JAMA reports that H5N1 avian influenza has spread widely among US dairy cattle, with the virus detected in herds across multiple states. Viral material was also found in commercial milk, though pasteurization inactivates the virus.
Public health officials are raising concerns about the outbreak's reach.
Infected herds reduce milk output and raise dairy herd management costs, which can support milk prices. Wider spread could also tighten dairy supply and affect cull cow and feed demand.
