MUMBAI, TOKYO • Asia's chicken farmers are confronting the region's worst bird flu outbreak in years, with the deadly virus affecting farms stretching from Japan to India, roiling some poultry prices and showing no signs of easing.

More than 20 million chickens have been destroyed in South Korea and Japan since November.

The highly pathogenic H5N8 virus last week reached India, the world's No. 6 producer, and has already been reported in 10 states.

While bird flu is common in Asia at this time of year due to migratory bird patterns, new strains of the virus have evolved to become more lethal in wild birds, making countries on flight pathways particularly vulnerable, say experts.

"This is one of the worst outbreaks ever in India," said Indian animal health expert and former adviser to the United Nations' Food and Agriculture Organisation Mohinder Oberoi.

"There's a lot of disease in crows and ducks. People are scared of the disease in crows. They know they fly far and think they'll infect their poultry or even people."

The Asian outbreak comes as Europe suffers its worst bird flu outbreak in years, and follows on the heels of Covid-19, which hurt poultry sales early on in some places amid false disease concerns but is now driving up demand due to more home cooking.

Chicken prices in India fell almost a third last week as wary consumers, increasingly nervous about disease since the pandemic, steered clear of the meat.

Bird flu cannot infect people through poultry consumption, and the H5N8 virus is not known to have infected humans, but consumers are still fearful, said Mr Uddhav Ahire, chairman of Anand Agro Group, a poultry company based in Nashik, Maharashtra.

Live chicken prices are already as low as 58 Indian rupees (S$1) a kilogram, below the cost of production, he said.
