Wisconsin Confirms First H5N1 Case in Dairy Cattle in Dodge County

Officials maintain the commercial milk supply remains safe due to pasteurization.

Overview

  • Two milk samples from the Dodge County farm tested positive on Thursday and Friday, with both results confirmed by the National Veterinary Services Laboratory.
  • The farm is under quarantine, ill cattle are being isolated for treatment, and state and federal teams are reviewing biosecurity and monitoring workers for flu-like symptoms.
  • The herd had previously returned five negative tests and showed minimal clinical signs, according to Wisconsin State Veterinarian Dr. Darlene Konkle.
  • The USDA says milk from affected animals is diverted or destroyed so it does not enter the food supply, and the CDC assesses the human health risk as low.
  • DATCP urges livestock owners to register premises, and a federal order requires testing for interstate cattle movement and reporting of positive Influenza A results.
