Food scandals and boycott
Ting Hsin Oil and Fat in late 2013 was found to have purchased tainted food products from Chang Chi Foodstuff since 2007.
In November 2013, Wei Ying-chung (魏應充), former chairman of three subsidiaries of Ting Hsin International Group, was indicted on charges of fraud as part of an investigation into the 2013 Taiwan food scandal. Wei Ying-chung is the third of four Wei brothers controlling the Ting Hsin group.[25][26]
On September 4, 2014, the Taipei City Department of Health held a press conference in the evening to explain that 12 processed products, including meat sauce and meat floss, produced by the Ting Hsin Group's Wei Chuan Company, were made using "Chun Tung Fragrant Lard" from the Chang Guann Company involved in the 2014 Taiwanese Adulterated Oil Scandal. Wei Chuan proactively reported, sealed, and voluntarily removed the products from shelves as a preventive measure. The Department of Health urged food industry operators who may have used or sold processed products made with Chun Tung Fragrant Lard to immediately stop manufacturing, processing, and selling, as well as to recall and report to the department for inventory and tracking.[27]
After the revelations, the Taiwan public boycotted Ting Hsin items, with a number of local governments, restaurants, traditional markets and schools refusing to consume the conglomerate's products.[28] On 16 October 2014, Ting Hsin announced that it will leave Taiwan's oil market and donate NT$3 billion toward food safety under the supervision of Juantai Financial Group (潤泰集團) Chairman Yin Yen-liang (尹衍樑).[29]
In November 2014, Ting Hsin's products were tested for Agent Orange since an unnamed source told authorities that the oil Ting Hsin imported from Vietnam may contain traces of the herbicidal weapon.[30]
In November 2015, six former managers of Ting Hsin International Group, including former executive Wei Ying-chung, were found not guilty of breaching the Act Governing Food Safety and Sanitation by selling substandard lard-based cooking oil. The verdict attracted immediate criticism from both the public and politicians.[31][32] Wei began serving a two-year prison term for another fraud charge in July 2017.[33] In 2018, the Taiwan High Court in Taichung overturned the 2015 verdict and sentenced Wei to 15 years in jail.[34]
