Actions taken by China


MARA task pig slaughter enterprises to conduct self-inspection by using PCR [reference1]. MARA released “Technical guideline for restocking of the African swine fever affected pig farms” on 10 September 2019 [reference2] and the “three-year action plan to accelerate the recovery and development of pig production” in December 2019, aiming to stabilise pork market and to recover production capacity. The action plan differentiate areas into a) Production area, b) Consumption area, c) Megacities, and d) balanced area, and promote implementation of the most appropriate method for the area [reference3, reference4]. To stabilize production and supply of pigs, based on the three-year action plan, MARA will strengthen ASF surveillance reporting, supervise entire swine industry value chain, control swill feeding, continue piloting prevention and control by region, timely provision of depopulation subsidies, accelerate ASF vaccine research, promote standardization and large scale pig farming, machineries for pig production, formulate guidelines for mechanization of animal husbandry, strengthen laws and regulations in rural agriculture, and accelerate the revision of animal quarantine regulations [reference5]. On 29 February, MARA released the 2020 edition of the ‘ASF Epidemic Emergency Implementation Plan’ [reference6]. 1) Changed the compensation for culling when ASF was found during transportation if the inspection certificate of origin could be provided; the cost to be shared between places where the outbreak occurred and the place of origin; the outbreak be counted by the place of origin, 2) reduced the number of days used to determine the outbreak response level from 30 days to 21 days, 3) redefined the definition of the epidemic site, i.e. when one single pigsty in a commercial farm with good biosecurity could be effectively isolated from other pigsty, this single pigsty could be identified as the epidemic site. Otherwise, the whole farm was an epidemic site. 4) expanded epidemiological investigation including not only outbreak investigation, but also presence of susceptible animals in the area, tracking and tracing of animals, products as well as other possible fomites for 21 days prior to the outbreak, 5) allowed qualified ASF negative farms to sell their pigs to a qualified slaughtering enterprise in a ‘point to point’ transportation within the affected province, and allowed breeding pigs and suckling pigs move within the province, and 6) revised the measures for dismissing lockdown and resume production for farms, slaughter house and markets in infected zone and control zones; the 2019 edition of the plan was abolished [reference7].

Actions taken by the Republic of Korea


 The Minister of Agriculture, Food and Rural Affair requested to the Ministry of Environment to install the 3rd stage wide fences after detecting wild boar cases outside of the wide fence area. The Minister also requested to take additional measure for the first and the second wide fence area, especially those areas using geographical barrier. Pig farms within 10km radius from a location where a positive wild boar case was detected will be tested for environment samples for ASF every week [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 ASF response, control and prevention. National Steering Committee for ASF prevention and control requested National Steering Committee against smuggling and People's Committees of provinces to conduct measures to prevent, promptly detect and strictly handle cases of smuggling, illegal transportation, trafficking of animals, animal products, especially pigs and pig products into Viet Nam (No.10/BCDDTLCP, 16 October). On 19 December 2019, MARD released 3 notices concerning restocking procedure (No.13/BCĐDTLCP), transport procedure for breeding pigs and well processed pork products (No.14/BCĐDTLCP), and promoting pig production and biosafety, as well as production other animals, poultry and aquaculture (No.9523/BNN-TY), and a letter to livestock producers (No.9524/BNN-TY) recommending 1. minimize the risk of disease recurrence in accordance with current regulations and No.13/BCĐDTLCP on restocking; 2. strict application of biosecurity, 3. avoid hoarding to ensure price stability; 4. not be involved in illegal trading of pigs or slaughtered pigs across the Vietnam border [reference].


Actions taken by Cambodia


Cambodia implemented movement control of live pigs, pork and pork products, stamping out, disposal and disinfection in affected villages. Further investigations have been carried out in neighbouring areas. The authorities are strengthening farm biosecurity and testing animals at slaughterhouses [reference].


Actions taken by Lao People’s Democratic Republic


The Ministry designates Red Area around an outbreak, to control the movement of pig and pork products, and prohibits pork consumption; and yellow Area (3 km radius from the red areas) as designated surveillance zones.


