China has executed two people for their roles in a tainted milk scandal that led to the deaths of at least six infants and sickened up to 300,000 others.

The official Xinhua news agency says Zhang Yujun was executed for endangering public safety and Geng Jinping was put to death for producing and selling toxic food.

Xinhua says that Zhang produced nearly 800 tons of a melamine-laced protein powder, of which he sold more than 600 tons, between July 2007 and August 2008.

Xinhua says Geng sold more than 900 tons of tainted milk, to the now bankrupt Sanlu Group, which used to be the country's biggest dairies.

Earlier this year, in January, 21 people were tried and sentenced over the scandal including Sanlu Group's general manager, Tian Wenhua.

Tian was given a life sentence after pleading guilty to charges of producing and selling fake or substandard products.

Tian's appeal of the life sentence was rejected in March.
