Many people take fish oil to get omega-3. (I get mine from flaxseed oil.) Fish contain PCBs, therefore fish oil does. How much? More than we’re told. A lawsuit has been filed about this :
Mateel Justice Foundation, in conjunction with two individual plaintiffs, brought a lawsuit against six fish oil manufacturers and two retailers for labeling violations of the California Safe Drinking Water and Toxic Enforcement Act, also known as Proposition 65. Filed March 2 in Superior Court of San Francisco, the suit alleges several fish oil products sold in California failed to include label warnings for levels of PCBs (polychlorinated biphenyl compounds) found in the products by testing initiated by the plaintiffs . . . Named as defendants in the suit were two retailersCVS Pharmacy Inc. and Rite Aid Corp.and six manufacturersGeneral Nutrition Corp. (GNC); NOW Health Group Inc.; Omega Protein Inc.; Pharmavite LLC (Nature Made brand); Solgar Inc.; and Twinlab Corp. . . . The plaintiffs conducted testing on 10 products produced or sold by the defendants, looking at all 209 known PCB compounds . . . Many fish oil companies test for as few as seven such compounds.

Thanks to Dev Rana. The plaintiffs plan to post testing results here (I have been unable to reach this site).
