Just One Small Problem With This Major Report on GMO Safety

Researchers allege undisclosed conflicts of interest on a National Academies of Sciences panel.

About a year ago, the prestigious National Academies of Sciences, Engineering and Medicine produced a 584-page report assessing the health, environmental, and agronomic impact of genetically modified crops. The conclusion: GMOs have so far proved to be neither a disaster nor a triumph. They haven't been shown to pose a threat to human health, as some critics have argued they do; but they also haven't discernibly raised crop yields, as some boosters insist they have.

Not surprisingly, the report did little to "end the highly polarized dispute over biotech crops," concluded New York Times reporter Andrew Martin in an article just after the report's release. He added that both sides of the debate "pointed approvingly to findings that buttressed their viewpoint and criticized those that did not."

And a new paper, published in the peer-reviewed journal PLOS-One, ups the temperature of that long-simmering debate. The authors—Sheldon Krimsky, a professor in the Department of Urban and Environmental Policy and Planning at Tufts, and Tim Schwab...
