Some study reports have appeared in which the authors suggest that exposure to glyphosate may lead to an increased incidence of autism. These findings are based on “test tube” studies, making their relevance and ability to predict potential adverse health effects in humans, obscure. Moreover, these studies, as well as numerous others, which investigated various toxicological endpoints, were considered in the recent review of the safety of glyphosate by the EU and were not considered relevant to the assessment of the safety of glyphosate (BfR, 2015). It is also important to note that many authorities believe that the increased incidence of autism may be largely attributable to improved awareness and screening techniques.
