Taiwan reported its first cases of African swine fever on a farm in Taichung, prompting the culling of 195 pigs and a five-day ban on pig movement and slaughter across the island.

Authorities established a 3-kilometer control zone around the farm and carried out disinfection measures, while Agriculture Minister Chen Junne-jih said the virus strain will be isolated before reporting to the World Organization of Animal Health.

African swine fever is nearly always fatal to pigs but does not affect humans or other animals outside the pig family.

Officials suspect the virus was introduced through illegally imported pork products entering farms via food waste, the AP has reported.

Taiwan’s measures follow similar outbreaks in China and Vietnam in 2019, while South Korea and twelve European countries currently also face ongoing cases.
