U.S. reports highly lethal bird flu at commercial chicken farm in Missouri
CHICAGO, March 4 (Reuters) - The U.S. Department of Agriculture reported an outbreak of a highly lethal type of bird flu in a commercial flock of chickens being raised for meat in Stoddard County, Missouri, on Friday.
The outbreak was confirmed as the H5N1 strain of avian flu in a flock of about 240,000 broiler chickens in the southeastern Missouri county, the USDA's Animal and Plant Health Inspection Service said.
Over the past month, highly lethal bird flu cases have been confirmed at 10 commercial chicken and turkey farms in four states, triggering export restrictions for U.S. poultry products. [nL1N2UY30W]
