A bird flu outbreak sickened 2,100 geese in eastern China and killed about a quarter of them, a UN official said Tuesday, in the country's second outbreak reported in a week.
The Agriculture Ministry confirmed Monday that the birds died of the H5N1 virus near Tianchang, a city in Anhui province, said Noureddin Mona, the China representative for the United Nations' Food and Agriculture Organization.
The ministry did not say where or when the geese were infected, Mona said.
A report to the World Organization for Animal Health, posted on the group's Web site, said the outbreak was detected Oct. 20. It said 140,000 birds had been vaccinated and that quarantines and other precautions were taken.
