BEIJING - Chinese police have seized 350 suspects involved in 120 food-related criminal cases since a crackdown on food-related crimes began last month.

The police destroyed more than 220 underground food workshops during the crackdown, the Ministry of Public Security revealed Sunday.

The crackdown will last throughout 2013, according to the ministry.

Currently it is focusing on quality problems concerning cooking oil, meat and other products which are in great demand during the Chinese Lunar New Year holidays.

The ministry said it has organized inspections in supermarkets, food exhibitions, tourist sites and food companies.
