A potentially cancer-causing dye, aromatic amine, was found in one batch of clothing sold to youths at 21 elementary and junior high schools, Xinhua News Agency reported Monday.
The Shanghai Ouxia garment company produced the clothing in July, the Shanghai Municipal Bureau of Quality and Technical Supervision said.
Ouxia, which produces about 15,000 school uniforms annually, is one of several firms that have made uniforms for Shanghai students for the past five years, officials said.
The standards agency said the toxin was detected during a recent quality-inspection campaign.
