## Executive Summary
Health officials issue urgent warnings against raw milk consumption following the detection of H5N1 bird flu in a Central Washington dairy herd.

## Intelligence Brief
Health officials have issued warnings against the consumption of raw milk after highly pathogenic avian influenza (HPAI) was detected in a dairy herd located in Central Washington. Specifically, the Washington State Department of Agriculture (WSDA) has confirmed the presence of the virus in a herd within Benton County. This marks the first time that bird flu has been identified in a dairy operation within the Tri-Cities area. Consequently, officials have declared that raw milk is unsafe for consumption in light of these findings. Coverage of the situation is being led by several regional and specialized outlets.


The Seattle Times and the Tri-City Herald are reporting on the warnings issued to the public regarding the safety of raw milk. Simultaneously, technical reporting from the Avian Flu Diary highlights a significant trend in the state, noting that H5N1 detections in cattle across Washington have tripled, reaching a total of 27 cases. Further reporting from Dairy Herd indicates that this is part of a broader regional spread, noting that three different states have seen new HPAI cases emerge over the past 30 days. This development is critical because it demonstrates the expanding reach of H5N1 into livestock populations that were not previously the primary focus of avian flu outbreaks. The confirmation by the WSDA in Benton County underscores the volatility of the virus as it moves through dairy herds.


The shift from avian populations to cattle requires a reassessment of food safety protocols, particularly regarding unpasteurized products. The fact that detections in Washington cattle have now reached 27 indicates a growing localized epidemic that threatens agricultural stability. Future attention will likely focus on whether additional herds in the Tri-Cities area or other parts of Central Washington test positive for the virus. Monitoring will continue as officials track the spread of HPAI across the three states that have reported new cases in the last month. Stakeholders are watching for further updates from the WSDA regarding the status of the Benton County herd and any new directives concerning the safety of the dairy supply chain as the number of cattle detections continues to climb.
