The ministry has also shut down 13 underground workshops, which were involved in the oil manufacture. A report from China Central Television (CCTV) indicated that the oil was made using animal fat from slaughterhouses, which included rotten meat and animal viscera.
The ministry has announced to enhance its efforts to seize the illegal oil and safeguard food safety, reported Chinadaily.com.cn.
In 2011, the Chinese authorities had seized 'gutter oil', which was made by reprocessing waste oil from restaurants. Another food scandal which surfaced during the year included the addition of cancer-causing clenbuterol to pig feed to produce lean meat.
In response, the country had launched nationwide food safety campaign in August 2011 to curb such illegal practices.
