 Situation update

Democratic People’s Republic of Korea

The Ministry of Agriculture confirmed its first ASF outbreak in Chagang-Do occurred on 23 May 2019 [reference]. The Ministry of Unification of the Republic of Korea proposed Democratic People’s Republic of Korea to discuss how to work together in controlling ASF [reference].



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, 138 ASF outbreaks detected in 32 Provinces/Autonomous Regions/Municipalities/Special Administrative Region. 1,133,000 pigs have been culled in an effort to halt further spread.


Hong Kong Special Administrative Region: ASF virus was again detected in a sample collected from one pig died at Sheung Shui Slaughterhouse (SSSH) with ASF suspected clinical signs. The pig was from a farm in Miezhou City, Guangdong Province [reference].


Guizhou Province: A vehicle transporting pigs into Guizhou Province without official animal health certificate was intercepted on 30 May about 10 kilometers from the Guixin Expressway Duyun south exit, Duyun City, Qiannan Buyei and Miao Autonomous Prefecture; 1 of 32 pigs on the vehicle was sick and died. Samples collected from the pig(s) tested positive for ASF [reference1, reference2].



Since its first report on 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 54 provinces/cities reported outbreaks, more than 2,200,000 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 2400 pigs have died or been culled.


Actions taken by China


MARA released the 2019 edition of the ‘ASF Epidemic Emergency Implementation Plan’ [reference]. MARA updated regulations on pig slaughterhouses: It task pig slaughter enterprises to conduct self-inspection by using PCR. If ASF is detected, the slaughtering enterprise should stop production for 48 hours, then apply for evaluation to resume production [reference].

Following assessment, Epidemic Zone was lifted on 28 and 29 May in Yecheng County and Shule County, Kashi District, Xinjiang Uygur Autonomous Region respectively [reference], and on 3 June in Shangri-La City, Diqing Prefecture, Yunnan Province [reference], as there were no new cases reported in the affected areas for 6 weeks.


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]. On 20 March, 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 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]. The Prime Minister released a Directive (No. 4291 / VPCP-NN, 17 May) o review ASF response plans [reference]. The Central Committee of the Communist Party issued the Directive (No. 34-CT/TW, 20 May) to strengthen their leadership and operational instructions for effective implementation of ASF response, control and prevention, one of the directive priorities is setting criteria to restore pigs after an outbreak, to strengthen veterinary system and capacity to be able to carry out the tasks and to strengthen inspection [reference]. MARD issued its new guidance (3708/HD-BNN-TY, 28 May) on slaughtering pigs and consumption of pig products [reference].

 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.
