Sudden Interest in Dated Argentine Research on Glyphosate

10/1/2010

Media reports have recently referenced research on glyphosate first announced last year by a group of Argentine researchers.  Dr. Andrés Carrasco, one of the researchers, previewed the group's findings in articles published in an Argentine newspaper in the Spring of 2009.  Their study, alleging that glyphosate caused malformations in frog and chick embryos, was published in August 2010.

The findings reported by these authors are not surprising given their methodology and unrealistic exposure scenarios.  In fact, using this same methodology over a decade ago, caffeine caused malformations in chick embryos (Kobayashi et al, 1995). Caffeine, in its natural and added forms, is found in coffee, tea, cola beverages, energy drinks, chocolate and even some medicines.   In the same way, the Argentine group's results alleging effects from glyphosate exposure were based on methodologies that are neither relevant for predicting effects on human health nor used by regulatory authorities for that purpose. Regulatory authorities and independent experts around the world agree that glyphosate does not cause adverse reproductive effects in adult animals or birth defects in offspring of these adults exposed to glyphosate, even at very high doses.
