A strain of highly pathogenic avian influenza, or HPAI, tore through U.S. poultry farms in early 2025, leading to the culling of tens of millions of birds and a surge in egg prices. ^[1] Far-UVC light differs from conventional germicidal UV light because it can inactivate viruses and bacteria without penetrating deeply enough to damage human or animal skin and eyes. ^[2] Morgan Farnell, an avian microbiology and immunology professor at Texas A&M AgriLife Extension Service, stated that the current HPAI outbreak began around 2022 and has not ended, with the virus still being found in Texas wildlife. ^[3] Ziteng "Tim" Xu, a scientist at Texas A&M AgriLife Research, will lead the third and final phase of a multiyear study starting in February to test far-UVC light in real-world commercial poultry conditions. ^[4] The study will span two years and include four flocks, two raised under summer conditions and two under winter conditions, funded through a $2 million U.S. Department of Agriculture Animal and Plant Health Inspection Service grant. ^[5] The U.S. poultry industry suffered significant losses and soaring egg prices after a highly pathogenic avian influenza outbreak began around 2022 and continued into early 2025. ^[6]
