Actually. These guys are scary
Environmental Working Group
SCARE: In March 2004 the Environmental Working Group (EWG) held a press conference to proclaim that "unsafe" mercury levels in fish were endangering pregnant women and their children. That same month, in cooperation with the political group MoveOn.org, EWG produced and distributed a television advertisement claiming that mercury "gets into the air, the water, and then into the fish we eat, causing brain damage in children." The spot warned that without political changes in Washington, children will "go on eating mercury in their tuna, risking brain damage."
FACT: The 2004 EWG press event and the subsequent TV ads were developed and organized by Environmental Media Services, an advocacy arm of the Washington, DC public relations firm Fenton Communications. This firm used the phony 1989 "Alar-on-apples" food scare to make money for the Natural Resources Defense Council, one of its paying clients.
SCARE: EWG operates an online "tuna calculator" that needlessly scares Americans (particularly women of childbearing age) away from eating tuna. EWG has promoted its calculator in newspaper and magazine articles, and on daytime talk shows viewed disproportionately by women.
FACT: There is no scientific consensus to support the opinion that mercury, in the tiny levels that naturally occur in tuna fish, causes brain damage. EWG purposely confused the Environmental Protection Agency's mercury "Reference Dose" with a level that might actually cause harm. But that Reference Dose is ten times lower than the real harm threshold. Dr. David Acheson, the Food and Drug Administration's chief medical officer, told The Washington Times: "We know there will be people above the Reference Dose, above the tenfold safety factor. But not far above it. They will be in the zone of safety."
SCARE: In 2001 EWG issued a report called "Brain Food," claiming that pregnant women should not eat "any quantity" of 13 types of fish, and strictly limit consumption of 10 others, including canned tuna.
FACT: The Environmental Working Group's "tuna calculator" conveniently uses the EPA's mercury "Reference Dose" as its measuring stick. EWG undoubtedly knows that the EPA standard has a built-in ten-fold margin of safety, but the group continues to mislead Americans by claiming that this Reference Dose defines what is "safe" and "unsafe." This may be one reason why some in Washington refer to EWG as the "Environmental Worrying Group."

SCARE: In December 2004, EWG claimed publicly that mercury in fish was putting American children at increased risk of developing autism.
FACT: Many studies have shown no link between mercury (from both fish and routine immunizations) and autism, including a comprehensive 2004 report from a U.S. Institute of Medicine committee. One member of that committee, Johns Hopkins Medical School professor Dr. Steven Goodman, told the Reuters News Service that EWG's claim about mercury and autism "doesn't remotely establish what is cause and what is effect."
