More than 110 people suspected of selling pork products made from diseased pigs have been apprehended by police after a yearlong investigation.

In raids on nearly 30 underground workshops, police seized more than 1,000 tons of tainted pork and 48 tons of swill oil with an estimated value in excess of 100 million yuan (US$16.13 million), the Ministry of Public Security said yesterday.

Producers obtained the pigs by bribing government livestock insurance agents, several of whom are being prosecuted, the ministry said.
