Australian farmer sues Monsanto over Roundup
Lawsuit filed
In 2019, New South Wales farmer Ross Wild filed a lawsuit against Monsanto, alleging that long-term exposure to Roundup caused his non-Hodgkin's lymphoma and that the product's warnings were inadequate. Bayer Australia responded that the scientific evidence supported the conclusion that Roundup did not cause the disease. The dispute became part of broader litigation over the herbicide's alleged health effects.

Company response
Denial — Bayer Australia
In a statement, Bayer Australia said it had great sympathy for any individual with cancer, but the "extensive body of science" on glyphosate-based herbicides supported the conclusion that Roundup did not cause non-Hodgkin's lymphoma.
Source excerpt
Mr Carbone said the warnings on Roundup bottles were inadequate and his client's clothes and body had been "drenched" in the herbicide over a 40-year period of use.
Mr Wild's case was lodged with the Victorian Supreme Court earlier this week.
Last year, Mr Wild was diagnosed with non-Hodgkin's lymphoma and he claims long-term exposure to Roundup's active ingredient, glyphosate, is to blame.

Roundup product-liability litigation
After Bayer acquired Monsanto, plaintiffs in the United States pursued numerous claims alleging that Roundup exposure caused non-Hodgkin lymphoma and that Monsanto failed to provide adequate warnings. Jury outcomes have been mixed, and litigation has continued through trials, appeals, and settlement discussions.
2015
Glyphosate carcinogenicity controversy
IARC classified glyphosate as probably carcinogenic to humans. Monsanto and Bayer have disputed the implications of that classification and have maintained that Roundup is safe when used according to its label. Other regulators have reached different conclusions under their own assessment frameworks.
Disputed safety and environmental marketing claims
Consumer and legal critics have challenged historical descriptions of Roundup as environmentally friendly or exceptionally safe, while the companies have defended product safety when used according to directions. The dispute concerns advertising, exposure, formulation, and the difference between hazard and risk assessments.
