More Pavement for the Road to Hell

From TCS:

In 2003, something called the Environmental Working Group claimed to have evidence that the farm-raised salmon eaten regularly by millions of Americans contains high levels of PCBs. PCBs were identified in the press coverage as a "toxin," "probable human carcinogen," or "a cause of cancer and nervous system damage."

These reports were grossly misleading. At levels of environmental exposure, PCBs have not been shown to cause cancer or any other disease in humans. The "study," which was based on a sample of only ten fish, was condemned by genuine experts at a variety of institutions, including the Harvard School of Public Health, the U.S. Food and Drug Administration, and the highly respected American Council on Science and Health. Unfortunately, the criticisms came only after EWG's report had generated national media coverage, and received little attention from the media.

On its website, the EWG makes no pretense about its possessing scientific credentials or expertise, and its president once admitted to a journalist that there was not a single physician or scientist on its staff.

They just don't care if they are wrong
