evening, the farm was immediately quarantined, and the farmer was stopped
from selling chickens," an AFCD spokesman said.
"Most of the remaining 50 000 chickens on the farm are housed in separate
sheds from the ones in which the dead chickens were found. These chickens
show no clinical symptoms of infection. We have decided to put these
chickens under close observation. Depending on our observation, we will
take appropriate measures to control the spread of the infection."

Poultry Market on 20 Dec 2002. That batch passed blood tests at the farm

found at that time. AFCD staff inspected 43 other chicken farms yesterday

under close observation in the coming days.
"We remain on full alert and will take appropriate actions as and when

On 10 Dec 2002, Penfold Park in the centre of Sha Tin racecourse was closed
for a month after 31 ducks and geese died of the H5 virus in 2 weeks. A
week later 20 chickens were found dead at a market stall in Mui Wo.
