Here's what worries scientists about bird flu's spread among cattle
Briefly

The risk to humans from the bird flu outbreak in dairy cattle depends on the virus's ability to evolve and better infect mammals. Current data show unusual behavior in cattle with no significant respiratory symptoms.
High concentrations of the virus found in milk suggest mechanical transmission during milking as a possible spread method among cattle. Scientists are closely monitoring for any genome changes that may pose a threat.
