Re: EPA warns of PCBs in farmed salmon, July 31.

In its report on the safety of farmed salmon, the error-prone Environmental Working Group (EWG) revealed only that the average concentration of PCBs in the fish was a small fraction of the U.S. Food and Drug Administration’s established safety limit.

The FDA has set a ceiling of 2,000 parts per billion, but EWG found an average concentration of only 27 parts per billion. The FDA has already affirmed that consumers “should not alter their consumption of salmon” because of EWG’s misleading report.

This group has a long history of using junk science to make the public needlessly fear its food. In this case, a handful of organic food activists is raising red flags over a perfectly safe fish, based on only 10 samples, and without scientific peer review.
