See below: Yes, mercury (Hg) is dangerous. Any amount but it is dose-dependent. Some fish like tuna do contain Hg but it all depends on what type (species) of fish you eat, where it is caught, and how much you eat. If you are concerned, Hg levels can be checked by a blood test.

Maybe: how much?: Depends on whether you're eating ahi steaks or sushi. Estimate the ounces you eat and your weight. Check out the tuna calculator at environmental working group website www.Ewg/tunacalculator.
