Worried parents have been taking their children for medical tests
The Chinese tainted milk scandal is now under control, according to China's chief food inspection official.
Mr Xiang Yuzhang gave his reassurance on the sidelines of a food safety conference held here in Beijing.
He said that the Chinese government had taken a series of strong measures to get to the bottom of the matter and that there were now no more problems.
More than 50,000 children were treated after they were fed on baby milk powder contaminated with melamine.
"As far as I know, there will be no more bad news," Mr Xiang said.
The government says that it has sent more than 1,600 teams across the country to inspect dairy production plants.
The authorities have also detained several dozen people suspected of involvement in the supply of tainted milk.
Speaking in New York, China's premier Wen Jiabao insisted that his government would take measures to improve product quality and food safety in China in a fundamental way.
