The H5N1 avian flu outbreak in dairy herds is approaching the three-month mark, prompting the U.S. Department of Agriculture to emphasize the importance of biosecurity measures in containing the virus. Despite resources and support from the USDA, uptake has been low, with only four herds participating in a voluntary testing pilot program. The virus has infected 116 herds in 12 states, with evidence suggesting transmission through the milking process. While the risk to the general public is low, those working with dairy cows or consuming raw milk are at higher risk. Research shows the virus can remain infectious on surfaces in milking equipment.
