A federal judge has dismissed a lawsuit by Syngenta against exporters that handled shipments of corn containing the biotech trait MIR 162. A U.S. District Court Judge dismissed the counterclaims last week against ADM, Cargill and Rail Transfer. Farm Journal reports Syngenta’s claims the grain handlers were also at fault for allowing the Viptera corn, which included the biotech trait, to enter Chinese markets before approval of the trait by China. The judge said federal regulations already govern handling and inspection of U.S. grain. Meanwhile, the lawsuit by farmers against Syngenta will continue. Some farmers are seeking damages for financial losses the farmers claim they suffered when the company marketed Viptera corn before Chinese approval. The producers claim the rejection of corn exports including the trait interrupted trade and lowered commodity prices, costing them an estimated $3 billion.
