Rice mills probed over tainted products

Three rice mills in Central China's Hunan province are being investigated after rice they produced was found to be contaminated with cadmium last week, local authorities said on Tuesday.

The mills in Zhuzhou's Youxian county were ordered to recall their products and halt business operatons, the county government said.

Samples of the rice stored in the mills have been sent to the provincial quality inspection agency for examination.
