In a September 2015 French appeals case, a farmer's successful suit for damages due to health issues he blamed on Monsanto's herbicide, Lasso, and particularly, the agri-giant's failure to adequately warn users of potential harm, was upheld. Monsanto has consistently denied responsibility in the case. After the lower court ruling in the farmer's favour, Monsanto was quick to leap to an offensive position. The Reuters story on the appeal states "Monsanto reacted to the finding in June by demanding a retraction, labeling the findings by a team of international cancer scientists as "junk science." Monsanto plans on continuing court challenges to the highest French appeals court. Lasso was banned in France in 2007, some years after the product was withdrawn from the market in Canada, Belgium and the UK. In a related story, an agency of the World Health Organization (WHO), said in March that a key ingredient in "Monsanto's Roundup, one of the world's most used herbicides, was "probably carcinogenic to humans."
