First Case of Avian Flu This Year Found in Shelby County Poultry Flock

December 14, 2025 – SHELBY COUNTY, Texas — State and federal animal health officials have confirmed a case of highly pathogenic avian influenza in a commercial poultry flock in Shelby County, marking the first detection of the virus in Texas this year.

Shelby County is about 150 miles southeast of Hopkins County.

Officials with the Texas Animal Health Commission and the U.S. Department of Agriculture say the virus was identified during routine monitoring after birds began showing symptoms consistent with avian influenza. The affected flock has been quarantined, and control measures are underway to prevent the disease from spreading to other poultry operations.

Highly pathogenic avian influenza is extremely contagious among birds and can cause severe illness or death. While the virus does not pose a significant risk to the general public, officials say it can have major economic impacts on the poultry industry if not contained quickly.

State officials emphasized that poultry products remain safe to eat when properly handled and cooked. There is no evidence of infected birds entering the food supply.

Biosecurity measures are being reinforced statewide, and poultry owners — including backyard flock operators — are being urged to limit contact between their birds and wild birds, disinfect equipment, and report any unusual illness or sudden deaths.

Texas agriculture officials say early detection and rapid response are critical to limiting the spread of avian flu. Surveillance efforts will continue across the state as migratory birds move through the region, increasing the risk of additional cases in the coming months.
