 Situation update


Since the China Ministry of Agriculture and Rural Affairs (MARA) confirmed its first African swine fever (ASF) outbreak in Liaoning Province on 3 August 2018, 129 ASF outbreaks detected in 31 Provinces/Autonomous Region/Municipalities. MARA reported on 23 April 2019 that 1,020,000 pigs have been culled in an effort to halt further spread.


Hainan Province: Additional ASF outbreaks occurred on one pig farming household in Xiuying District, Haikou City on 11 April, on two pig farms in Lingshui Li Autonomous County on 13 April, on two pig farming households in Chengmai County on 14 April, on one pig farming household in Baoting Li and Miao Autonomous County on 16 April; 252 of 252 pigs became sick of which 43 died, 34 of 86 pigs became sick and died, 62 of 172 pigs became sick and died, 7 of 7 pigs became sick and died from the disease, respectively [reference1, reference2].



Since its first report on the 15 January 2019, 11 outbreaks in 6 provinces and in Ulaanbaatar have been reported, involving 105 farms/households. More than 3,115 pigs, more than 10 percent of the total pig population in Mongolia, have died/been destroyed due to the ASF outbreaks.


Viet Nam

Since the Ministry of Agriculture and Rural Development (MARD) confirmed its ASF outbreaks on 19 February 2019, a total of 24 provinces/cities reported outbreaks, and more than 89,600 pigs have been culled.



Since the Ministry of Agriculture Forestry and Fisheries confirmed its first ASF outbreak in Som Kaninh village, Som Thom commune, O Ya Dav District, Ratanakiri Province on 2 April 2019, more than 1700 pigs have died or been culled.


Ratanakiri Province: additional ASF outbreaks have been confirmed in free ranging backyard pigs in Pok Yai (1) and Ya Tong (2) Communes, Ou Ya Dav District through surveillance around the initial outbreak [reference].


Actions taken by China


The government set a 3 km epidemic zone and a 10 km buffer zone around the epidemic zone. A strict movement control of live pigs was introduced, and live pig markets in infected provinces and adjacent provinces were closed [reference]. Studies showed that 62% of the first 21 ASF events in China were related to swill feeding. Directives on banning swill feeding to pigs and record keeping of livestock transportation vehicles was updated [reference]. Epidemiological studies of 68 outbreaks revealed 3 major causes spread ASF virus: 46% by vehicles and workers without disinfection, 34% by swill feeding, and 19% by transport of live pigs and their products across regions [reference]. As ASF was detected in a wild boar, MARA and Ministry of Natural Resources released a joint notice on “Strengthening the Joint Prevention and Control Work on ASF in domestic pigs and wild boars” [reference]. MARA released the 2019 edition of the ‘ASF Epidemic Emergency Implementation Plan’ [reference]. In March 2019, MARA updated regulations on pig slaughterhouses: before May 2019, provinces to conduct a through inspection of pig slaughtering enterprises without pollutant discharge permit, or does not meet the animal epidemic prevention requirements, shall immediately stop production and rectify before July 2019 to continue slaughter. It task pig slaughter enterprises to conduct self-inspection by using PCR, which to be implemented from April–July 2019. If ASF is detected, the slaughtering enterprise should stop production for 48 hours, then apply for evaluation to resume production. If ASF virus nucleic acid is detected in products that are sent out from a slaughterhouse due to a mal-conduct, the slaughter enterprises needs to recall the same batch, and the activities be suspended for at least 15 days [reference].

Actions taken by Viet Nam


Viet Nam has implemented movement control of pigs and pig products from affected communes; ASF positive farms have been depopulated according to the Action Plan for Emergency Response to ASF [reference]. MARD has proposed additional guidelines for ASF control in February for provincial authorities implementation [reference].On 20 March 2019, MARD requested provincial/city people’s committee to allow healthy pigs in infected area to be slaughtered for consumption within: infected commune; infected district if >1 communes infected; or provinces if >1 districts infected. No movement from infected provinces is allowed [reference]. The Prime Minister Office announced on 7 March 2019 the increase of compensation for piglets and fattening pigs to 80%, and x 1.5 – 2.0 of normal compensation rate for sow/boar [reference]. Advocacy on 5 NOs for sick/death pigs (No hiding, no trading, no slaughtering, no dumping carcass in the environment, and no unheated swill feeding) which has been emphasized since September 2018 is being strengthened.

Actions taken by Cambodia


Cambodia has implemented movement control of live pigs, pork and pork products within the affected district. Stamping out, disposal and disinfection were extended to some villages in other communes (Ya Tong commune and Pok Yay commune). Further investigations have been carried out in neighbouring areas.

 FAO’s recommendations

Countries of the region

  • Animal disease containment in its broadest sense should be prioritized within the highest levels of governments.
  • Preparedness (e.g. contingency planning, standard operating procedures— SOPs, secured financial support) for improved early warning, detection and notification, early reaction, and coordination needs to be in place and reviewed periodically in relation to changing disease situation.
  • Application of strict biosecurity measures specific to the different swine producing sectors including frequent cleaning and disinfection of farms, transport vehicles, and improved husbandry practices and production systems.
  • Strengthening surveillance and monitoring of transport of live pigs as well as pork products.
  • Good communication and coordination with swine producing commercial sector and swine famers are essential to strengthen cooperation in ASF prevention, detection, and control. Awareness and training of all stakeholders, from veterinarians to farmers, intermediaries and other value chain actors is needed.
  • Communication to public is to be in place to avoid the rumours leading to food safety perceptions and consumption disruption.
  • Farm registries, animal identification and censuses are essential to enable animal health interventions.
  • Prohibition of swill feeding where feasible; highly regulated where not.
  • Strengthening proper disposal of food waste (food services, airports, seaports), which may contain uncooked pork products.
  • Outbreak control strategies must be in place. The strategies need to be developed in consultation with the private sector (pig producers and allied industries, such as transport, feed operators) for improved disease management options and compliance.

National Considerations, Inter-Regional Collaboration and Solidarity

  • Strengthening intraregional networks on disease management and diagnostic protocols.
  • Understanding pig and pork value chains within the country and with neighbouring countries is essential for improved risk management.
