It clearly states in the video that these "procedures" are accepted by the American food association. The point is, they can not be told on for this because it is accepted in America by what ever administration runs it.
They should get a video of an inspector going in and clearing these so called "American Factories" if they are allowed by the FDA.
Besides, these animals are born within slaughter houses, they are going to have a stuffty life regardless.
Also, I own 3 dogs and a cat. I would care if someone did this stuff to them, but these animals were destined from the start to endure it.
