New Zealand is ready for a possible outbreak of highly pathogenic avian influenza (H5N1) following its detection in a wild seabird in Western Australia. Minister for Biosecurity and Food Safety Andrew Hoggard stated that various government departments have intensified monitoring and readiness measures. Geographical isolation has afforded New Zealand time to prepare since the global spread of the H5N1 bird flu strain.
Australia has identified the H5N1 2.3.4.4b bird flu strain in a migratory seabird in Western Australia, with a nearby giant petrel also under suspicion. Although no cases of poultry or mass deaths have been reported, New Zealand remains vigilant and in close communication with Australian authorities. The virus may enter through wild birds, and eradicating it from native populations could be challenging.
Minister Hoggard advised farmers, backyard poultry owners, and outdoor enthusiasts to enhance biosecurity and report any unusual bird clusters. He reassured that there is no threat to food safety, and the risk to human health is currently low. This marks the first confirmed case of the highly pathogenic strain on the Australian mainland, which has caused significant bird and animal fatalities worldwide since 2020.
A giant petrel found sick near the affected bird has been isolated for monitoring. Australia had previously allocated 113 million Australian dollars to prepare for a potential H5N1 outbreak. Authorities, including Threatened Species Commissioner Fiona Fraser, are closely monitoring to ascertain if the strain has established itself in any Australian populations. Australia was the last continent where the H5N1 bird flu strain had not been detected.
The H5N1 strain can rapidly spread among poultry and wild bird populations, although human cases linked to the disease are uncommon. The remote Australian territories of Heard and McDonald Islands reported the H5N1 strain last year, situated in the southern Indian Ocean.
