Giant Eagle (at least the one near me) is selling Escolar as cod which makes you quite sick. I have confirmed this and it is happening quite often now according to many online sources. I am not sure if Giant Eagle is to blame or their distributor. The fish looks and tastes identical to cod but the after effects are unmistakable and could only be caused by Escolar. I am not sure how widespread this is, but thought I would pass it along. This fish is also knows at butter fish and is banned in several countries as it is quite potent.
