USDA secretary not ready to declare bird flu threat over despite no new cases in over a month

U.S. Agriculture Secretary Tom Vilsack said Monday that he’s not ready to declare the Midwest bird flu outbreak over even though no new cases of the H5N2 virus have been detected over for over a month. Poultry producers have caught a break thanks to the summer weather because warmer temperatures tend to kill the virus, Vilsack said in an interview with The Associated Press, but the threat hasn’t passed.
