The AAP authors sent me additional studies that they said bolstered their argument about the dangers of glyphosate, but the research they cited focused on high exposure levels—the kinds of doses one might receive as a farmer who works with the pesticide every day. That’s extremely important data to consider, but it’s not the same as studying exposure to the trace amounts of glyphosate present in children’s food. Caulfield said that he agreed with the authors on the need for rigorous monitoring and research on the risks of herbicide exposure, especially for farmers. But, he said, “the report seems to merge concerns about herbicides as a way of condemning GMOs more broadly.”
