The General Administration of Quality Supervision, Inspection and Quarantine said it had checked 66 brands of powdered milk in 22 Chinese cities, and none of the samples was found to contain melamine, a chemical that can cause severe kidney damage.
China has introduced new food quality standards for melamine - 1 mg per kg of infant formula and 2.5 mg per kg for liquid milk, powered milk and food products containing at least 15% milk.
On September 14 Chinese dairy giant Sanlu admitted that its baby food had been contaminated with melamine. Following the announcement, a total of 53,000 children were diagnosed with kidney damage, at least four of them died. Some 5,000 children are still being treated in hospital.
The tests revealed that another 22 Chinese companies had added melamine to their milk to make it appear rich in protein. It was also found in non-dairy products, including those of global brands, produced in China.
