OSCEOLA, Iowa — Officials are investigating a grease spill in southern Iowa that's been linked to a fish kill.
The state Department of Natural Resources says Osceola Foods, a food processor in Clarke County, reported Sunday morning that a pumping station failed. As a result, grease-water mix spilled into a ditch that leads to White Breast Creek, south of Osceola. Officials believe the mixture may reach the creek.
DNR says the mixture left small dead fish along a 1,500-foot stretch of the ditch. Straw bales were used to block the ditch as part of a cleanup effort.
Test results show various levels of dissolved oxygen levels in the tributary system. The agency says it will continue to monitor cleanup efforts.
