Fish oil supplements are known for their omega 3 fatty acids. Below the surface of waterways, small filter fish ingest polychlorinated biphenyl compounds, or PCBs, that were deposited there decades ago by electrical plants and other polluters. A new lawsuit claims fish oil supplements contain: PCBs, industrial chemicals that were banned back in the 1970s because they cause cancer and birth defects.
People should not be exposed to more than 90 nanograms of this carcinogen a day. But the results of the activists’ tests showed three of the 10; Nature Made Cod Liver Oil, and Now Foods’ Salmon Oil and Double Strength Cod Liver Oil, contained much more than that.
