A St. Louis County circuit judge has declared a mistrial in a case against Monsanto Co. and three other companies. The suit alleged Monsanto and the other companies were negligent in the production and marketing of PCBs, or polychlorinated biphenyls, chemicals it manufactured before they were outlawed in the 1970s.
Plaintiffs in the suit, who were represented by Dallas-based law firm Allen Stewart PC and The Simon Law Firm of St. Louis, said they developed blood cancer after exposure to the chemicals. The plaintiffs alleged that Monsanto continued to produce the chemicals even after it knew of their dangers.
After a jury deliberated from Tuesday to Friday without reaching a verdict, Judge Steven Goldman declared a mistrial.
