Open Letter from Dr. Christopher Portier, Cancer Expert, on His Review of the Carcinogenicity of Glyphosate European Union Authorities

May 28, 2017

The raw data for the animal cancer studies for glyphosate have been made public, and a reanalysis of these data show eight instances where significant increases in tumor response following glyphosate exposure were identified, but had not been included in previous cancer assessments by either the European authorities or the U.S. EPA. 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.
