Bird flu suspected in geese and swan deaths in Plymouth

A bird flu outbreak is likely responsible for the deaths of more than 60 Canada geese, swans and other birds in Plymouth, state officials announced as they urged Massachusetts residents to avoid handling sick or dead animals.

Public health and environmental officials said Sunday that they "suspect" an outbreak of the Highly Pathogenic Avian Influenza has led to the wildlife deaths at the 285-acre pond known as Billington Sea in Plymouth. There have been smaller suspected HPAI outbreaks at other undisclosed Massachusetts locations in recent weeks, which officials said affected less than 15 geese at each site.

People who observe at least five dead or sick wild birds in a single location are urged to notify the state. Officials say "prompt reporting" will speed up testing and diagnoses. The public should also report sick or dead domesticated birds to the Massachusetts Department of Agricultural Resources by calling 617-626-1795.

Officials say HPAI infections can occur in wild and domesticated birds, though raptors, waterfowl and other aquatic birds are at greatest risk. Wild animals that scavenge on birds can also become infected, such as foxes.

Human HPAI infections are rare, but people who have "prolonged close contact" with sick or dead birds face the greatest risk of getting infected. Pet owners in areas experiencing HPAI outbreaks should keep their animals indoors and away from wildlife, officials recommend.
