Scientists criticize IARC for withholding data showing glyphosate herbicide does not cause cancer

|

According to a new Reuters investigation, Aaron Blair, the scientist who led IARC’s [the International Agency for Research on Cancer, a division of the World Health Organization] review panel on glyphosate, had access to data from a large study that strongly suggested that [glyphosate] did not cause cancer after all—but he withheld that data from the [glyphosate] review panel. Weirder still: Blair himself was a senior researcher on that study.

So why on Earth would a scientist fail to mention his own work—and blithely let a powerful agency come to a conclusion that his own data suggested was wrong? IARC told Reuters it’s because Blair’s data wasn’t published yet, and the agency has a policy against taking unpublished data into consideration.

[Michael Eisen, a professor of genetics, genomics, and development at the University of California-Berkeley, founder of the Public Library of Science, and an outspoken advocate of transparency in science, said] that in this particular case, he found IARC’s rule “silly.”

“This is a board of people whose job it is to assess evidence, so they should be able to do that before it’s published,” he said. “The broader issue is that they seem eager to have reached the conclusion that they reached.”
