Highly Pathogenic Avian Influenza was detected in a backyard flock in northern Middlesex county on November 1, 2022.

Since December 2021, HPAI has been found in wild and domestic birds across North America. This means that all domestic poultry in Massachusetts may be at risk of exposure. Good biosecurity will protect your flock and your facility against this virus.

Wild waterbirds including shorebirds and waterfowl, especially dabbling ducks like Mallards, are most likely to carry HPAI. Domestic poultry are exposed to this virus through contact with infected birds, their droppings, or feathers.

Keep your birds in covered runs and coops and away from wild waterbirds. Pastures, yards, ponds, and equipment easily become contaminated with HPAI virus from infected wild birds. Although humans are unlikely to become infected with avian influenza, humans can inadvertently move HPAI-contaminated material into contact with domestic birds through use of contaminated equipment, clothing and footwear, and vehicle tires.

More information on HPAI, biosecurity, and reporting sick or dead birds is available in multiple languages at or by calling the Massachusetts Department of Agricultural Resources at 617-626-1795.
