘acceptable daily intakes’ (ADIs) for these animal drugs.”6 It is very likely these are affecting dogs and cats as well as people.”
