Weed killer, trust thriller
Decades-old study on common weed killer retracted
Ghostwritten? Roundup safety study axed; commenters say trust is toast
TLDR: A key paper calling glyphosate safe was retracted over alleged Monsanto influence, but Health Canada says approvals stay, citing 1,300 studies. Comments split between “we’ve been misled” and “one paper isn’t science,” with memes and calls for a moratorium fueling a trust-and-transparency showdown.
Comment sections lit up after a 25-year-old study saying Roundup’s ingredient glyphosate is safe got yanked for alleged ghostwriting and undisclosed payments. Health Canada replied, essentially, “we checked,” pointing to 1,300+ studies and monitoring that finds human levels 1,000× below concern, so approvals stand until 2032. Activists fired back, calling for a moratorium and a fast-track review.
The vibe split: skeptics cried “Have we been lied to all along?”, accusing “regulatory capture,” while pragmatists argued science isn’t one paper, noting global regulators still say glyphosate isn’t a cancer risk when used correctly. Ghostwriting claims fueled memes about “Monsantopedia” and quips that the study was “Roundup-Ready” for peer review. Lawn dads posted immaculate yard pics captioned “Worth it?”, and foodies nervously joked about breakfast cereal.
One commenter went existential, urging everyone to “allow an ember of self doubt.” Another dropped a link to the previous thread like a mic drop. Bayer insists the products are safe; Health Canada won’t budge. The community’s verdict? Trust is the real weed here—and it’s spreading.
Key Points
- •Regulatory Toxicology and Pharmacology retracted a 2000 review on glyphosate safety, citing undisclosed Monsanto involvement and reliance on unpublished studies.
- •Health Canada says the retraction does not change its 2017 conclusion that glyphosate is unlikely to pose a human cancer risk and maintains approval until 2032.
- •Health Canada’s re-evaluation included more than 1,300 studies and independent assessment of primary data; human glyphosate levels monitored are 1,000x below screening thresholds.
- •Environmental groups are calling for a moratorium and expedited special review of glyphosate in Canada.
- •Glyphosate is the most widely used pesticide in Canada, with ~50 million kg sold annually; Bayer and Monsanto defend the safety of glyphosate products.
