BOISE, Idaho (AP) — Farmers in Idaho have filed a potentially class action lawsuit against seed giant Monsanto after genetically engineered wheat was found in an eastern Oregon field.

The farmers, represented by a Boise law firm, filed the federal lawsuit Friday contending that Monsanto's development of Roundup Ready wheat resulted in increased production costs and lowered prices because the genetically engineered wheat is likely to infiltrate the non-genetically engineered wheat supply.

No genetically engineered wheat has been approved for U.S. farming, and the discovery of the Roundup Ready wheat growing in Oregon in May prompted Japan to suspend some imports of wheat. Monsanto didn't immediately respond to a request for comment, but the company has said similar lawsuits filed in other states were premature and that it will present a vigorous defense.
