Avian influenza has been confirmed on two farms in Pingtung County’s Wanluan Township (萬巒) and all 220,000 birds on the two farms will be killed today, the Council of Agriculture said yesterday.

An organic farm raising about 80,000 chickens for meat was hit by the highly pathogenic H5N8 bird flu strain, while samples from an egg farm tested positive for the H5 subtype, the council said.

Both farms are run by Dawushan Livestock Products Co, the same operator that reported the first case of H5N2 in Pingtung this year on Jan. 9.

In addition, the results of tests on the carcasses of three light-vented bulbuls (Pycnonotus sinensis) found near a slaughterhouse in Miaoli County’s Jhunan Township (竹南) last week showed the trio had the H5N3 strain — the fourth and most recently detected virus strain to be found in Taiwan during the current bird flu outbreak.

The Pingtung case was the second to be confirmed among chickens, after the newly discovered H5N2 strain was found on a broiler farm in Changhua County’s Shengang Township (伸港) on Sunday, while the bulbuls were the first birds known to be affected by the new bird flu strain.

The council yesterday ordered all slaughterhouses, poultry markets and farms nationwide to cease operations until Thursday so they could be thoroughly disinfected — including all vehicles and cages.

Meanwhile, Environment and Animal Society of Taiwan (EAST) chief executive Wu Hung (朱增宏) said the council’s response was too slow, and that it should have suspended operations at such facilities after the first outbreak was reported almost three years ago on a layer chicken farm on Pingtung’s Dawushan (大武山).

A survey conducted by EAST found local authorities lack a standard culling method, Wu said, with some using chloral hydrate as an anesthetic before killing the fowl, while others kill the birds by freezing them with dry ice or suffocate them by stuffing them into bags.

The US of Department of Agriculture has banned the use of chloral hydrate during culls because it is a weak anesthetic, while freezing the animals with dry ice causes a painful death, Wu said.

Council of Agriculture Minister Chen Bao-ji (陳保基) said the council would reassess the culling methods used by local agencies and adjust them if necessary.

Despite the increasing number of bird flu outbreaks among chickens, Animal Husbandry Department division head Chiang Wen-chuan (江文全) said the impact on the nation’s poultry flocks has been limited, with about 410,000 chickens affected, or about 0.5 percent of the nation’s annual supply.

He said that geese have borne the brunt of the outbreaks, with about 416,000, or 30 percent of the nation’s total, culled as of yesterday morning.

The council’s latest statistics show that of the 274 facilities sampled so far, 239 tested positive for avian flu strains and culls have been conducted at 130, putting the total number of poultry affected by the outbreaks at about 528,000.

In related news, Yunlin County Agriculture Department Director-General Chang Shih-chung (張世忠) told a news conference in Taipei that his agency is desperately short of workers, as it receives more than 20 reports of possible infections per day and about 60 percent of the total number of geese in the region are on the council’s watch list.

The avian flu outbreak has swamped the three rendering sites in the county, which reached their capacity several days ago, Shih said.
