After operating in Beijing for over two years, Longkou brand of vermicelli noodles has been found to contain cancer-causing chemicals in Beijing and has been forced to withdraw from the Beijing market.

The Beijing Food Safety Administration has issued an announcement saying poisonous chemical sodium bisulfoxylate formaldehyde had been found in Longkou vermicelli produced by Yantai Deshengda Longkou Vermicelli Company. All the products by Deshengda have been banned from Beijing.

Sodium bisulfoxylate formaldehyde is a poisonous industrial chemical which can do great harm to health. It has been forbidden to be used as a food additive in many countries, including China. While sodium bisulfoxylate formaldehyde can improve the appearance and taste of food, research shows that it can harm the liver, kidney or even cause cancer.

Customers who bought the vermicelli can ask their dealers for a refund with the shopping bill and package of the product as proof of purchase.
