Re: Highly pathogenic avian influenza, India (OIE, September 8 2011): 1 New H5N1 Poultry Outbreak in Assam

Dhubri, Sept. 10: Nearly 200 birds were culled in Agomoni, Pokalagi, Jhapsabari, Kherbari, Supaikuti and Bhamundanga under Golokganj police station of Dhubri district today.

Alarm bells rang when one of 300 specimens of dead birds, sent to Bhopal for a test, confirmed two days back that they had bird flu.

Immediately, the Dhubri district administration promulgated a ban on the sale of birds in the market and an awareness campaign was launched in the affected areas.

An official source in Dhubri veterinary department said sale of birds was banned in the periphery of 3km area from the affected villages.

When contacted, Dhubri deputy commissioner Sunil Dutta said culling of birds had been started in the affected villages and a total ban was imposed on the sale of birds in the area.

Officials in the veterinary department said it sounded an alert and sent a collection of bird samples for examination to the Bhopal-based High Security Animal Disease Laboratory after bird flu spread in the Agomoni area in which nearly 300 birds died last week. Officials of the veterinary department said they had a target of culling 30,000 birds in 14 villages.

In 2008, the outbreak of bird flu in neighbouring West Bengal had begun showing side-effects in Assam and subsequently import of poultry and eggs from Bengal had been banned and nearly 50,000 birds were culled in Dhubri and Kokrajhar district in five days.

Prior to this, in 2005, the first bird flu cases were reported from some parts of Dhubri district but at that time no culling was carried out, an official source said.

In 2007, Barpeta, Nalbari, Kamrup and Kamrup (metro) districts were affected by bird flu and more than one lakh birds were culled. The ban on sales continued for a month then, an official source said.

Commissioner and secretary of health department Pratik Hajela told The Telegraph that apart from Dhubri, there has been no report of bird flu cases from other districts. He said a team from Delhi has arrived in the state to monitor the situation.

Bird culling in state after flu alert
TNN | Sep 14, 2011, 11.08PM IST

GUWAHATI: The animal husbandry and veterinary department in Assam has ordered culling of wild and domestic birds to stop the spread of avian flu in Dhubri district.

Personnel from the rapid response team culled more than 4,000 birds at Bhamundanga, which is regarded as the epicenter of avian flu in Dhubri district. "About 24,000 birds will be culled in the affected zone. Till now, we have culled about 4,500 birds," said a senior department official. "We have asked officials in Dhubri to meet the target as soon as possible. Since the disease is contagious, we don't want to take any risk," he added.

Teams from Bongaigaon and Guwahati reached 14 villages under the jurisdiction of the Agomoni revenue circle to speed up bird culling. At the moment, 25 rapid response teams are working in the area. Sources said authorities in West Bengal have sounded out an alert in Coach Behar district, bordering Assam."

Culling operation continued despite complaints from farmers and poultry keepers about inadequate compensations.
