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.

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.

Officials said 500 to 1,000 wild bird deaths had been reported around the state, as well as a 30-bird flock of domestic poultry in Plymouth County.
