TAIPEI (Taiwan News) — Tainan’s Animal Health Inspection and Protection Office on Monday culled 10,836 laying hens at a farm in Houbi District after tests confirmed H5N1 avian influenza.

The city government said the farmer reported abnormal deaths on Thursday, prompting officials to impose movement controls, launch an outbreak investigation, and collect samples. Tests later came back positive after analysis by the Ministry of Agriculture’s veterinary laboratory.

Officials said all birds were culled, transported to an incinerator, and the entire farm disinfected to prevent further spread. Disease control measures were implemented the same day.

CNA reported Monday that authorities are sampling six poultry farms within a 1-kilometer radius and inspecting 47 more within 1 to 3 kilometers. Patrols, environmental cleanups, and disinfection vehicle deployments have also been stepped up to reduce virus levels.

Officials warned that migratory birds are heading north and sporadic bird flu cases continue to be reported across Taiwan. They said six cases have been confirmed nationwide so far this year, including one in Tainan, showing the virus remains present in the environment.

Farmers were urged to tighten entry controls and thoroughly clean and disinfect boots, vehicle tires, cages, and equipment. They were also told to repair damaged netting and promptly report illness or sudden deaths.

Liberty Times reported Monday that the Houbi egg-laying farm is Tainan’s first avian influenza case since last fall. Between December 2024 and January 2025, five avian influenza outbreaks were reported in the city.
