Mercury exposure during pregnancy can interfere with the normal embryonic nervous system development, resulting in cognitive (brain) impairment of the child.
Explanation:
Large, predatory fish such as shark, sword fish, king mackerel, tilefish, marlin, orange roughy and bigeye tuna are recommended to be avoided during pregnancy because they may have high concentrations of <em>methylmercury. </em>
