First Australian Cancer Lawsuit Over Herbicide “Roundup”

By AusSMC

A Melbourne gardener has launched legal action in the first Australian case to link cancer with glyphosate, the active ingredient in the weedkiller Roundup. While glyphosate is considered “probably carcinogenic”, some experts dispute this conclusion.

“Glyphosate is considered by the International Agency for Research on Cancer [IARC] to be probably carcinogenic to humans (https://bit.ly/2NlI6oZ). Here are the relevant conclusions:

6.1 Cancer in humans

There is limited evidence in humans for the carcinogenicity of glyphosate. A positive association has been observed for non-Hodgkin lymphoma.

6.2 Cancer in experimental animals

There is sufficient evidence in experimental animals for the carcinogenicity of glyphosate.

6.3 Overall evaluation

Glyphosate is probably carcinogenic to humans (Group 2A).

6.4 Rationale

In making this overall evaluation, the Working Group noted that the mechanistic and other relevant data support the classification of glyphosate in Group 2A.

In addition to limited evidence for the carcinogenicity of glyphosate in humans and sufficient evidence for the carcinogenicity of glyphosate in experimental animals, there is strong evidence that glyphosate can operate through two key characteristics of known human carcinogens, and that these can be operative in humans. Specifically:

  • There is strong evidence that exposure to glyphosate or glyphosate-based formulations is genotoxic based on studies in humans in vitro and studies in experimental animals. One...