Actions taken by the Philippines


The Philippines has been implementing its 1-7-10 protocol to manage, contain and control the spread of the disease. Zoning was introduced to divide the country into Free Zone and Containment Zone, and the Containment Zone is further divided into infected zones, buffer zones, surveillance zones, and protected zones [reference2]. In Mindanao Island, the Regional Animal Disease Task Force was launched for Davao Region, enforcing strict 24/7 animal movement management, and conduct “trace-back” and “trace-forward” investigations [reference3, reference4, reference5]. On 7 February, the President Rodrigo R. Duterte issued Memorandum Order No. 22, ordering all government agencies and local government units (LGUs) to ensure the implementation of the nationwide zoning plan developed by the Department of Agriculture (DA) to control and contain the spread of ASF [reference6]. On 21 February, the President signed Executive Order No.105 to create a national task force, to prevent and control animal diseases such as ASF. The task force would be chaired by Agriculture Secretary with Health Secretary as vice-chair, other members include Secretaries of Executive, Interior, Environment, Trade, Finance, Budget, Social welfare and development, Foreign affairs, Transportation, Defence, Labour, Justice, Tourism, as well as Customs commissioner and Chief, Technical education and skills development. The national task force will 1) formulate policies, regulations and measures to address issues related to animal diseases; 2) develop a national risk reduction program and a comprehensive framework to fight against animal diseases. It will also supervise and monitor 3) the implementation of policies, regulations, measures and programs; 4) zoning and movement plans; and ensure compliance. It is also tasked to 5) develop and implement a national public awareness campaign on animal-borne disease; 6) develop programs such as financial aids, skill trainings to citizens affected by animal diseases; 7) revise contingency and action plans of emergent response for animal disease control; and 8) submit timely reports the status of animal disease [reference7].  The President instructed that pigs free of ASF should be branded to prevent further contamination and speed up the flow of pork and products in the country [reference8].


Actions taken by Indonesia


On 19 December, the Ministry of Agriculture (MoA) recommended the public to: isolate sick animals and equipment, and de-stock pig pens for 2 months; put pigs that died from ASF in a bag which must be buried immediately by officials; refrain from selling/consuming pigs/carcasses affected by ASF; and concluded that the main strategic steps to prevent ASF from occurring are through the application of biosecurity and good management of pig farms, as well as strict and intensive monitoring of high-risk areas. It advised provinces with high pig populations e.g. Nusa Tenggara Timur, North Sulawesi, West Kalimantan, South Sulawesi, Bali, Central Java, Central Sulawesi, Riau Islands, and Papua to be alert to the possibility of ASF disease. MoA suggested enhancing awareness raising with farmers and advocacy to local leaders regarding the ASF threat [reference1]. The Directorate General of Livestock and Animal Health Services (DG PKH) has formed 102 Emergency Posts with Rapid Response Teams at all levels, in response to the Minister of Agriculture Decree (No.820/Kpts/PK.32/M/12/2019, 12 December). ASF control in North Sumatra has been carried out in an integrated manner by a Joint Team involving regional agencies [reference2]. The Directorate General of Livestock and Animal Health Services (DGLAHS) deployed a team consisting of the Director of Animal Health, DGLAHS DIC Denpasar investigators, and NTT provincial animal health officials to investigate and contain the outbreak of increased sudden pig deaths in East Nusa Tenggara Province [reference3]. DGLAHS representatives requested regional pig producers to raise awareness of the possible spread of ASF and strengthen ASF surveillance along pig value chains between regions [reference4].


Actions taken by Timor-Leste


After the first ASF outbreak in Timor-Leste, the government formed a taskforce team from the Ministry of Agriculture and Fisheries (MAP), customs, Quarantine, Border Patrol Police, Immigration, and the Food Safety Authority (AIFAESA) to control African swine fever. MAP also implemented a movement ban of pig and pork products between districts [reference].


Additional news on unusual pig deaths


Papua New Guinea

A pig die-off has occurred in Southern Highlands Province. As of 29 February 2020, more than 300 pigs have died/sick of unknown cause. FAO is facilitating the National Agriculture and Quarantine Inspection Authority (NAQIA) to confirm the cause.


 FAO’s recommendations

ASF virus can be transmitted through pork and pork products (raw/frozen/dried/under-cooked) in which the virus can survive for a long time. Intensive customs control of passengers’ luggage is recommended during the high risk period from the end of December 2019 to the beginning of February 2020, covering Christmas, New Year, Lunar New Year holidays. Warning signs should be placed clearly at the border/customs entry including air ports and sea ports, stating the consequences of bringing pork and pork products from ASF-infected countries/regions, and instructing passengers to discard pork products in designated disposal places or to hand over to the customs personnel.


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.
