Ten illegal food-processing sites have been closed by quality authorities in the past two months in Shanghai,  with two cases being handed over to public security authorities, officials said yesterday.

The factories were making kelp, vinegar, wine and mookcakes, said the Shanghai Bureau of Quality and Technical Supervision. In the past two months, more than 720 stores, snack bars and restaurants were closed for not having a business license, and more than 9,620 kilograms of fake or low-quality food and about 24.3 tons of fake construction materials were destroyed.
