BioSec Bob here on Friday, September 4, 2026 — let’s get right into it.
Researchers are testing far-ultraviolet light as a preventive tool against bird flu in poultry operations, according to Phys.org. The technology uses a specific wavelength of UV light — far-UV, which is different from the UV exposure producers might be familiar with — to inactivate viruses in controlled environments. The work is still in the research phase, but the concept centers on using this light spectrum in ventilation systems and high-traffic areas where the virus might spread between birds or contaminate surfaces. It’s one of several non-pharmaceutical approaches being explored as producers continue to deal with avian influenza pressure.
Speaking of bird flu, WATTPoultry.com is reporting that avian influenza has reappeared in a Minnesota turkey flock. This marks a fresh detection after a period without confirmed cases in commercial turkey operations in the state. Minnesota’s turkey industry is substantial — the state ranks near the top nationally for turkey production — so any detection gets immediate attention from state and federal veterinarians. The affected operation is under quarantine while testing and epidemiological work continue.
Over on the swine side, Pork Business has an update on PRRS right now. The virus continues circulating across multiple regions with varying strain pressures, and producers are reporting mixed results with vaccination and management protocols. Field reports suggest that some operations are seeing better stability with updated vaccine strains, while others are battling persistent virulent challenges. The variability underscores why herd-specific diagnostic work remains critical as we head into fall and winter months when respiratory diseases typically intensify.
National Hog Farmer is covering research into vitamin D3 supplementation for sow health and livability. Studies indicate that increasing vitamin D3 levels above standard minimum requirements correlates with improvements in sow immune function, bone density, and overall herd longevity. The research suggests dosage adjustments during different production stages — particularly during lactation and the transition period — can support reproductive performance and reduce culling rates.
Turning to the international front, foodagribusiness.world reports that African swine fever has reportedly resurfaced in Belarus, though authorities there are denying claims of a new outbreak. The situation remains unclear from a verification standpoint, but any ASF signal in Eastern Europe warrants close monitoring given the disease’s proximity to EU borders and its historical pattern of spread through the region. U.S. producers don’t face direct ASF risk domestically, but international trade and surveillance updates matter for market intelligence.
Finally, 3tres3.com is reporting on how artificial intelligence is reshaping livestock genetics selection. Breeding programs are incorporating AI tools to analyze genetic markers, health records, and performance data at scale — allowing for faster identification of animals with desirable traits for feed efficiency, disease resistance, and structural soundness. Operations using these systems report more predictable offspring performance and reduced need for culling due to genetic defects.
Keep a close eye on those Minnesota developments — bird flu and PRRS don’t take weekends off.
