FDA 认为除孕妇，奶妈和儿童外，每周吃 14 ounces 含水银平均在 0.5 和低于 0.5 ppm 的鱼和贝类 (Fresh or frozen tuna, Orange roughy, Mahi mahi, Herring, Halibut, Grouper, Catfish, Cod, fresh or frozen Salmon, Canned tuna, Pollock, Flounder or sole etc) ，其中的水银对健康没有影响。
孕妇，奶妈和儿童每周可以吃 12 ounces (about 3 to 4 servings) 含水银远低于 1 ppm 的鱼和贝类。
