It comes down to "Maximizing profit by turning undesirable or inaccessible meat into nuggets in a potentially dangerous process."

I don't agree that is a particularly good description of the process. They are making the meat accessible, it isn't undesirable to begin with.

There could be some occupational hazard, I don't know. It seems clear enough that it isn't much of a food hazard (we've been eating it for decades).
