The spokesman added that further confirmatory tests are being conducted.

The dead bird was found and collected on the second floor staircase of Wing Yiu House, Lai Yiu Estate. Oriental magpie robins are common resident birds in Hong Kong.

The spokesman said cleaning and disinfection have been stepped up at the venue, adding that there are no poultry farms within 3 kilometres of the location where the dead bird was found.

In view of the case, the AFCD said it has phoned poultry farmers to remind them to strengthen precautionary and biosecurity measures against avian influenza. Letters have been issued to farmers, pet bird shop owners and licence holders of pet poultry and racing pigeons reminding them that proper precautions must be taken.

The spokesman said the department would conduct frequent inspections of poultry farms and the wholesale market to ensure that proper precautions against avian influenza have been implemented. The department will continue its wild bird monitoring and surveillance.

"People should avoid contact with wild birds and live poultry and their droppings. They should clean their hands thoroughly after coming into contact with them.

"The public can call 1823 for follow-up if they come across suspicious, sick or dead birds, including the carcasses of wild birds and poultry," the spokesman said.

The statement said that the Food and Environmental Hygiene Department (FEHD) will continue to be vigilant over imported live poultry as well as live poultry stalls. It will also remind stall operators to maintain good hygiene.

The Department of Health will keep up with its health education to remind the public to maintain strict personal and environmental hygiene to prevent avian influenza.

The AFCD, the FEHD, the Customs and Excise Department and the Police will strive to deter the illegal import of poultry and birds into Hong Kong to minimise the risk of avian influenza outbreaks caused by imported poultry and birds that have not gone through inspection and quarantine.
