Bird Flu Confirmed at Iowa Farm, 5.3 Million Chickens To Be KilledIowa has discovered a second outbreak of avian influenza, this time at a commercial chicken laying facility in Osceola County in northwest Iowa, the U.S. Department of Agriculture said Monday. The facility has 5.3 million hens. All the birds in the flock will be euthanized to prevent the spread of the disease, officials said. Last week, H5N2 avian influenza was discovered in a flock of 27,000 turkeys in Buena Vista County. Those birds also were euthanized. The disease is capable of killing an entire flock within 48 hours. Scientists and government officials believe the virus is being spread through migratory birds in the Mississippi flyway, where the strain previously has been identified. The birds are believed to transmit the illness through their droppings. The poultry industry has increased biosecurity efforts. Last week, officials said they were concerned the poultry-killing disease would make its way into the state’s commercial egg-laying industry, which is the largest in the nation. FULL REPORT
