Mercury in Fish

Most consumers are aware that mercury (in the form of methylmercury pollution) can accumulate in the flesh of fish. Concentrations high enough to constitute a health risk my be found in some species such as swordfish.

Chen & Williams (2009) surveyed fish consumed in the United states and found that mercury levels declined significantly between 1995 and 2005. However they still recommend that pregnant women and children should not consume high quantities of the species most likely to accumulate mercury, such as swordfish and shark.
