A Taipei city government health official said Monday that no locally produced foodstuffs or cosmetics have passed the Nanoproduct testing and that the NanoMark Certification labeling on many foodstuffs and cosmetics are not genuine. Chiu Yiu-ling of the city government's Department of Health was replying to several city council members during an interpellation session who suggested that some shops have been found selling cosmetic products such as facial masks and soaps, as well as coffee and nutritional supplements, bearing NanoMark certificates on their packaging, for much higher prices. According to council member Huang Shan Shan, only 15 categories of items produced by 20 local enterprises have been given the NanoMark certification issued by the Ministry of Economic Affairs, and the some 400 items that have genuine NanoMark certificates are household electrical appliances, textile products, and other industrial products. The quality of the cosmetics and foodstuffs with Nanoproduct labels are questionable, according to the city councilwoman. Chiu pointed out that it is illegal to sell products with false labeling and said the city government will conduct an investigation into the matter.
