By P.J. Huffstutter CHICAGO (Reuters) - Foster Farms and its London insurers are facing off over the definition of "product recall" as the poultry producer seeks payment of $14.2 million in claims arising from a government-mandated shutdown of one of its plants, court documents show. The company in June sued a group of Lloyd's of London [LOL.UL] underwriters, arguing the closure and resulting product losses constituted a recall under the terms of the company's insurance. Foster Farms, one of the largest U.S. chicken producers, filed an amended complaint last Thursday in U.S. district court in Fresno, California, saying three insurance underwriters at Lloyd's acted improperly when they rejected its claims associated with January production stoppages mandated by federal regulators. In essence, the insurers said the Foster Farms policy covered economic losses when the company pulled back its products from customers, not when the company destroyed products that it had not yet shipped to customers, documents in the case show.
