ST. LOUIS - A Missouri appeals panel on July 23 said that the former Monsanto Co. owed a duty to people who were exposed to polychlorinated biphenyls (PCBs) and that the plaintiffs' exposure to the potentially cancer-causing chemical was foreseeable (Sanford Clair, et al. v. Monsanto Company, et al., No. ED99246, Mo. App., Eastern Dist., Div. 3; 2013 Mo. App. LEXIS 854).
