TAIPEI – An oil factory at Taizhou City, Zhejiang Province processed lard with some unknown waste oils that were later found to contain highly poisonous pesticides. From September 2005 to date, more than 1,000 tons of lard processed in this factory entered China's markets, including restaurant and hotels.
According to China Central TV's “Weekly Quality Report,” staff members from health inspection station in Taizhou City found source materials for lard processing in the factory include some raw oil, waste vegetable and animal oil, oil that has been used for frying, and waste oil retrieved from sewage.
Results from the inspection showed that the acid value in the poisonous oil is over 11 times higher than the Chinese national standard. Experts say that the rancid fat can produce peroxide and other poisonous chemicals that are harmful to human beings.
Zhejiang Province's Center for Diseases Control and Prevention also detected highly poisonous pesticides such as Hexachlorocyclohexane (HCH) and DTT in a lard sample from the factory. The concentration was between 0.027 and 0.088 mg per kilogram.
Staff members from health and public security departments of Taizhou City reported that a strong sour smell and foul odor filled the factory.
