Syngenta has consistently denied any link between paraquat and Parkinson’s, pointing to regulatory reviews in the U.S., Australia and Japan that found no evidence of causality.

Well I don’t know about the US or Japan, but I can trust my government to do the right thing.

The chief executive confirmed the science underpinning the regulator’s decision rests largely on an earlier report prepared for the APVMA in 2016, which also assessed mice studies linking paraquat to Parkinson’s disease.

That report acknowledged Dr Cory-Slechta and her co-authors’ findings from 2002 that paraquat caused hallmarks of Parkinson’s in mice that were injected with the chemical.

But the 2016 report’s authors ultimately dismissed those findings, on the basis that an unpublished paper, funded by Syngenta, could not reproduce them.
