I absolutely love foie gras, and was kind of aware that the ducks are force fed to produce such a large liver, but have only recently thought more about this and looked it up (mostly cuz I found some at a local market!).
The conditions are horrifying (read about caged ducks who can't even move much/bloody and inflamed rears/bloated legs/bleeding to death from the tube punctures), etc etc. And then something about increased amyloid fibrils from eating it? That is scary, but it makes sense since this would be super diseased-liver--one that is 10x a normal one apparently.
If we try not to eat liver from CAFO animals, why would foie gras be ok? From this viewpoint it would be the absolute worse thing to eat coming from essentially obese, nonactive ducks with liver and other chronic diseases.
Baah, I am sad now. I don't think I can eat any more of this happily :(
