BEIJING, Nov. 21 (Xinhua) -- China’s State Food and Drug Administration (SFDA) has warned 13 companies about manufacturing unapproved medical devices, which have been blacklisted in a new round of spot checks. Eighty percent of the photonic cosmetic machines (similar to lasers) from five companies and about 43 percent of high frequency electric knives (which can be used in dental procedures) were found to be unqualified in a spot-check that covered 17 provinces including Liaoning, Zhejiang, Beijing, Shanghai and Guangdong.
