"Scientists Call for Improved Response to Human-To-Human Spread of Bird Flu"
Federal authorities have downplayed the impact of bird flu outbreaks on dairy farms, but recent evidence suggests that the virus is spreading among cows and from cows to poultry. The U.S.D.A. has not publicly shared information about bird flu infections in asymptomatic cattle, and testing for H5N1 infection has been limited. Scientists fault the federal response for not actively monitoring infections in pigs and not sharing enough genetic information about the virus, raising concerns about the safety of the nation's milk and food supply.
