# Genetic sequencing links Washington dairy bird flu to Idaho

> USDA said genetic sequencing found H5N1 genotype B3.13 in two Washington dairy herds, consistent with transmission from Idaho, likely through cattle movement. The agency is conducting surveillance around the affected farms and elsewhere in Washington; affected milk is diverted or destroyed.

## Why it matters

Cattle movement can spread infection between dairy herds and prompt biosecurity controls, but officials said the detections do not affect the safety of the commercial milk supply. No material feed-commodity price effect is indicated.
