Tank operator Chen Chin-bao declined to open the tank for investigators and was taken away for further questioning. She is suspected to have dealings with pork originating sick animals and carcases sourced from Yunlin County.

Officials with the Department of Health under the city government said that they intend to fine Chen and continue to find the location and source of the pork.

Meanwhile, officials with the Markets Administration Office said that if Chen's illegal practice is confirmed, then her stand in the Hsining Market will be removed. The family has operated a pork stand in the Hsining Market since 1985.

When investigators and city government officials reached the freezing tanks, they found "frozen pork" labels on the tanks, but the labels did not bear the name, or cocntact details of the suppliers.

Chiang Yu-mei, a division chief at the municipal health department, said her department will further investigate the flow of pork products sold by the couple, adding that they will be subject to a fine of NT$40,000 to NT$200,000 if they are found to have knowingly sold illegal pork products. In addition, the pork products will be confiscated.

Wang San-chung, a deputy director of the Markets Administration Office said that his office would immediately scrap the contract with Chen Chin-bao if she is found guilty of illegal practice.
