The poultry companies named in the 2005 Oklahoma lawsuit over bird waste in the Illinois River watershed are challenging a settlement that would exonerate one company from the lawsuit, according to a Forbes article.


The companies filed a motion last week alleging that Oklahoma Attorney General Drew Edmondson's deal with Willow Brook Foods Inc. for the company to pay $120,000 was improperly entered into and stated they want Edmondson to explain how the $120,000 figure was determined.


"[Edmondson] needs to advise the public whether he will use the same formula or approach for other defendants," said Robert George, an attorney representing Tyson Foods Inc.



A trial is set for September.


The companies named in the lawsuit include Tyson Foods Inc., Tyson Poultry Inc., Tyson Chicken Inc., Cobb-Vantress Inc., Cal-Maine Foods Inc., Cal-Maine Farms Inc., Cargill Inc., Cargill Turkey Production LLC, George's Inc., George's Farms Inc., Peterson Farms Inc., and Simmons Foods Inc.
