SeaBreeze, I am not looking either. I have read about this and it sickens and disgusts me that we can be so inhumane to animals.
It is not just our food that is subject to this treatment. Dog food companies regularly get the corpses of animals that were euthanized at the dog pound, or vet clinic, and it is processed into our pet food, labeled as protein, of course.
Even horse and cattle feed has questionable ingredients, unless you buy it from a local granary, and know what is put in the feed.
I am not so sure we were originally designed to be omnivorous, but it has been what man has eaten for centuries. But, up until the last 100 years or so, people raised their own meat, just like they grew their own gardens; and didn't brutalize it when they killed it to eat the meat. Some people, like the American Indian, asked forgiveness for killing the animal, and in that way showed it a final respect.
I have always enjoyed a meal with meat as a part of it; but now, it is hard for me to even walk through the meat department at the grocery, thinking how the animals are treated, and what they were fed, or shot full of (antibiotics, growth hormones, etc.), before they come to us as nice cuts of neatly packaged steaks or hamburger.
Since vegetable protein is actually something that our body can use for re-building itself, better than animal protein; I can't see any reason not to be predominantly vegetarian, and that is what I now mostly do.
