According to the New York Times http://www.nytimes.com/2011/05/27/sci... Tests Reveal Mislabeling of Fish
Something to watch out for.
I don't see how they could mislabel salmon, trout, flounder or bluefish. And mako shark fillet being passed off as swordfish doesn't really affect anyone reading this board. But catfish passing as grouper does. And it says they're selling some other species as cod.
