Via The Poultry Site: Guangdong Farm Culls Chickens after Positive H7N9 Test.
Authorities in Zhuhai in Guangdong province have ordered 80,000 chickens on one farm to be slaughtered after the birds tested positive for the H7N9 avian influenza virus.
Zhuhai authorities ordered 80,000 chickens at a local farm slaughtered after tests showed that some chickens at the facility were infected with H7N9, according to official sources in China, citing a report in Macao Daily on 16 March.
The farm in the Doumen district was registered to provide live poultry to Hong Kong and Macao. Authorities from Macao and Doumen's agricultural bureau found chickens infected with the bird flu virus on the farm.
When H7N9 emerged last year, the authorities searched everywhere for H7N9 and found it only rarely. This is the first time I can recall when H7N9 has been found widespread within a poultry farm.
