Watchdog urges fake-brand baby formula probe

China's top food safety regulator demanded on Monday a thorough investigation into the whereabouts of 17,000 cans of fake-brand baby formula - which have been sold nationwide - to eliminate risks.

According to the China Food and Drug Administration, quality inspections by police in Shanghai showed that the formula met national standards and posed no safety threat.

The Supreme People's Procuratorate said on its website in March that six people were arrested in Shanghai in January for producing and selling the fake-brand formula, from which they profited by nearly 2 million yuan ($310,000).
