Fourteen gangs involved in the smuggling of frozen meat products that pose huge health risks have been hunted down and the products seized in a recent crackdown, the General Administration of Customs said.

Customs officials sealed more than 100,000 metric tons of smuggled frozen meat worth up to 3 billion yuan ($483 million), including frozen chicken wings, beef and pork, the administration said.

The crackdown took place in June in 14 provinces and regions.
