New Zealand dairy giant Fonterra announced on August 2 that tests of some ingredients used in infant formula and sports drinks have turned up a type of bacteria that could cause botulism, a rare but sometimes fatal paralytic illness caused by a nerve toxin. Shanghai-based Dumex Baby Food Co., Ltd., one of the four Chinese companies involved in the scandal, has sealed up potentially tainted dairy raw materials and products and initiated preemptive recalls on August 4, according to Shanghai quality authorities.
