People should eat more vegetables and fruits as well as drink plenty of water if they are afraid of consuming products containing swill mixed with various other oils produced and sold as lard, toxicology experts said.
Following edible oil industry crises in October last year, the industry has again been shaken after Pingtung County received tips of a factory manufacturing tainted oil, allegedly headed by Kuo Lieh-cheng (郭烈成), whose company reportedly reclaimed oil from kitchen waste as well as grease out of leather processing plants, and sold the final product to Chang Guann Co (強冠企業).
The Food and Drug Administration’s investigation into the case so far suggests that Kuo mixed his products in a 1:1:3 ratio, using one part each of recycled oil and three parts of lard per mixture.

Linkou Chang Gung Memorial Hospital department of clinical toxicology director Yen Tsung-hai (顏宗海), said that the swill was easily oxidized, and that due to the unsanitary location where it was processed, may contain large amounts of germs, aflatoxin and benzopyrene, the latter two of which are carcinogenic.
Though swill commonly refers to liquid waste, in this instance it specifically refers to recycled oil collected from various sources such as kitchen fryers, restaurants and grease traps.
Yen also said that if oils from leather fabrication were used, depending on whether the leather had been dyed, minute traces of heavy metals such as chromium or arsenic may be present, adding that such materials often damage the livers and kidneys.
Yen said that eating vegetables would help the body rid itself of aflatoxin, adding that fruits rich in vitamin C would also help expel benzopyrene.
Separately, colon and rectal surgery expert Wang Jaw-yuan (王照元) said that whether the case has direct correlation with Greater Kaohsiung’s and Greater Tainan’s surge in death rates of patients with colon and rectal cancer over the past years required further research.
Meanwhile, Consumers’ Foundation secretary-general Lei Li-fen (雷立芬) yesterday said the government had failed to ensure that manufacturers check products themselves or send them for independent inspection.
Lei said that Chang Guann Co had been honored with an award from the General Chamber of Commerce.
According to Lei, the government or business groups, while bestowing awards on manufacturers, have not been rigorous in checking if the enterprises have carried out their social responsibilities.
These, she said, are the reasons why major food companies like Wei Chuan Foods Corp (味全食品工業), one of the nation’s oldest and biggest food enterprises, have been involved in food scandals.
Lei also faulted consumers for their weak responses to the scandals, which she said allowed food enterprises to consider only their own interests and profits and ignore the need for establishing proper safety controls.

CHINA’s BULLYING: The former British prime minister said that he believes ‘Taiwan can and will’ protect its freedom and democracy, as its people are lovers of liberty Former British prime minister Boris Johnson yesterday said Western nations should have the courage to stand with and deepen their economic partnerships with Taiwan in the face of China’s intensified pressure.

Johnson, who is visiting Taiwan for the first time, said he had seen Taiwan’s coastline on a screen on his indoor bicycle, but wanted to learn more about the nation, including its artificial intelligence (AI) development, the key technology of the 21st century.
