should i eat this fish?

Use this handy widget from Fish2Fork to quickly assess if that piece of bluefin tuna should go anywhere near your mouth. (Answer: NO!)

[Update: Fish2Fork no longer offers their widget, but they DO have some useful Fish Facts and a good restaurant rating system that might still be helpful to you. In the meantime, the Monterrey Bay Aquarium's Seafood Watch can steer you in the right direction when deciding what fish to eat.]
