Vigilance continues as industry fights bird flu
In November 2024, Oklahoma confirmed its first case of highly pathogenic avian influenza (HPAI) in a commercial poultry flock. Since then, immediate response efforts have been set into motion by state and federal officials, according to Oklahoma State University (OSU) Extension Veterinarian Dr. Rosslyn Biggs.
When infected flocks are identified, all birds impacted by the infection are depopulated, and a control zone is established around the location to prevent further spread, Biggs said in an interview with OSU’s agricultural program SUNUP. Additional testing then commences in both commercial and privately owned flocks within the zone, with a broader surveillance area extending beyond it.
“There are also movement restrictions and quarantines in that control zone, affecting both poultry and poultry products, to ensure the virus is not inadvertently spread,” Biggs explained.
HPAI is highly contagious among birds and often results in sudden, high mortality rates. Symptoms include respiratory distress, lethargy, diarrhea, and decreased egg production. Because no readily available vaccine exists, biosecurity measures are crucial for preventing the spread of the virus.
The U.S. Department of Agriculture (USDA) is working closely with the Oklahoma Department of Agriculture and has activated emergency response plans. Testing is being conducted at the Oklahoma Animal Disease Diagnostic Laboratory and other regional facilities, including those in Arkansas.
Officials caution that the risk of avian influenza increases during seasonal migratory waterfowl movements. Hunters handling ducks and geese are urged to take precautions to avoid inadvertently introducing the virus to domestic poultry.
“If bird owners suspect any signs of avian influenza, we encourage them to report their concerns and seek assistance with additional diagnostics,” Biggs said.
Despite concerns, officials assure the public that poultry and eggs remain safe for consumption if cooked to proper temperatures. Infected birds do not enter the food supply.
OSU Extension is offering educational resources, including online biosecurity courses and fact sheets, to help poultry owners protect their flocks. More information is available at sunup.okstate.edu.
