Caught in the Crosshairs: The Flawed and Flimsy Case Against a Widely Used Weed Killer

A near kin to the GMO controversies that ITIF deconstructed earlier this year in a comprehensive guide for policymakers is the drumbeat of often specious criticism directed at some of the other essential inputs for innovative, commercial-scale agriculture. The latest case in point was an announcement last week from the International Agency for Research on Cancer (IARC) that one of the world’s most widely used weed killers, this time 2,4-D, is “possibly carcinogenic.” Following on the heels of a similar, highly suspect and widely criticized claim regarding glyphosate a few months ago, one would be justified in asking the question: Does the evidence really indicate 2,4-D, widely used for seven decades, has been causing cancer in humans, and requires we change the way we handle it? In fact, no, it doesn’t. Let’s take a closer look.

The announcement from IARC comes in the form of a brief report of barely 1,000 words, of which one-third (about one page of text) is devoted to 2,4-D. The details of the evidence considered and the reasoning applied are largely relegated to the monograph that will follow, after the indefensible headlines are in the

Points To Consider: Unfounded Claims of Glyphosate Accumulation in Breast Milk

Original Sources:  Press Release: “Glyphosate Testing Full Report: Findings in American Mothers’ Breast Milk, Urine and Water,” Mom’s Across America; Article: “World’s Number 1 Herbicide Discovered in U.S. Mothers’ Breast Milk” by Zen Honeycutt and Henry Rowlands, Sustainable Pulse

Primary Claims:

  • “In the first ever testing on glyphosate herbicide in the breast milk of American women… found ‘high’ levels in 3 out of the 10 samples tested. The shocking results point to glyphosate levels building up in women’s bodies over a period of time, which has until now been refuted by both global regulatory authorities and the biotech industry.”
  • “The levels found in the breast milk testing of 76 ug/l to 166 ug/l are 760 to 1600 times higher than the European Drinking Water Directive allows for individual pesticides (Glyphosate is both a pesticide and herbicide). They are however less than the 700 ug/l maximum contaminant level (MCL) for glyphosate in the U.S., which was decided upon by the U.S. Environmental Protection Agency (EPA) based on the now seemingly false premise that glyphosate was not bio-accumulative.”
