More than 1,000 poultry birds infected with A/H5N1
HA NOI (VNS) ? More than 1,000 fowls in a poultry flock from Mekong Delta province of Tra Vinh, have been found to be infected with A/H5N1 avian flu, according to the Viet Nam Veterinary Department's Can Tho-based Veterinary Agency.
Among the animals that belonged to Nguyen Huu Toan, a farmer in Dua Do hamlet, Nhi Long Phu commune, Cang Long District, 1,000 chickens were 70 day old and 18 ducks were 40-day-old. As many as 892 fowls (890 chickens and 2 ducks) that tested positive for A/H5N1 flu had died.
The local authority destroyed all the dead fowls and culled the remaining 126 ones.
Nhi Long Phu commune was affected twice by avian flu outbreaks that occurred in February and March of 2014. Therefore, the risk of further outbreak in the province would be very high.
The provincial Veterinary Department has cooperated with local authorities to urgently implement measures to tackle the disease, control the local flock and those transported from other places to the locality in accordance with regulations to prevent the disease from spreading on a large scale. ?
