Taiwan confirms first H5N1 poultry outbreak since 2018

Taiwan has confirmed its first H5N1 highly pathogenic avian influenza outbreak on the main island since 2018, prompting the culling of more than 2,600 guinea fowl. Authorities have strengthened surveillance and biosecurity measures as they prepare for increased avian influenza risk during the approaching winter season.

Taiwanese authorities have confirmed an outbreak of H5N1 highly pathogenic avian influenza at a poultry farm in Dayuan District, Taoyuan, marking the first detection on Taiwan proper since 2018.

The farm reported abnormal bird deaths on 23 September, prompting officials to collect samples and immediately impose movement restrictions. H5N1 was confirmed the following day.

Authorities subsequently culled 2,616 guinea fowl and disinfected the farm, surrounding roads and other potentially contaminated areas. Poultry holdings within a three-kilometre radius are also being inspected, with no evidence of further outbreaks reported so far.

The case comes as Taiwan strengthens its avian influenza preparedness ahead of the higher-risk winter period. Enhanced measures running until the end of March include increased farm surveillance, inspections of high-risk poultry operations, monitoring of migratory birds and additional disinfection in potential hotspots.

Authorities said the outbreak remains an isolated case and poultry production and supply have not been affected.

Farmers have been urged to immediately report abnormal mortality or declining feed intake, with penalties for failing to notify authorities of suspected disease.
