The aim of this study was to assess the teratogenicity of the herbicide glyphosate-Roundup® (as commercialized in Brazil) to Wistar rats. Dams were treated orally with water or 500, 750 or 1000 mg/kg glyphosate from day 6 to 15 of pregnancy. Cesarean sections were performed on day 21 of pregnancy, and number of corpora lutea, implantation sites, living and dead fetuses, and resorptions were recorded. Weight and gender of the fetuses were determined, and fetuses were examined for external malformations and skeletal alterations. The organs of the dams were removed and weighed. Results showed a 50% mortality rate for dams treated with 1000 mg/kg glyphosate. Skeletal alterations were observed in 15.4, 33.1, 42.0 and 57.3% of fetuses from the control, 500, 750 and 1000 mg/kg glyphosate groups, respectively. We may conclude that glyphosate-Roundup® is toxic to the dams and induces developmental retardation of the fetal skeleton.

The NEW YORK TIMES says they don't.

The aerial fumigation cycle causes chemical pollution affecting humans, animals and vegetation destroying the livelihoods of peasant and indigenous communities, which leads to forced migration. The displaced move further into the rainforest accelerating the pace of deforestation. The slashed and burned plots are planted with coca or poppy for illicit cultivation. The new plots are eventually fumigated and the cycle starts all over again, exacerbating the on-going armed conflict.
