McDonald's restaurants in Hubei province were yesterday accused of breaching health regulations by allegedly selling used cooking oil to unauthorised agents. Health officials suspect that McDonald's outlets in Wuhan and Jingzhou are illegally selling used oil to unauthorised agents after reports that some of the oil had been found in Henan province, the official Xinhua news agency said. Their suspicions grew when an authorised agent employed by Hubei McDonald's - which had a two-year contract valid until the end of this year - failed to produce a complete record on the whereabouts of all the used oil. The situation was uncovered when officials from the Health Ministry inspected McDonald's restaurants in Beijing and Shanghai, as well as in Jiangsu, Zhejiang, Hubei and Guangdong provinces, according to Zhang Lingping, an official with the food and cosmetics supervision office under the Health Ministry in Beijing. Apart from Wuhan and Jingzhou, all other McDonald's restaurants complied with the Government's requirements, Ms Zhang said. According to a Health Ministry document, investigators found that the used cooking oil was not suitable for consumption and carried potential health risks. After the inspection, several government ministries issued a document on Wednesday giving instructions on how to process used edible oil, the dumping of which without proper processing causes pollution problems. The paper urged local governments to supervise the sale of used edible oil, Ms Zhang said. Xinhua said the McDonald's restaurants in Hubei had suspended the staff suspected of being responsible for the alleged sales. A staff member at McDonald's China public relations office in Hong Kong said the company was trying to find out about the situation but made no further comment on the Xinhua report. McDonald's in China has a policy asking all branches to sell used oil to authorised agents capable of processing it properly, Xinhua said.
