Overview

  • The Nebraska Department of Agriculture, working with USDA APHIS, confirmed highly pathogenic avian influenza in a central Nebraska dairy herd, marking the state’s first cattle case.
  • The herd is under quarantine, and National Veterinary Services Laboratories report the virus closely resembles a strain previously identified in California.
  • USDA said the detection followed required pre-movement milk surveillance, with sequencing consistent with H5N1 clade 2.3.4.4b genotype B3.13.
  • Since March 2024, more than 1,000 herds across 17 states have tested positive, and officials say the pace has slowed but transmission continues.
  • Officials say affected cattle typically recover with supportive care; the state veterinarian urges strict biosecurity, CDC assesses low public risk, and FDA affirms pasteurization keeps commercial milk safe.
