Hong Kong health authority announced Thursday that one of six bird carcasses found on Dec. 31, 2006, was tested positive for the avian influenza H5 virus, raising the fears of possible outbreaks in the city.

The Agriculture, Fisheries and Conservation Department has bolstered inspection and control measures against avian flu after one of six bird carcasses found on Leighton Road, Causeway Bay, tested positive for the H5 virus.

Assistant Director of Agriculture, Fisheries and Conservation Dr. Thomas Sit told reporters Thursday more tests are being conducted on the dead spotted munias collected on Dec. 31.

The testing results will be released in the coming days, he said.

Given its wild bird residing position, Hong Kong is more vulnerable to avian flu from January to March due to cross-contamination with migratory birds, according to health authority.

The department has enhanced checks on farms and pet shops, with no abnormal incidents observed so far.

Farm and shop owners have been urged to be vigilant and adopt bio-security measures, while their workers should ensure good hygiene.

Meanwhile, inspection of imported poultry and market stalls will be strengthened, the department said, and doctors will be informed of the latest situation. They must notify the Center for Health Protection of any suspected avian flu cases.

To stop people from keeping backyard poultry, Dr. Sit said a new round of village inspections will also be conducted.

He called on the public to ensure good hygiene, avoiding contact with and feeding wild birds. People should wash their hands thoroughly, he added.
