BBC has an update on the sentences handed down to those held responsible for the contaminated milk crisis:

State media said a court in Hebei Province rejected the appeal by Tian Wenhua, the former chairwoman of now-defunct Sanlu Group, at the centre of the dairy contamination.

The 66-year-old was the highest-ranking executive charged over the scandal.

According to state media, the court also upheld a death sentence against Zhang Yujun, convicted of producing and selling the tainted milk, and a life sentence against Zhang Yanzhang, who acted as a middle man in supplying the toxic product to dairies.
