African Swine Fever
African Swine Fever (ASF) is a highly contagious disease in pigs which is caused by ASF double-stranded DNA virus. It is not a zoonotic disease and will not infect human, hence does not cause any food safety risk. However, ASF virus demonstrates extremely high potential of transboundary transmission and the mortality rate of pigs infected with ASF could reach 100%. In addition, currently there is neither vaccine nor drug available for prevention or treatment of ASF. Thus, ASF is severely threatening the pig farming sector and relevant industries anywhere as well as the overall live pig supply.
ASF virus possesses high survivability in blood, faeces and tissues of the infected pigs and can persist for a long time, especially in uncooked or undercooked pork products contaminated by ASF virus. Cold environment favours the survival of ASF virus for even longer. In order to prevent the incursion of ASF virus into local farms, the farmers must implement stringent biosecurity measures.

As of 28 January 2025, all the culling operations of the ASF-infected pig farms have been completed. All culled and handled pigs were sent to the West New Territories Landfill for dumping according to established procedures. The Agriculture, Fisheries and Conservation Department (AFCD) will arrange thorough cleaning and disinfection of those farms, and has notified the World Organisation for Animal Health of the incidents. An investigation and tracing of the source of the virus in collaboration with international experts are underway. As to the other pig farms, no reports of abnormalities have been received so far. The AFCD will continue to keep local pig farms under close surveillance, as well as conducting tests if necessary. The AFCD has also reminded all farmers to ensure biosecurity measures have been properly implemented and alert the Department immediately if an abnormal health condition is observed in the pigs.
