An outbreak of bird flu at an egg farm in Iowa is the state's first of the year, and the country's largest in more than two years. The state Department of Agriculture said Tuesday that bird flu was detected at a commercial egg-laying operation in northwest Iowa, the Des Moines Register reports. Crews are in the process of killing all 4.2 million chickens at the Sioux County farm, reports the AP. This is the biggest US outbreak since March 2022, when more than 5 million chickens were culled at another farm in Iowa, which has almost 12% of the country's layer hens, Bloomberg reports.
The US Department of Agriculture says more than 92 million chickens have been culled since the country's bird flu outbreak began in 2022. The virus is also spreading among dairy cows and at least two dairy workers have been infected. On Tuesday, the USDA said the virus had been found in alpacas for the first time, reports CNN. The agency said the infected alpacas were found on an Idaho farm where infected poultry were culled earlier this month. (More bird flu stories.)
