Tobacco farmers in Argentina filed a lawsuit (pdf) against Monsanto and Philip Morris for requiring them to use herbicides and pesticides that caused a high rate of severe birth defects among their children. The farmers charge that Philip Morris and the subsidiary companies that bought their crops required the farmers to stop growing their native tobacco grow a new kind of tobacco instead that Philip Morris uses in its cigarette formulation for the North and South American markets. The new tobacco they had to grow required more pesticides, and the farmers had to use excessive amounts of Monsanto’s glyphosate-based herbicide Roundup — but the defendant companies did not warn them about the dangers of the herbicide, or provide the farmers with safety information about the chemical or any protective gear to wear when applying it.
