Health officials used dietary histories taken from the victims and genetic "fingerprinting" of the bacteria to trace the outbreak to a batch of unpasteurized apple juice that Odwalla uses as an ingredient in many of its mixed-fruit beverages.
One man in the illegal liquor business who operates in Gocharan said this batch came from a man who was "extremely greedy" and who watered down the liquor then mixed in pesticide to give it "flavour".
