Monsanto’s own emails and documents reveal a disinformation campaign to hide its weedkiller’s possible links to cancer

Over the past year, evidence of Monsanto’s deceptive efforts to defend the safety of its top-selling Roundup herbicide have been laid bare for all to see. Through three civil trials, the public release of internal corporate communications has revealed conduct that all three juries have found so unethical as to warrant punishing punitive damage awards.

Much attention has been paid to Monsanto conversations in which company scientists casually discuss ghostwriting scientific papers and suppressing science that conflicts with corporate assertions of Roundup’s safety. There has also been public outrage over internal records illustrating cozy relationships with friendly regulators which border on – and possibly cross into – collusion.

But these once-confidential Monsanto documents demonstrate that the deception has gone much deeper. In addition to the manipulation of science and of regulators, the company’s most insidious deceit may be its strategic manipulation of the media, according to the records.
