China’s contaminated food scandal widens
.
SHANGHAI : Chinese regulators are widening their investigation into contaminated food amid growing signs that the toxic industrial chemical melamine has leached into the nation's animal feed supplies, posing health risks to;consumers.
The announcement came after food safety tests earlier this week found that eggs produced in three different provinces in China were contaminated with melamine, which is blamed for resulting in kidney stones and renal failure in infants.
The reports are another serious blow to China's agriculture industry, which is already struggling to cope with its worst food safety scandal in decades after melamine-tainted milk supplies sickened over 50,000 children, caused at least four deaths and led to global recalls of goods produced with Chinese dairy products earlier this;fall. The tests have led to recalls of eggs and consumer;warnings. In Hong Kong, food safety officials announced this week that they would begin testing a wider variety of foods for melamine, including vegetables, flour and meat products.
The cases are fueling global concerns about Chinese food.
In the United States, worried consumers frantically e-mailed one another on Thursday and Friday about the possibility of melamine-tainted Halloween treats following a spate of news reports that some candies and chocolates made in China or with ingredients sourced in China had tested positive for high levels of melamine or been destroyed in recent weeks as a cautionary;measure. On the mainland, Shanghai and other cities are moving aggressively to test a wide variety of food products for melamine, including fish and livestock feed, according to the state-run news media, which has in recent days carried multiple reports on melamine in animal;feed.” The FDA, along with state and local authorities, have been sampling products in Asian markets since mid-September for traces of;melamine.
A spokeswoman for the Food and Drug Administration said the agency was adjusting a nationwide sampling of products for melamine “as necessary. “The FDA is currently re-evaluating its overall approach to keeping these products out of the U.
“Thus far, most of FDA's testing of milk and milk-derived ingredients and products from China focused on human foods, but have included animal feeds as well,” said the spokeswoman, Stephanie Kwisnek.;market.S.
Hong Kong food safety officials said a child would have to eat about two dozen of the eggs in a single day to become;ill.”
Asian food safety experts warned consumers not to grow too alarmed over the finding of tainted eggs because they contained much lower concentrations of melamine than the powdered baby formula that caused such widespread problems in;China. .
Still, if eggs, milk and animal feed supplies are tainted, there is the specter of an even wider array of foods that could come under scrutiny, everything from pork and chicken supplies to bread, biscuits, eggs, cakes, seafood and;candy. And last year, United States regulators put tough restrictions on the amount of melamine allowed in food;products.
Melamine was banned as an animal feed additive in China in July 2007.
“I heard some melamine dealers still sell to animal feed producers,” said Qin Huaizhen, manager at the Gaocheng Kaishun Chemical Co.
But interviews on Friday, and over the past year, with several Chinese chemical dealers who sell melamine suggests that melamine scrap, the substantially cheaper waste left over after producing melamine, continued to be added to animal and fish;feed. “In Shandong province many animal feed manufacturers buy melamine;scrap. in city of Shijiazhuang, though he insisted he has never sold melamine to animal feed producers.
Kidney experts said that there has been very little research into how the chemical disrupts kidney function.
Kidney experts said that there has been very little research into how the chemical disrupts kidney function. Dr. Fredric Coe, a professor of medicine at the University of Chicago, said that melamine is likely concentrated in the kidneys into crystals that the body cannot dissolve. Those crystals clog many of the kidney's close toly one million nephrons, which are tiny filtering units, in a process very different from the usual way kidney stones are formed, Coe said. Urination slows or ceases, and patients suffer acute kidney;failure.
Some food-safety experts are perplexed as to how melamine was allowed to seep into China's food supplies after melamine-tainted animal feed exports from China were blamed last year for sickening dogs and cats in the United States, touching off international trade and food safety disputes between the two;countries.
