MARA released the 2019 edition of the ‘ASF Epidemic Emergency Implementation Plan’ [reference1]. 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 [reference2]. MARA released a comprehensive “Technical guideline for restocking of the African swine fever affected pig farms” on 10 September 2019 [reference3]. MARA released the “three-year action plan to accelerate the recovery and development of pig production” on 4 December. The plan aims to stabilise pork market and to recover production capacity. It 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 [reference4, reference5]. As of 17 January 2020, the National Bureau of Statistics released that the pork output in 2019 was 42.55 million tons, a decrease of 21.3% compared with 2018 [reference6].

Actions taken by the Republic of Korea


To prevent ASF spread to southern parts of the country, MAFRA an enhanced emergency measure reinforcement including installation of wide-area fence from west to east side of the country to block wild boars [reference1]. Joint teams of officials from MAFRA and Animal and Plant Quarantine Agency (APQA) are monitoring and inspecting pig farms in the northern part of Gyeonggi-do and Gangwon-do. As soon as wild boar case confirmed, MAFRA sent emergency alert SMS to all pig farmers in both provinces to enhance farm biosecurity through disinfection on the farm and surrounding area [reference2]. Expecting an increase number of tourists during the lunar New Year, the MAFRA tighten the customs control over the portable goods from tourists in the ports of entry (ports and airports) until the end of January and planned to conduct the public awareness campaigns for travellers leaving the country [reference3].

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 i.e. all pigs within 1-kilometer radius of infected farms will be culled; limit animal movement and swine farms will be under strict surveillance and testing within a 7-kilometer radius; swine farms within a 10-kilometer radius will be required to submit a mandatory report on the disease [reference1]. The country has started zoning, is divided into Free Zone and Containment Zone (the Containment Zone is further divided into infected zones, buffer zones, surveillance zones, and protected zones [refrence2].


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 (the Rapid Response Team, the Medan Veterinary Service, the Provincial Food Safety and Livestock Service, the Office of Public Works, the Health Service and the Police) [reference2]. On 30 December, the MoA and the Regional Government of Humbang Hasundutan Regency, North Sumatra Province collaborated in conducting a "Safe and Healthy Pork Eating Campaign", advising that ASF was not a zoonotic disease , and pork and its products were safe for consumption [reference3]. The government through the MoA has also allocated a budget of IDR 5 billion (US$ 357,938) to support ASF control, carcass disposal and containing the spread of the virus [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].


 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.
