The Scientific Evidence Justifies Banning Glyphosate

The primary scientific study pesticide regulators worldwide used to justify the approval of Glyphosate, the active ingredient in Roundup and many other herbicides, has been retracted due to fraud.

This study, by Gary Williams, Robert Kroes, and Ian Munro, was used to cast doubt on the numerous published studies showing that Glyphosate caused cancers and many other diseases.

Researchers Alexander A. Kauro and Naomi Oreskes published a study in Environmental Science and Policy that identified multiple flaws in the Williams paper, including the fact that it was ghostwritten by Monsanto employees, which constitutes academic fraud. The Williams paper used unpublished studies from Monsanto and ignored a large number of scientific studies showing the multiple diseases Glyphosate causes, including cancer.

This paper was cited and used by regulators as the basis for approving the use of glyphosate-based pesticides and overriding the evidence presented in hundreds of studies showing the immense harm caused by them to human health and the environment.

This retraction comes a few months after the landmark study on glyphosate by Panzacchi et al. was published on June 10, 2025, examining total lifetime exposure to the so-called ‘safe’ levels to which most people are subjected [2].

The study found that the lowest dose of 0.5 mg/kg, which is four times lower than the US Environmental Protection Agency’s (EPA) proposed ‘safe’ level, caused increased rates of both benign and malignant tumors in various parts of the body compared to the controls. These tumors included leukemia, skin, liver, thyroid, nervous system, ovary, mammary gland, adrenal glands, kidney, urinary bladder, bone, endocrine system, pancreas, uterus, and spleen. [2,3]

Now that William’s study has been retracted, the main reason for trusting the safety of glyphosate-based herbicides has disappeared, leaving no reason to avoid banning these highly toxic poisons that pollute nearly every part of the environment and the bodies of most living creatures, especially us and our children

There are an enormous number of published scientific studies showing that glyphosate-based pesticides are responsible for multiple serious health problems for people, animals, and the wider environment.
