A
The authorities (当局) Wednesday set standards for melamine (三聚氰胺) levels in milk and related food products to ease fears following a contaminated milk powder incident．
The limits were set at 1 mg per kg for infant formula (婴儿配方奶粉)，and 2.5 mg per kg for other dairy products including liquid milk，according to a．joint statement issued by five government agencies
including the Ministry of Health．
Melamine can lead to some problems like kidney (肾) stones．The chemical has been blamed for the deaths of at least four babies，and more than 54，000 children have fallen ill after being fed such kind of milk formula．
Wang Xuening，an official with the health ministry，told a press conference。Wednesday that it is almost impossible to keep the melamine level at zero as small amounts of the chemical can leak from packaging into milk and other food products．But he warned that“purposely adding is clearly forbidden”．
“Those who add melamine to food products will bear the legal responsibility，”he said．
Chen Junshi，a researcher at Chinese Center for Disease Control and Prevention，said，“The limits will help inspectors．judge whether melamine was purposely added．”
“If the amount is more than 1 mg per kg，WC have reason to believe it was intentionally added．”
Some dairy suppliers have been found to add melamine to milk to make it appear protein-rich in tests．
Health authorities said the new limits are in line with international standards，and recognized by the World Health Organization and the UN Food and Agriculture Organization．
The US Food and Drug Administration (FDA) said last week that 2.5 mg of melamine per kg would not cause health problems but added that any infant formula sold to the US must be free of melamine．
Standards in Hong Kong and New Zealand also set a safe melamine limit in food products of 2.5 mg per kg，though Hong Kong has lowered the level for children under 3 and pregnant or lactating (producing milk) women to 1 mg per kg．
