Thailand has detected a fresh outbreak of avian influenza among free-range chickens in the norther province of Sukhothai, media reports said Monday, according to dpa.
Livestock Development Department chief Sakchai Sribponsue said lab tests had confirmed that a dead chicken from a family farm had died of an infection with H5N1, the virus subtype causing bird flu.
All 17 free-range chickens on the farm were culled and the district declared a flu-outbreak zone, said the Bangkok Post.
It was the third confirmed outbreak of bird flu detected in Thailand this year.
Thailand's chicken industry was hard-hit by the aviation influenza pandemic that affected much of Asia in 2004 and 2005.
At the peak of the epidemic in 2004, some 25 Thais were infected by the virus, 17 of whom died.
