Glyphosate and the Casey Means Hearing

Well, I can’t say I’m surprised that pesticides and glyphosate surfaced during the Senate confirmation hearing of Casey Means. Here’s a concise summary of the exchange with Sen. Markey.

Markey opened with a broad discussion of environmental contributors to chronic disease, quickly zeroing in on glyphosate; the world’s most widely used herbicide. He emphasized its alleged links to cancer and chronic illness, clearly invoking the conclusions of the International Agency for Research on Cancer monograph program (though not by name). He referenced prior remarks suggesting glyphosate damages DNA and is “probably carcinogenic to humans.”

Means responded that the issue warrants deeper scrutiny, citing concerns about long-term, population-level toxic impacts and acknowledging the persistence of public unease.

The exchange then shifted to politics. Markey referenced a Trump-era executive order promoting pesticide use and a Supreme Court brief filed by the Solicitor General supporting Monsanto’s position in ongoing cancer litigation. He framed these developments as prioritizing corporate protection over public health and pressed Means directly: do such actions put Americans at risk, given glyphosate’s alleged carcinogenic potential?

Means answered cautiously. She acknowledged potential risks but emphasized the agricultural system’s dependence on glyphosate, arguing that any shift away from it would require a gradual transition rather than immediate bans. Markey accused her of softening earlier positions and drew comparisons to agency hesitancy under Secretary Kennedy. Means closed by promising that MAHA-led studies would explore safer alternatives, while conceding that rapid change would encounter significant industry resistance.

If you’re following how science, litigation, and politics intersect in chemical policy, it’s worth watching the exchange yourself. I suspect the framing, especially around IARC versus regulatory assessments, will matter more than the sound bites.

Also notable (for me) the presence of Vani Hari (“Food Babe”) seated with the Calley Means family, just part of the environement and how this confirmation battle is staged. I’d encourage listening, maybe more on this soon. Looking forward to reactions and how journalists will cover.
