African swine fever was discovered at Sheung Shui slaughterhouse in the New Territories, an area bordering China’s southern province of Guangdong, in late May.
The Hong Kong government has indicated that the pig came from a farm in Meichow, a city in the northeast of Guangdong province. A cull of 4,159 animals has been ordered and the slaughterhouse was closed on May 31 for disinfection.
Government compensation for the cull is expected to reach USD$2.3 million.
China has suspended all live pig shipments to Hong Kong.
The first reported case of ASF in Hong Kong was confirmed on May 10, prompting a cull of more than 6,000 pigs to prevent the spread of the virus.
