More than a dozen Arkansas-based poultry companies have violated state and federal laws limiting the disposal of animal waste in the Illinois River watershed, argues Oklahoma's attorney general. Oklahoma is requesting a preliminary injunction to stop poultry companies from dropping animal waste in the 1 million-acre watershed. State Attorney General Drew Edmondson maintains that unless the court grants the request by the spring, the fecal bacteria found in the waste could pose a health threat to hundreds of people who visit the river valley each year... Patrick Ryan, an attorney for Tyson Foods, Inc., responded that the injunction seeks to disrupt an industry that has operated successfully in the watershed for decades.
