BEIJING (AP) - Trials have been taking place in China stemming from the country's tainted milk scandal.
In one trial, a former dairy boss testified that she began investigating product quality issues in May but did not notify authorities until August.
The state Xinhua (shin-wah) News Agency says the former board chairwoman has pleaded guilty to charges of producing and selling fake or substandard products. Three other executives face similar charges after being linked to infant formula contaminated with the industrial chemical melamine.
They could be executed if convicted.
Melamine, commonly used to make plastics and fertilizer, has been blamed for the deaths of at least six children and sickening nearly 300,000 others.
Xinhua says 17 others have gone on trial over past few days. No verdicts have been announced.
