A strain of highly pathogenic avian influenza, or bird flu, is spreading across wild and commercial bird flocks in the US.
This week, the USDA confirmed the presence of highly pathogenic avian influenza (HPAI) in two non-commercial backyard flocks (less than 50 birds) in Connecticut and western Iowa. While it’s possible for the virus to spread to humans, no human cases have been reported.
The detection of the bird flu in Iowa is especially concerning, considering the state is home to the largest number of egg-laying hens in the US. The 2015 outbreak of the same pathogen resulted in the death and eradication of 50 million birds across 15 states, with 33 million hens killed in Iowa alone, costing the federal government nearly $1 billion. But because the Iowa flock in question was small and non-commercial, there aren’t yet any supply chain issues in the region, says the USDA.
New confirmed cases continue to pop up across the nation. The USDA reported the most recent confirmation of the pathogen in a flock of broiler chickens in Missouri today.
This recent avian flu outbreak stretches across the country, with the first confirmed case detected in Indiana on Feb. 9. Indiana’s outbreak, which started in commercial turkeys, resulted in the killing and removal of 171,000 birds. The spread continued to Kentucky, where 284,000 birds were killed. Delaware had to destroy 1.2 million birds after an infection was detected in a commercial chicken flock.
