State officials say all 95 licensed farms with dairy herds have been tested for bird flu, and the results are 100-percent negative. 

The highly contagious bird flu has spread to at least 14 states, but the Department of Agricultural Resources says so far Massachusetts is in the clear. 

The state testing program is expected to be repeated on a regular basis, and officials believe it could serve as a national model.  The department says state farms follow strict safety protocols and produce the highest quality products.
