H5N1 Infects 47 Dairy Herds in 3 States as Indiana Duck Farm Logs June’s Only Commercial Outbreak

1 articles · Updated · meatingplace.com · Jul 3

Summary

  • 47 dairy herds were confirmed with H5N1 in June—40 in Idaho, six in Utah and one in Texas—marking a Mountain West resurgence after the virus reappeared in Idaho in April.
  • The poultry side was far quieter: a 3,100-duck commercial farm in Elkhart, Indiana, was the only confirmed commercial flock outbreak in the United States and Canada during June.
  • APHIS also confirmed June detections in a live bird market in Delaware County, Pennsylvania, and six backyard mixed-species flocks across four states involving more than 23,000 birds.
  • Even with the renewed cattle spread, dairy outbreaks in the first half of 2026 remain on pace to stay well below 2025 levels and far under 2024, when H5N1 was first confirmed in cattle.
