Pingtung officials started their probe after receiving a complaint that water in a local ditch had turned blood red. Photos attached the complaint showed that the ditch was like a "red river," the officials said. The factory, located near a ditch that is connected to the Touqian Creek in the southern city, had disguised itself as a food plant processing pigs' intestines, officials from Pingtung's Environmental Protection Bureau said. Further inspection on the outside of the factory discovered more red water stains. The investigators then entered a storeroom of the factory and found six barrels of pigs' intestines submerged in a red solution.
