New Zealand contains bird flu to single site in Otago region
New Zealand authorities have announced that the recent outbreak of bird flu has been successfully contained to a single site in the southern Otago region.
The country's Ministry for Primary Industries confirmed that farms linked to the original site, which tested positive for avian influenza on December 1, 2024, have been declared free of the virus. This conclusion follows extensive testing conducted at the end of the full incubation period for the disease. Thousands of samples were tested to ensure the virus had not spread beyond the initial location.
The outbreak was first detected on an egg farm operated by Mainland Poultry. Testing identified the presence of a highly pathogenic H7N6 subtype of avian influenza, distinct from the H5N1 strain that has raised global concerns. The discovery prompted the immediate suspension of poultry exports, which represent an annual value of approximately NZD 190 million (US$107 million).
Authorities undertook a comprehensive testing effort, collecting around 4,300 samples from 36 flocks across five farms connected to the initial outbreak site. None of these samples returned positive results for avian influenza.
Chief Veterinary Officer Mary van Andel expressed confidence in the containment efforts, stating that the extensive testing provides assurance that the virus has been limited to the single property. She indicated that the situation is progressing towards the complete eradication of the disease.
Van Andel also noted that the successful completion of incubation-period testing would support ongoing negotiations with trading partners concerning New Zealand's poultry exports. While the export of most poultry products remains halted, some items that meet specific heat treatment requirements for bird flu are being shipped to Australia.
The ministry is collaborating with Mainland Poultry to determine an appropriate stand-down period for the affected property following decontamination. Additionally, efforts are underway to address compensation matters with the farmer impacted by the outbreak.
