Sources for NRDC's guide: The data for this guide to mercury in fish comes from two federal agencies: the Food and Drug Administration, which tests fish for mercury, and the Environmental Protection Agency, which determines mercury levels that it considers safe for women of childbearing age.
High mercury: More than 0.3 parts per million
