Maryland Confirms Highly Pathogenic Avian Influenza in Wicomico County

WICOMICO COUNTY, MD – Maryland state officials say a commercial poultry farm in Wicomico County has tested presumptively positive for highly pathogenic H5 avian influenza, marking the first case in the county this year and the second in the state.

The Maryland Department of Agriculture said all birds on the affected farm have been or are being depopulated, and the premises have been quarantined to prevent the virus from spreading. The birds will not enter the food supply. Final confirmation from the U.S. Department of Agriculture’s National Veterinary Services Laboratory is expected in the coming days.

Avian influenza is a highly contagious virus that spreads easily among birds through respiratory secretions and feces. Wild birds, infected poultry, contaminated equipment, and even clothing and footwear of farm workers can carry the virus between flocks.

The Maryland Department of Health said the risk to the general public is low, but farm workers and others in close contact with poultry should follow strict biosecurity measures. Authorities are urging commercial growers and backyard flock owners to monitor for signs of illness and to follow enhanced precautions.

Key recommendations include minimizing visitors, cleaning and disinfecting equipment, removing spilled feed, using protective clothing, and washing hands before and after contact with birds. Anyone who suspects an infected flock can report it to the Maryland Department of Agriculture at 410-841-5810 or email MD.Birdflu@maryland.gov. Sick wild birds should be reported to the Maryland Department of Natural Resources Wildlife Services hotline at 877-463-6497.
