Bird Flu Outbreak Confirmed Across Missouri, Including St. Louis County
The Missouri Department of Conservation announced on Friday that an outbreak of highly pathogenic avian influenza (H5N1) has been confirmed in multiple locations throughout the state, including St. Louis County. The disease was detected after a series of dead waterfowl and raptors were reported by wildlife officials and members of the public.
Laboratory testing conducted by the state veterinary laboratory verified the presence of the virus in samples collected from the carcasses. Officials indicated that the outbreak appears to be spreading among wild bird populations, particularly in wetlands and agricultural areas where waterfowl congregate. While the disease is primarily a concern for avian species, health authorities stress that there is currently no evidence of transmission to humans.
State officials have issued guidance for hunters, farmers, and residents to avoid handling sick or dead birds and to report any unusual bird mortality to local wildlife agencies. “The priority is to contain the spread among wildlife and to protect domestic poultry operations,” a department spokesperson said. The Missouri Department of Agriculture is coordinating with federal partners to increase surveillance, implement biosecurity measures on farms, and assess the risk to the poultry industry.
Experts note that outbreaks of avian influenza in North America have become more frequent in recent years, often linked to migratory patterns and changing environmental conditions. The current situation is being monitored closely, with authorities prepared to issue additional restrictions if the virus threatens commercial poultry or poses a heightened public‑health risk. Residents are encouraged to stay informed through official channels and to follow recommended safety practices while the investigation continues.
