Users of Teflon non-stick cookware in China have an increased risk of cancer as US chemical maker DuPont was accused of failing to report on human health risks from a key ingredient in Teflon.

This kind of cookware is very popular in the country and their content is mainly Teflon provided by DuPont, according to Monday's CRI online.

But the company thinks that the Teflon products are not harmful to human health.

Authorities in Beijing and Guangzhou cities are examining the cookware and checking their chemical content.

Any products that pose a threat to health will be removed from the shelves immediately.

The US Environmental Protection Agency is now planning to impose a 300 million dollar fine on DuPont.
