State environmental officials are investigating the second major fish kill this year near a meat rendering plant on the Skippack Creek.
Thousands of dead fish - mostly minnows - were found Wednesday in a one-mile stretch of the Skippack Creek in Franconia Township. That stretch is located downstream from the Moyer Packing Co. in Souderton, which was responsible for a similar fish kill in August.
The fish kill during the summer was caused by a malfunction at the Moyer wastewater treatment plant.
The Department of Environmental Protection says a representative of Moyer Packing Co. didn't think the latest fish kill was caused by a discharge from the plant. But DEP spokeswoman Lynda Rebarchak said the dead fish were found downstream from where the company discharges treated waste into the creek.
