H5N1 Bird Flu Spreads to Texas Dairy Herd as CDC Tracks Human and Animal Cases Worldwide

Federal and state health officials are tracking new bird flu developments this week, with the focus still on the H5N1 strain circulating in animals and a small number of humans in the United States and abroad. In the U.S., agriculture authorities in Texas confirm that highly pathogenic avian flu has recently been detected in a dairy herd, after cows showed a drop in milk production and signs of illness. According to Fox 7 Austin and state officials, the affected farm has been quarantined, and this is the first confirmed Texas dairy herd case this year. The U.S. Food and Drug Administration reiterates that pasteurization inactivates H5N1, and commercial pasteurized milk remains safe, while the CDC continues to rate the overall risk to the general public as low. CIDRAP, the Center for Infectious Disease Research and Policy, reports that in the past month highly pathogenic avian influenza has been confirmed in multiple U.S. dairy herds, including at least one in Texas and more than a dozen in Idaho, underscoring continued spread among cattle and the need for strict biosecurity on farms. On the human side, CDC-led investigations recently documented the first known cat-to-human H5N1 transmission, described in veterinary outlet dvm360, involving a person with close, unprotected contact with a sick cat. Health officials emphasize this appears to be a rare, isolated event, with no evidence of ongoing person-to-person transmission. Globally, some regions are seeing relief. RFD-TV reports that France has lowered its national bird flu alert to the lowest risk level after a steady decline in outbreaks among poultry, signaling that aggressive control measures and seasonal factors may be helping in parts of Europe. FluTrackers, a volunteer surveillance network, continues to log new poultry and wild bird outbreaks worldwide, along with sporadic mammal infections, reminding experts that H5N1 remains entrenched in bird populations and capable of jumping species. Public health agencies advise avoiding contact with sick or dead birds or mammals, using protection when working with livestock, and staying tuned to CDC and local health department updates as surveillance expands in farms, markets, and wildlife.
