The Maryland Department of Agriculture has announced a presumptive positive case of H5 avian influenza in a commercial broiler farm in Dorchester County. This marks the fourth such case on Maryland’s Eastern Shore and the seventh in the Delmarva region, which includes operations in Delaware and Virginia. Confirmation by the U.S. Department of Agriculture’s National Veterinary Services Laboratory is awaited.
This recent case follows a similar discovery just six days ago in Caroline County. All affected premises are under quarantine, and birds have been or are being depopulated to curb disease spread. Officials assure the public that no birds from infected flocks will enter the food system.
Avian influenza is a highly contagious respiratory virus affecting poultry, including chickens, ducks, and turkeys, as well as some wild bird species. The disease spreads through secretions, manure, and contaminated surfaces. Wild birds, equipment, and even caretakers’ clothing can act as transmission vectors. Despite its severity among birds, Maryland health officials maintain that the risk to the public is low.
The state encourages poultry farmers and backyard flock owners to enhance biosecurity measures. Recommendations include cleaning and disinfecting equipment, minimizing visitor access, and monitoring flocks for signs of illness. Protective clothing and footbaths are advised for those in direct contact with birds. Additionally, spilled feed and unclean environments should be avoided to prevent attracting wild birds and rodents.
Farmers and citizens are urged to report sick birds promptly. For commercial or backyard flocks, contact the Maryland Department of Agriculture at 410-841-5810. Wild bird illnesses can be reported to the Department of Natural Resources Wildlife Services hotline.
