The 2014 Taiwan food scandal refers to a series of food safety incidents in Taiwan that came to light in 2014. Adulteration of cooking oil with recycled waste oil and animal feed oil was discovered in September 2014. Despite coming to light only in 2014, mass food adulteration by Taiwanese food conglomerates, however, has been suppressed for decades, and the food safety crisis has been among the reasons for the electoral defeat of the Kuomintang in late 2014. At least 1,256 businesses were affected in the gutter oil scandal. In November 2014 it was found that dried tofu products (a.k.a. dougan 豆乾) have been adulterated with an industrial dye, methyl yellow (a.k.a. dimethyl), for some 20 years. In December 2014, it was furthermore found that even regular non-dyed tofu has been found contaminated with carcinogens, resulting in over 25,000 kg recalled.

First case
The series of incidents first came to light on 4 September 2014, when it was discovered that tainted cooking oil was being produced by Kaohsiung-based company Chang Guann Co. (強冠企業) and branded as Chuan Tung Fragrant Lard Oil (全統香豬油). The company was found to have blended cooking oil with recycled oil, grease and leather cleaner. The recycled oil was processed by an unlicensed factory in Pingtung County owned by Kuo Lieh-cheng (郭烈成), who allegedly purchased the oil from waste recycler Hu Hsin-te (胡信德), whose factory is named Shun Te Enterprises (順德企業行), located in the Daliao District of Kaohsiung.
Chang Guann purchased up to 243 tonnes of recycled waste oil disguised as lard from the Pingtung factory, starting in February 2014. The company then allegedly refined the waste oil before mixing it with processed lard and selling the tainted product to its distributors. The recycled waste oil was collected from restaurants, and included discarded animal parts, fat and skin.
The President of Chang Guann Co. apologized to the public on 4 September 2014. He emphasized that his company was not aware and did not intentionally buy the tainted oil, and that the oil the company purchased from the illegal Pingtung factory was not cheaper than oil from other oil suppliers.
On 11 September, reports revealed that in 2014, Chang Guann had also imported 87.72 tonnes of lard oil falsely listed for human consumption from Hong Kong-based Globalway Corp Ltd. (金寶運貿易) that were actually meant for animal use only. Since 2008, Chang Guann had imported 56 batches of lard oil weighing 2,385.1 tonnes from Hong Kong, about 300 tonnes of which were purchased from Globalway Corp between 2011 and 2014.
The Taiwan Food Good Manufacturing Practice Development Association (TFGMPDA) reported that the cooking oil produced by Chang Guann has never been awarded GMP certification, although the TFGMPDA issued an apology saying that five food companies whose products have won GMP certification have used the tainted oil.
Schools around Taiwan pulled all of the products containing the tainted oil from their school meals after 16 schools were discovered to be using the adulterated oil products.
Chang Guann was found in violation of the Act Governing Food Safety and Sanitation and fined NT$50 million. Yeh Wen-hsiang (葉文祥), chairman of Chang Guann, was arrested for fraud for his role in the scandal.
The FDA began indefinitely halting imports of edible lard oil from Hong Kong on 11 September.
On 1 October, prosecutors revealed that after viewing lab results, Kuo Lieh-cheng admitted that oil he sold to Chang Guann Co. was mixed with corpse oil, gutter oil, grease and leather cleaner, and recycled oil.
On 3 October the Minister of Health and Welfare Chiu Wen-ta resigned in the aftermath of the scandal.
Second case
On 9 October, prosecutors launched an investigation into a unit of Ting Hsin International Group (頂新國際集團) over sale of alleged tainted cooking oil. Prosecutor Tsai Li-yi said Ting Hsin unit Cheng-I Food Co. (正義股份有限公司) is being investigated over allegedly mixing animal feed oil with cooking oil and then selling it for human consumption. Cheng-I Food Co. has an estimated 80 percent share of the lard and lard-based oil market in Taiwan. Wei Ying-chung (魏應充), former chairman of three subsidiaries within Ting Hsin International Group and third of the four Wei brothers controlling the conglomerate, was previously indicted on charges of fraud as part of an investigation into the 2013 Taiwan food scandal.
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. On 16 October, Ting Hsin announced that it will leave Taiwan's oil market and donate NT$3 billion toward food safety under the supervision of Ruentex Financial Group (潤泰集團) Chairman Samuel Yin.
On 17 October, the Changhua District Court granted a request to detain Wei Ying-chung. On October 21, prosecutors said according to Ting Shin's Vietnamese oil supplier Dai Hanh Phuc, the majority of animal feed-grade oil imported by Ting Shin may be used in the China market. In response, consumers in China called for a united boycott against Ting Hsin products.
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.
The Kaohsiung District Court ruled that Cheng-I Food owed NT$9.36 million in damages.
Third case
On 3 November, prosecutors in Tainan took Lu Ching-hsieh, owner of Beei Hae Edible Co. and Hsieh Ching Corp. and his wife, Lu Huang Li-hua, into custody on suspicion of manufacturing cooking oil using substandard oil. Prosecutors said Hsieh Ching had bought animal feed-grade beef tallow and vegetable oil from Jin Hong, a trading company, and then allegedly mixed the ingredients together for sale as cooking oil.
Industrial dye scandal
Tofu and seasoning products from Taiwanese manufacturers have been found adulterated in the latest of a string of related scandals beginning in November 2014. The scandal was initially uncovered by Hong Kong authorities regarding the many flavored types of dried preserved tofu, that were recalled for toxic industrial dye methyl yellow contamination, after investigation it was confirmed that this adulteration had been going on undetected for over 20 years. A major supplier to 44 manufacturers, Chien Hsin Enterprises (芊鑫實業社) of Tainan city was implicated as the origin. Despite that methyl yellow can often be detected by color (bright yellow), a further scandal erupted in the following days regarding regular tofu (white or oil color if fried). Regular tofu products were also found to be contaminated with a carcinogen. At least 25,760 kg of deliberately contaminated emulsifier for tofu have been traced to the distributor. In the following days, ramen noodle seasoning packets were also found to be contaminated with methyl yellow, include some popular major ramen manufacturers previously implicated in the prior gutter oil scandals These products are exported worldwide, including USA, Singapore, Malaysia, Indonesia, Canada, Australia, Vietnam, Hong Kong, and China, in Western countries primarily on shelves of Asian food stores. As of Dec 18, these 73 products (in chinese) have been recalled related to methyl yellow contamination.
Affected companies
According to Taiwan's Food and Drug Administration (FDA), a number of companies made food products using the tainted oil, including well-known brands such as Taiwan Sugar Corporation, Ve Wong Corp. (味王), Chi Mei Frozen Food Co. (奇美食品), Sheng Hsiang Jen Foods Co. (盛香珍食品), Gourmet Master Co. (美食達人), Yilin Group (憶霖), Hawdii Foods Co. (好帝一食品有限公司), etc. Restaurant chains, shops and stores were also affected, such as Good Morning (早安美芝城), Wu Wha Ma Dumpling Home (五花馬), Magie du Levain (樂金食品), Yu Jen Jai (玉珍齋), Lee Hou Cake Store (李鵠餅店), Black Bridge Foods (黑橋牌食品), Li Ji Cake Store (犁記餅店), etc.
Wei-Chuan Food Corporation (味全), a subsidiary of Ting Hsin International Group which was previously cited with using adulterated cooking oil in 2013, was also involved in using tainted cooking oil produced by Chang Guann. Its share price plummeted after the company announced a recall of 12 products made from the recycled oil: canned pork, pork sauces, meat paste and pork floss. The company promised refunds to its customers. The recall announcement subsequently also brought down the share prices of other related food companies.
