New Zealand milk dumped as toxic oil and gas drilling mud taints 14 Fonterra tankers by Isobel Ewing and Laird Harper, October 31, 2013, Marlborough Express
Fourteen tankers were contaminated with the mud on Friday before the error was caught, including six which had gone on to pick up raw milk. The Taranaki Daily News understands the mud was oil and gas drilling waste. … The Clean In Place (CIP) system had to be cleaned out twice before it was deemed to be safe to use, Walls said. The milk carried by the six contaminated tankers, worth roughly $150,000, was disposed of at a wastewater treatment plant in Taranaki.
