Tianjin-based Tingyi Holdings is rebuffing reports its instant noodles sold on the mainland have been affected by a cooking oil scandal.

The company is warning it plans to take legal action against anyone who spreads this information.

In an online video, a tour guide from Taiwan is seen telling tourists from the mainland to boycott all products from Tingyi, saying the company was involved in the latest food safety incident in Taiwan.

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

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

The company has filed a formal complaint with police.
