A French court has declared the US biotech giant Monsanto guilty of chemical poisoning of a French farmer, a judgment that could lend weight to other health claims against pesticides. In the first such case heard in court in France, the grain grower Paul Francois, 47, said he suffered neurological problems including memory loss, headaches and stammering after inhaling Monsanto's Lasso weedkiller in 2004. He blames Monsanto for not providing adequate warnings on the product label. It is a historic decision in so far as it is the first time that a [pesticide] maker is found guilty of such a poisoning," Francois Lafforgue, Francois's lawyer, told Reuters. Francois and other farmers suffering from illness set up an association last year to make a case that their health problems should be linked to their use of crop protection products. The agricultural branch of the French social security system says that since 1996, it has gathered farmers' reports of sickness potentially related to pesticides, with about 200 alerts a year. The Francois case goes back to a period of intensive use of crop-protection chemicals in the European Union. The EU and its member countries have since banned a large number of substances considered dangerous.
