China has ordered the recall of six types of tainted instant noodle products made by South Korean food company Nongshim, and strengthened inspection and quarantine procedures for instant noodle products imported from South Korea.

The General Administration of Quality Supervision, Inspection and Quarantine made the announcement on its website Friday, noting that products that fail to meet China's quality standards would not be allowed to enter the country.

South Korean health authorities announced Thursday a recall of six types of instant noodle products from Nongshim, after benzopyrene, a cancer-causing substance, was found in the company's South Korea-produced products, according to the Yonhap News Agency.

Nongshim's Shanghai branch said in a statement Friday that the blacklisted products were produced in South Korea, and China-based products were not among the blacklist, the Xinmin Evening News reported. Nongshim has three independent factories in Shanghai, Shenyang of Liaoning Province and Qingdao of Shandong Province.

Products from domestic factories were sent to a third-party testing agency to detect traces of benzopyrene, and results from the tests will be made public as soon as possible, according to the statement.

"We sell Nongshim instant noodles made in China instead of those imported from South Korea," a customer service officer, surnamed Zhao, from the Wal-Mart store on Jianguo Lu in Beijing's Chaoyang district, told the Global Times on Friday.

Taiwan's health authorities also ordered the recall of two Nongshim instant noodle products imported from South Korea in the wake of the scandal, according to Taiwan media reports.
