Fish have extremely high levels of chemicals such as arsenic, mercury, PCBs, DDT, dioxins, and lead in their flesh and fat. You may even get industrial-strength fire retardant with that catch of the day. The chemical residue found in salmon flesh can be as much as 9 million times that of the water in which they live.
