BEIJING — Chinese authorities have arrested nine people in a recent milk powder scandal, which involved the production and selling of fake baby formula under the brands of “Similac” and “Beingmate”.

China’s food safety commission under the State Council said at a press conference on April 9 that Shanghai police had transferred six of the suspects to judicial organs for prosecution and hunting down another suspect.

Shanghai police started to probe the case after receiving reports in September. From Dec 9, 2015 to Jan 7, 2016, they have arrested nine suspects and seized about 1,000 cans of milk powder, over 20,000 empty cans and 65,000 fake “Similac” trademarks.

The fake products had been sold into four provinces, including Henan, Anhui, Jiangsu and Hubei, according to Yan Zuqiang, deputy director of the Shanghai food safety office.

According to the commission, three vendors in Hubei, Jiangsu and Anhui have voluntarily destroyed 3,300 cans after becoming suspicious of the powder, while Shanghai police have confiscated another 5,000 cans. There are still 3,300 cans of fake “Similac” powder left unaccounted for, and another vendor in Anhui confessed 3,600 cans of “Beingmate” had been sold.

Authorities in provinces concerned are further tracing down the fake products.

Meanwhile, a test of 14 key items found the fake products within national safety standards, the commission added.

Deputy head of the food safety commission Teng Jiacai said the agency will further improve food safety mechanism to strengthen regulation in the industry.
