WEBSTER COUNTY, Mo. – Federal officials have confirmed the presence of highly pathogenic avian influenza in a chicken flock from southwest Missouri.

The U.S. Department of Agriculture’s National Veterinary Services Laboratory detected the HPAI in a chicken layer flock from Webster County, according to an announcement from the Missouri Department of Agriculture.

HPAI is known to be deadly in domesticated poultry. Veterinary officials with the Missouri Department of Agriculture have quarantined the affected premises, and birds on the property have been euthanized.

“Avian influenza does not present a food safety risk,” said Director of Agriculture Chris Chinn.
“Poultry and eggs are safe to eat when handled and cooked properly.”

According to the U.S. Centers for Disease Control and Prevention, the recent HPAI detections do
not present an immediate public health concern. No human cases of these avian influenza
viruses have been detected in the United States.

Missouri saw 10 positive HPAI cases earlier in 2022 in six commercial farms and four backyard
flocks, affecting nearly 435,000 birds. Nearly 9,000 hens were killed as a result of this most recent case.

Missouri poultry producers are encouraged to prevent contact between their birds and wild birds and report sick birds or an unusual increase in death losses to a local veterinarian or the state veterinarian’s office at the Missouri Department of Agriculture at 573-751-3377.
