Chinese officials confirmed bird flu was to blame for killing chickens in poultry markets in the southern Chinese city of Guangzhou, AP quoted the Hong Kong health bureau as saying Sunday. China's Ministry of Agriculture notified the administration that the birds tested positive for the H5N1 bird flu virus, marking the country's fifth outbreak among poultry this year, Hong Kong's Food and Health Bureau said in a statement. The Ministry of Agriculture also said on its Web site that last week's outbreak in Guangzhou killed 114 poultry and resulted in the slaughter of 518 more birds. But it has been contained, the ministry said.
