    A post-mortem later at the department´s Tai Lung Veterinary Laboratory showed the bird was an H5 suspect. Subsequent tests on the bird all indicated an H5 positive result.

    As a precautionary measure, Hong Kong´s Center for Health Protection has traced all six staff who had contact with the bird, and found they are in good health. Their medical condition will be monitored over the next few days.

    As a safety measure, all poultry farms within five kilometers of the place where the bird was found have been inspected. There have been no abnormal deaths and the chickens show no symptoms of bird flu.

    Grey herons are a frequent winter visitor, but rarely visit Hong Kong in the summer. They are not a resident species in Hong Kong.
