Studies have shown that swordfish and other carnivorous fish are at the end of the food chain, so it is easy to concentrate a pollutant called methylmercury. The substance appears naturally or occasionally in the environment. Although methylmercury varies with the environment, it is relatively high in carnivorous fish. The central nervous system of young infants will show specific toxic reactions to this mercury derivative.
