Yanno, I think whether or not pregnancy is involved people should start avoiding these fish ( too bad love fish)... I have never really understood why these warnings are directed at pregnant women only. Appeasing the tuna industry? Yes it is bad for a fetus, but isn't it equally bad for the adults who bioaccumulate this stuff? I've read that it may be a factor in the onset of Alzheimer's disease for instance.

Probably wise to avoid most of the predatory fishes... they have higher mercury from eating up all of the other fish that are consuming mercury (like schools that hang around point sources in the Gulf of Mexico)... that's why the lighter canned tuna is lower in mercury, the fish are smaller, and the steaks and albacore are from larger mature fish that have bioaccumulated for awhile. But the same applies to any predatory fish in coastal waters.
