Some Sushi is not really the fish on the menu i.e. mislabeled according to Boston.com.
By the time the fish appears on diners’ plates, it has undergone a Cinderella-like transformation: the escolar, which can cause digestion problems, is presented as white tuna or albacore – more palatable and pricier fish.
Boston.com writes that the problem with mislabeled tuna and other fish is “endemic” in the area. Given the ease with which fish is shipped around the country and world however, regardless of where you live, you have most likely had some escolar in place of tuna.
While I’ve never heard of escolar, and maybe it is actually better tasting than tuna, the FDA’s warning regarding escolar is enough to make me crave some “Chicken of the Sea”:
…the US Food and Drug Administration advises against the sale of escolar because the fish contains an oil that can cause severe gastrointestinal problems.
Domo Arigato to Boston.com and Sumimasen (or is it Gomennasai?) to those of you who were hoping to enjoy some sushi tonight.
