US reports highly lethal avian influenza in Arkansas chickens
The number of infected birds is unknownA highly lethal form of avian flu infected a commercial flock of breeding chickens in Arkansas, Reuters reported, citing the US Department of Agriculture (USDA on Friday, widening an outbreak of the disease in the key southern producing region.
Nationwide, more than 47 million birds have been killed by avian influenza or culled to control its spread this year in the nation's worst outbreak since a record 50 million birds were wiped out in 2015.
Top states for raising broiler chickens for meat, such as Georgia and Alabama, had largely escaped infections in commercial flocks before the case in Arkansas.
Arkansas produced more than 1 billion broiler chickens last year, making it the third biggest producing state, US government data show.
The disease hit a commercial broiler breeder chicken flock in Madison County, Arkansas, in the northwest corner of the state, the USDA said. State officials quarantined the premises, and birds there will be culled, the agency said.
Europe has experienced its worst avian influenza crisis ever this year, with nearly 50 million poultry culled. The persistence of the virus over the summer has raised the risk of widespread infections next season, the EU's Food Safety Agency said.
