Popular brands of fish oil dietary supplements contain unsafe and illegal levels of cancer-causing PCBs, charges a lawsuit filed by environmentalists in California.
The plaintiffs say their initial testing of the products found PCB levels ranging from 12 nanograms to 850 nanograms per recommended dose, CBS News reported.
The lawsuit by two citizen environmentalists and the Mateel Environmental Justice Foundation says the fish oil products violate California's Proposition 65, which requires manufacturers to warn consumers about all chemical exposures.
The eight supplement makers or distributors named in the lawsuit are: CVS Pharmacy, Rite Aid, General Nutrition Corp., Solgar, Twinlab, Now Health, Omega Protein, and Pharmavite, CBS News reported.
