African Swine Fever
African swine fever is a severe viral disease of pigs that is highly contagious but does not infect humans and poses no food safety risk. According to the World Organization for Animal Health, African swine fever does not pose a threat to human health.
To reduce the risk of ASF intrusion into local pig population, control and surveillance at source are of utmost importance. All imported pigs delivered to slaughterhouses must come from registered pig farms supplying Hong Kong. Pigs have to be quarantined to ensure no signs of African swine fever before they are released. In addition, all pigs must be accompanied by a valid health certificate issued by the Mainland Customs.
