# APHIS Now Thinks Wild Birds Are to Blame for Highly Pathogenic Avian Influenza's Arrival on Four U.S. Dairies - AgWeb

> USDA APHIS now believes wild migratory birds introduced highly pathogenic avian influenza to four US dairy farms. Additional testing, including viral genome sequencing, is ongoing, and officials say there is no change that would make the virus more transmissible to humans.

## Why it matters

Attribution to wild birds suggests ongoing spillover risk rather than herd-to-herd spread, so the effect on milk supply is likely limited. Feed prices are not directly affected.
