( Reuters ) - South Korea has started culling over 300,000 chickens and other poultry after confirming an outbreak of highly virulent bird flu at a farm in the southwest -- its first case in 13 months, the country's farm ministry said.
The ministry said late on Thursday the strain of bird flu at the farm in Gimje, about 215 km ( 135 miles) south of Seoul, was confirmed as the deadly H5N1 strain. Workers have started slaughtering birds at the farm and six other farms within 500 meters radius of the outbreak site.
On Wednesday, the farm, which raises 150,000 birds, reported the death of around 2,400 birds since last Saturday.
The ministry also banned distribution of 3.6 million animals within a 10 km radius of the outbreak site and the destruction of eggs produced, and already distributed, in the area.
The country has had seven outbreaks of the deadly H5N1 strain of bird flu between November 2006 and March 2007 and has spent 58.2 billion won ($59.17 million) on quarantine measures.
Bird flu has killed 238 people globally since 2003, according to the World Health Organisation.
It largely remains an animal disease, but the big concern is that it could mutate into a disease that easily passes from one person to another, triggering a deadly global pandemic.
