I skimmed the video, and it honestly isn't that disturbing.
Try watching a video of a dog being skinned alive, and then left to suffer afterwards then get back to me.
With the people responsible all having fun and joking while doing it mind you.

Brovo has a point in that we really should not be surprised the quality of our food gets bad when we treat it bad. It make sense both from a health and moral stand point to treat these animals better.

That happens in the film.
