XUZHOU, CHINA — Before Mao Lijun's business exported tainted wheat products that may have killed American pets, his factory sickened people and plants around here for years. Farmers in this poor rural area about 400 miles northwest of Shanghai had complained to local government officials since 2004 that Mao's factory was spewing noxious fumes that made their eyes tear up and the poplar trees nearby shed their leaves prematurely. Yet no one stopped Mao's company from churning out bags of food powders and belching smoke — until one day last month when, in the middle of the night, bulldozers arrived and tore down the facility.
It wasn't authorities that finally acted: Mao himself razed the brick factory — days before the investigators from the U.S. Food and Drug Administration arrived in China on a mission to track down the source of the tainted pet food ingredients. In the end, Chinese authorities caught up with Mao and arrested him. And Tuesday, after weeks of denials, China acknowledged that Mao's company and another Chinese business had illegally exported wheat and rice products spiked with melamine, a chemical used in making plastics and fertilizers. That chemical is banned in foods in the U.S. China's watchdog agency said the businesses had added melamine to the food ingredients "in a bid to meet the contractual demand for the amount of protein in the products." Melamine can make animal feed appear to have more protein than it actually does.
Besides turning up in pet food, melamine has been found in feed for thousands of hogs and millions of chickens in the U.S. The FDA said Tuesday that melamine-contaminated foods also were fed to fish raised for human consumption. But in each case, U.S. officials said there was little risk to human health.
The FDA also said that although the tainted Chinese products were labeled as wheat gluten and rice protein, they were actually ordinary wheat flour — with melamine and related nitrogen-rich compounds. Melamine producers in China have said that melamine scrap, a cheaper form of the chemical, has been widely sold to entrepreneurs who use it to fool farmers into thinking that they are getting higher-nutrient animal feeds. Among the apparent buyers of melamine scrap were Mao, head of Xuzhou Anying Biologic Technology Development Co., and Binzhou Futian Biology Technology Co. in Shandong province.
