Students in 21 primary and middle schools in China's eastern Shanghai were today ordered to stop wearing their school uniforms after a cancer causing toxic dye was found in the products of a local garment firm.
The uniforms, produced by Ouxia Clothing Co Ltd in Pudong, were found to contain banned dyes which could cause cancer in a recent quality inspection campaign, the Shanghai Municipal Bureau of Quality and Technical Supervision said.
A probe is underway and the uniforms have been seized.
Six batches of the company's clothes products were substandard, the city's quality watchdog said.
The company has been one of a number of producers of school uniforms in Shanghai for five years.
Education authorities in the Pudong New Area of Shanghai said in a statement they have asked 21 schools who had purchased uniforms from Ouxia to tell students to stop wearing the clothes, which require quality examinations, state-run Xinhua news agency reported today.
