An earlier version of this story reported that the virus had been detected since then.) The number of bird flu cases in Central Massachusetts is relatively low, compared to a swath of the state that runs from Greater Boston to Southeastern Massachusetts.

Massachusetts officials announced Wednesday that bird flu is now considered to be “widespread” in the state and urged the public to avoid handling birds or other animals that are dead or appear sick.

The circulating bird flu has become “widespread” in Massachusetts, as officials believe the virus has killed 500 to 1,000 wild birds across the region.

As the bird flu continues to spread in the U.S., Massachusetts farmers must protect their flocks. But due to the recent rise in the disease, growing and raising their own food on property is a tradition that may have to be put on hold.

Evidence suggests that bird flu is widespread in Massachusetts and “likely present even in places where there has not been a confirmed positive,” state officials announced Wednesday.

State officials suspect the avian flu has killed dozens of wild birds in Boston, Amherst, and Plymouth, and farmers are stepping up precautions.

Officials said risk to humans remains low, but the state's public health veterinarian said pet cats are "very susceptible" to the bird flu and can become "seriously ill."

The leading message coming from Bay State officials this week was that people and pets should stay away from sick or dead wild birds. And if they see any, they should report their observations to MassWildlife.
