Final Notice of Objection to Re-evaluation Decision RVD2017-01, Glyphosate, April 28, 2017

The Canadian Association of Physicians for the Environment and other organizations are calling for an independent review of the PMRA's glyphosate re-evaluation decision (RVD2017-01). They argue that internal Monsanto documents, revealed during California litigation, show the company ghostwrote scientific studies and suppressed evidence of cancer risks—studies that the PMRA relied upon for its determination that glyphosate is unlikely to pose a human cancer risk. The authors also claim the PMRA failed to consider evidence regarding monarch decline, microbiomes, and the inefficiency of buffer zones as risk management strategies.

• Litigation in California revealed internal Monsanto documents suggesting the company knew for decades that glyphosate and Roundup could cause cancer, leading to a jury finding that the company acted with "malice or oppression."
• Evidence from the "Monsanto Papers" indicates that Monsanto scientists ghostwrote or edited several studies that the PMRA used in its re-evaluation decision, including works by Kier and Kirkland (2013), Greim et al. (2015), and Williams GM et al. (2016).
• The journal Critical Reviews in Toxicology issued an Expression of Concern regarding five articles referenced by the PMRA, with subsequent corrigenda for three articles disclosing previously omitted contributions and competing interests.
• The authors allege the PMRA's re-evaluation was deficient because it failed to consider evidence regarding glyphosate's impact on monarch decline, human and soil microbiomes, cancer risks, and the mobilization of cadmium in grains.
