A study conducted by the Food and Drug Administration Agency (FDA) of the United States included bluefish in the list of good seafood choices and prescribed a limit of one serving per week for pregnant women. However, bluefish is known to contain high levels of Polychlorinated Biphenyls (PCB). According to a study conducted by the Maine government, bluefish have shown PCB levels between 200 and 600 ppb. Bluefish also contains toxins such as dioxin and mercury. Hence, it is recommended for expecting mothers to consult their doctors to determine whether they can eat bluefish during the 9 months.
