Shrimp has been hovering near the bottom of the list of things I will eat for a while. Unless you make a point to get it wild, chances are very good it has been raised in a crowded pond and treated with loads of antibiotics. Factor in its mammoth carbon footprint, and the fact that many of the developing world’s mangroves have been displaced in recent years to make room for shrimp farms, and my appetite for these crustaceans all but disappears.

Now we can add labor abuse to shrimp’s laundry list of problems.
