Pig culling operation on Yuen Long pig farm with pigs found with ASF virus completed
Friday, December 15, 2023

Regarding the incident announced on December 9 where samples of pigs from a Yuen Long pig farm tested positive for African Swine Fever (ASF), the Agriculture, Fisheries and Conservation Department (AFCD) launched a culling operation on December 12 on the farm concerned. The operation was completed today (December 15).

An AFCD spokesman said, "According to the contingency plan on ASF, the AFCD has sent staff to cull and handle a total of 949 pigs on the licensed farm in San Tin, Yuen Long, since December 12. The operation was completed today. All culled and handled pigs were sent to the West New Territories Landfill for dumping according to established procedures."

The spokesman further said, "The AFCD will arrange thorough cleaning and disinfection of the farm, and has notified the World Organisation for Animal Health of this incident. An investigation and tracing of the source of the virus in collaboration with international experts are underway."

Regarding the eight pig farms within three kilometres of the index farm, transport of any pigs from them is still suspended for the sake of prudence. No reports of abnormalities have been received from these pig farms so far. The AFCD will arrange veterinary inspection of these eight pig farms and collect further samples from pigs for ASF virus testing. If no abnormal health condition is noted on the pigs and all samples have tested negative for the ASF virus, pigs on these eight pig farms would be allowed to be transported to slaughterhouses.

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 pigs. Meanwhile, AFCD staff are currently inspecting all local licensed pig farms to ensure biosecurity measures have been properly implemented.

The spokesman stressed that ASF is not a zoonotic disease and will not infect humans, hence does not cause any food safety risk. Pork cooked thoroughly is safe for consumption. Members of the public do not need to be concerned. The incident does not affect the operation of local slaughterhouses nor the overall supply of live pigs.
