TIANJIN, Aug. 3-- Tingyi Holding Corp. on Monday denied that its instant noodles sold on the Chinese mainland were ever affected by a cooking oil scandal.

A spokesperson for the company based in north China's Tianjin Municipality said the company will take legal measures against a rumormonger who had spread the story on the internet.

In a video online, a Taiwan tour guide told tourists from the mainland to boycott all products from Tingyi as they were all involved in the latest food safety incident in Taiwan.

Last year, Ting Hsin International Group, the parent company of Tingyi, and many of Ting Hsin's suppliers were found selling cooking oil tainted with animal feed.

However, Tingyi said none of its noodles produced and sold on the mainland used ingredients supplied from Taiwan.

All Tingyi's products comply with national safety and hygiene standards, it added.

Tingyi has reported the case to the police and is awaiting an investigation.
