Democratic People’s Republic of Korea

The Ministry of Agriculture confirmed the occurrence of the first ASF outbreak in Chagang-Do on 23 May 2019 [reference].


Republic of Korea

The Ministry of Agriculture, Food and Rural Affairs (MAFRA) confirmed the occurrence of the first ASF outbreak in Gyeounggi-Do on 17 September 2019 [reference1]. A day after, additional outbreak was reported on a farm within 50km; both outbreak farms were located within 10 km from the Demilitarized Zone. More than 10,000 pigs have been destroyed due to the ASF [reference2, reference3, reference4]. Emergency measures implemented include: ban on pig movement from Gyeonggi-do to other provinces for a week; swill feeding has been prohibited nationwide; a nationwide standstill order for pig farms, slaughterhouses, feed mills, and related transport vehicles was implemented from 17 September 2019 06:30 for 48 hours, to check and disinfect 6,300 pig farms; and together with the Ministry of Environment, will estimate the wild boar populations in the 14 cities / counties along the border. Epidemiological investigation revealed that the infected farms had a total of 507 epidemiologically related sites across 5 provinces: i) Paju outbreak - 328 locations (Gyeonggi 251, Gangwon 60, Chungnam 13, other 4); ii) Yeoncheon outbreak - 179 places (Gyeonggi 147, Gangwon 15, Chungnam 6, Jeonnam 4, Gyeongbuk 3, other 4). Six high-risk cities/counties including Gimpo, Pocheon, Dongducheon, Cheorwon, Paju and Yeoncheon are designated as the 'ASF Critical Control Area'; the ban on pig movement from 'ASF Critical Control Area' to other area was extended to three weeks except slaughter only at designated slaughterhouses; entry of those who have frequent contact with pigs (veterinarians, personnel from feed company, etc) to pig farms in Gyeonggi-Gangwon area will be restricted except for the purpose of treating the sick animals [reference5, reference6].

Actions taken by China


MARA released the 2019 edition of the ‘ASF Epidemic Emergency Implementation Plan’ [reference]. MARA updated regulations on pig slaughterhouses: It tasks 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]. In order to strengthen ASF prevention and control measures MARA released a notice on the special action for "cleaning and disinfection" on 6 September to organize special campaign "comprehensive cleaning and disinfection" to reduce the risk of disease outbreak and spread of virus. The notice includes: 1) Awareness on the importance of cleaning and disinfection, 2) All provinces/autonomous regions/ municipalities to organize “great cleaning and disinfection” special campaign before the end of October, 3) Strengthen cleaning and disinfection measures in high-risk areas. According to administrative and media reports, there are problems of discarding and burying dead pigs in some places. All areas should increase the intensity and implement thorough cleaning and disinfection to farms where pigs have died abnormally, sites where pigs are discarded or privately buried, 4) Guide and supervise disease control body on cleaning and disinfection measures, 5) Strengthen technical training and material reserves. The China Animal Disease Prevention and Control Center and the China Animal Health and Epidemiology Center should provide technical guidance on cleaning and disinfection work in various places [reference].

Actions taken by Viet Nam


Viet Nam has implemented movement control of pigs and pig products from affected communes. 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. MARD issued a guidance on Handling and disposal of African swine fever-infected pigs by incineration (No.4178/HD-BNN-TY, 14 June), and on Control of transportation of pigs for breeding and commercial farming in and outside ASF areas (No.4249/HD-BNN-TY, 18 June). In case of pig transportation into and out of epidemic areas located in provincial localities, these pigs have to show negative test results for ASF. If pigs originate from other provincial localities, in addition to negative test results shown for ASF, pigs have to be quarantined and granted quarantine certificates for transportation out of the provincial localities. For pig transportation across epidemic areas, apart from above, notify localities of the pig transportation roadmap. Means of transport have to follow the routes as guided by the veterinary management agency of localities which pig transporting means travel across.

Actions taken by Cambodia


Cambodia has implemented movement control of live pigs, pork and pork products for the Kampoul Serey and Soay Village, Mean Commune, Oraing Ov district, Tbong Khmum Province; and stamping out, disposal and disinfection in affected villages. Further investigations have been carried out in neighbouring areas. On 31 July 2019, the Prime Minister issued a Circular directed Ministries of Agriculture, Forestry and Fisheries, Interior, and Economy and Finance to take urgent and necessary measures for prevention and control of ASF in the country and from neighbouring countries. The authorities are strengthening farm biosecurity and testing animals at slaughterhouses [reference].

Thailand: Unconfirmed information about death of two pigs in a district of Chiang Rai, only 20 km from Myanmar [reference1, reference2].


 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.
