China has put to death two of the key players in a milk poisoning scandal that led to the deaths of six infants in 2007. Zhang Yujin and Geng Jinping were executed after being found responsible for making more than 300,000 babies ill after milk powder was found to have been contaminated with the industrial chemical melamine. “Zhang Yujun was convicted of endangering public safety by dangerous means, for selling more than 770 tonnes of the tainted milk powder from July 2007 to August 2008, the official Xinhua news agency said. Geng Jinping, who managed a milk production centre, was convicted of supplying milk containing melamine to the now-bankrupt Sanlu Group and other dairies.” Nineteen others have been sentenced to prison terms for their role in the affair.
