Because of the processing of the oils today, mercury is removed early on. I remember reading that the processes are better than in the past, and it is really the PCBs and dioxins that are problematic.
If you look on iherb, some companies explain what is removed in their products, in detail.
This is a quote from iherbs NatureMade product:
Quote:
†Nature Made Fish Oil supply comes from deep ocean water. Our fish oil is not supplied from farm raised fish. State-of-the-art molecular distillation is used to remove PCBsą, dioxins and furans˛, which guarantees purity and potency. Mercury below 0.1 parts per million.
