The Taiwanese gutter oil scandal just keeps escalating as mainland cities, including Shanghai, Xiamen and Wenzhou, discover more and more food products containing tainted lard supplied by Taiwanese oil manufacturer, Chang Guann Co.

According to the Shanghai Food and Drugs Supervision Bureau, approximately 8,700 bags of food suspected of using the substandard oil were seized in Shanghai. In Xiamen, about 4.9 tons of food was suspected of containing the contaminated oil, said officials from the City’s Entry-Exit Inspection and Quarantine Bureau, Hong Kong newspaper Wen Wei Po reported on September 14.

Of the 4.9 tons of food seized in Xiamen, 3.2 tons consisted of pork products and 1.7 tons were made up of butter biscuits. The two food manufacturers, Wei Chuan Food (味全) and Triko Foods Co Ltd (盛香珍食品), were found to be using tainted oil from Chang Guann.

Wenzhou, in eastern China, also uncovered approximately 60 kg of food allegedly containing the tainted oil, which included noodles, beef and sunflower seed oil, the China Daily reported.

Since the gutter oil scandal first exploded in Taiwan in early September (when Chang Guann was found to be mixing lard oil with gutter oil collected from food waste or slaughterhouses and selling it as cooking oil), about 250 food products involving roughly 1,200 food companies and processors were found to have used oil supplied from the company.

In Hong Kong, cakes made from the gutter oil supplied by the Taiwanese firm were sold by 7-Eleven, Starbucks, Maxim, Café Express and Arome Bakery, to name a few. A comprehensive map of the stores, shops and restaurants suspected of using the substandard oil in Hong Kong can be found here by SCMP.
