Cancer Expert Calls Glyphosate Assessment “Scientifically Flawed”


Glyphosate Safety Assessment is “Scientifically Flawed”

Dr. Christopher Portier Calls On the European Commission For A Reevaluation After Carcinogenic Findings Were Omitted From European Reviews.

May, 28, 2017

Dr. Christopher Portier wrote an open letter to European Commission President Jean Claude Junker calling for a for a re-evaluation of the carcinogenicity of glyphosate after he reviewed recently released raw data tables for the mouse and rat carcinogenicity studies and found that 8 statistically significant tumor increases were not mentioned in the European Food Safety Agency and the European Chemical Agency assessments.

“Both EFSA and EChA  failed to identify all statistically significant cancer findings in the chronic rodent carcinogenicity studies with glyphosate. “

Dr. Christopher Portier is Former Director US National Center for Environmental Health, Former Director US Agency for Toxic Substances and Disease Registry Former, Associate Director, US National Institute of Environmental Health Sciences and Former Associate Director US National Toxicology Program.

Executive Summary: The European Food Safety Agency (EFSA) and the European Chemical Agency (EChA) have completed their assessments of the carcinogenic potential of glyphosate and concluded that the evidence does not support a classification for glyphosate.  The raw data for the animal cancer studies for glyphosate have been released, and a reanalysis of these data show eight instances where significant increases in tumor response following glyphosate exposure were not included in the assessment by either EFSA or EChA.  This suggests that the evaluations applied to the glyphosate data are scientifically flawed, and any decisions derived from these evaluations will fail to protect public health.  I ask that the evaluations by both EFSA and EChA be repeated for all toxicological endpoints and the data underlying these evaluations be publicly released.

“I found eight [8J significant increases in tumor incidence that do not appear in any of the publications or government evaluations presented by both EFSA and EChA.”
