BioSec Industry Briefing — Saturday, October 31, 2026

BioSec Bob here on Saturday, October 31, 2026—let’s get right into it.
A mutated strain of swine flu is spreading across the country two months ahead of what producers typically see this time of year, according to The Independent. The virus is hitting herds harder and faster than seasonal patterns would predict. Mortality rates are climbing in affected operations. Veterinarians are urging swine producers to tighten biosecurity protocols immediately and monitor animals closely for respiratory signs and fever.
Moving to a different threat on the swine side—the pork industry is watching developments with New World Screwworm closely, Brownfield Ag News is reporting. The parasitic pest has historically been eradicated from the continental United States, but renewed concern centers on potential reintroduction pathways. Industry groups are coordinating with USDA to strengthen monitoring and preparedness. Screwworm infestations can devastate herds if left unchecked.
Over on the poultry front, bird flu has confirmed its presence in Sacramento County, California. FOX40 is reporting that two backyard chicken flocks tested positive for avian influenza. Affected premises are under quarantine. State and federal officials are working the epidemiology to identify exposure sources and prevent spread to nearby operations.
South Carolina producers need to hear this one—Clemson animal health officials are urging all poultry keepers to keep domestic birds completely separated from wild waterfowl and any waters where wild birds congregate. The advisory comes as waterfowl migration season coincides with rising avian flu detections. Even brief contact or shared water sources can transmit the virus.
Back in Washington, Feed Strategy is reporting the US Swine Health Improvement Plan Act has been introduced in the House. The legislation proposes new funding mechanisms and coordinated disease surveillance infrastructure for swine operations. Industry groups are reviewing the bill’s language and funding levels for compatibility with existing herd health programs.
Finally, Hawaii’s got a fresh alert—WATTPoultry.com reports avian flu virus has been detected in wastewater samples collected across the islands. The finding suggests active circulation in poultry or wild bird populations. State agriculture officials are ramping up testing at commercial and backyard operations statewide.
Halloween weekend or not, keep those barns locked down tight.
