Washington State reported three additional H5N1-infected dairy herds—two in Yakima County and one in Benton County—bringing the total reported since early October to 43. The text also reports three human infections, including one death, and says no human-to-human transmission has been identified in the United States.
Infected dairy herds can face movement controls and production disruption, which may constrain milk supply locally. Wider dairy-market effects depend on the scale of restrictions and spread.
