Dog food plants are inspected, I’m sure by the government, but more importantly by Wal Mart and other big boxes that carry their product. People are nuts about their pets, and dog food plants are probably cleaner than this meat plant.
Some pet food companies buy raw goods from rendering facilities that process animals euthanized at animal shelters. That means that some pet food is made from a variety of meats that humans wouldnt eat, including diseased livestock and cats and dogs containing lethal doses of sodium pentobarbital. In other words, the body of a stray dog killed in a shelter may be ground up into dog food.
