BUENOS AIRES, Argentina – An Argentine neuroscientist who became one of the Monsanto Company's most difficult public relations problems has died.
Argentina's national science council announced Saturday that its past president Andres Carrasco has died. He was 67 and had been in declining health.
Carrasco was an expert in embryonic development whose 2010 study challenged regulators to re-examine glyphosate. Sold by Monsanto as Roundup, it's widely used around the world and has been labeled safe if applied properly. But relatively few countries enforce pesticide rules, and people are increasingly exposed.
Carrasco found that very small amounts can cause neurological damage in chicken and frog embryos that are similar to human birth defects found in farming communities.
Monsanto challenged Carrasco's embryo tests as unreliable and irrelevant for assessing risk to humans.
