Inside a dog food processing plant?

Since so few people really know what is involved in making human foods most people would have no understanding if what they see in pet food manufacturing is "normal" or not. Most people have an idyllic vision of how pet food (and their food) should be made but not what is practical and safe.

Most people would likely be unhappy (even shocked) by what they see outside and inside a meat processing plant (even a good one) unless they have done their own slaughtering.
