Equine infectious anemia and highly pathogenic avian influenza dominated discussions at the 425th Commission Meeting of the Texas Animal Health Commission (TAHC) on September 18, 2025. The meeting revealed alarming statistics regarding equine infectious anemia, with 45 positive cases detected in horses across four states, including Texas. The commission highlighted concerns over iatrogenic transmission linked to contaminated injectable products and blood doping practices.

In a joint investigation with the State Board of Veterinary Medical Examiners and the USDA, officials are working to address these troubling findings, particularly in North Texas, where 23 positive cases have been confirmed.

The meeting also addressed the ongoing national outbreak of highly pathogenic avian influenza, which has impacted approximately 175 million birds since February 2022. In Texas, 14 premises have reported positive cases, including two commercial flocks and two backyard flocks in Brazoria and Burnett counties.

Additionally, the TAHC discussed the spillover of avian influenza into dairy and livestock, with 29 confirmed premises in Texas. The USDA's recent federal order mandates testing of unpasteurized milk for interstate movement, leading to the implementation of the National Milk Testing Strategy in Texas. So far, no positive silos have been detected in the fifth round of testing, but the commission remains vigilant, ready to coordinate responses should any positive cases arise.

The discussions underscored the critical need for ongoing monitoring and collaboration among state and federal agencies to protect animal health and mitigate the spread of these diseases.
