In its report on the safety of farmed salmon, the error-prone Environmental Working Group revealed only that the average concentration of polychlorinated biphenyls in the fish was a small fraction of the Food and Drug Administration’s established safety limit (“Farmed salmon heavy in chemicals, U.S. group says,” July 30).

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 Environmental “Worry” Group has a long history of using junk science to make the public needlessly fear its food, for the purpose of steering Americans toward more expensive organic (or in this case, “wild”) options that aren’t any safer or healthier to eat. EWG’s work has been rightly criticized in the past by officials from the FDA, Environmental Protection Agency and the National Institutes of Health.

In this case, a handful of organic food activists are raising red flags over a perfectly safe fish, based on only 10 samples and without scientific peer-review. That’s what you get from an organization that has admitted to having no doctors or scientists on its staff.
