Two defendants have been sentenced to die, and a top industry executive drew life imprisonment, in connection with the 2008 melamine scandal in China. The toxic chemical was added to Chinese food and beverage products to cheaply boost their protein contents.

Tian Wenhua, the former head of Sanlu – one of China’s leading dairy producers, was sentenced to life in prison for her role in allowing the sale of such products, Reuters reports. The two other defendants drew death sentences for their involvement in contaminating milk that sickened thousands of children. Another three former Sanlu execs drew prison sentences of five to 15 years.
