A business in China suspected of selling counterfeit brand-name petfood online is now being investigated by a quality-control group in Shanghai, China.

The Shanghai Municipal Bureau of Quality and Technical Supervision began its investigation in February after receiving a report that a store on taobao.com was selling counterfeit brand-name cat and dog food for two years, with monthly sales of nearly 10,000 yuan (US$1,612).

The bureau and police spent a month investigating where the online store was storing the petfood products, finding that it changed warehouse sites frequently. Investigators found repacking machines, a scale, about 380 packages of petfood and empty packaging at a nearly 50-square-meter warehouse in rural Qingpu district.

According to the bureau, the owner said he hired employees to purchase ordinary petfood online and then repackage it in fake packaging that looks like the Royal Canin and Pedigree petfood brands. Police are still investigating the case.
