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].On 3 September, MARA and Ministry of finance jointly released a notice [2019] no.69 on Stabilizing pig production and ensuring market supply. This included: 1) subsidy for mandatory culling due to ASF, 2) facilitate temporary loans for breeding and large-scale pig farms, 3) increase incentives to move pigs outside counties (especially to support development of pig production, prevention and control of animal diseases, and construction of infrastructure for circulation), 4) improve insurance coverage of pigs, 5) Support policies for implementing improved pig breeding. Support for major pig breeding counties, purchase and use of elite pig semen with artificial insemination technology; at the same time, major livestock producer counties to support construction of wash and decontamination centres for pig transport vehicles, and 6) strengthen provincial financial coordination [reference]; on 5 September, MARA released a notice [2019] no.11 on “strengthening agricultural machinery purchase to support pig production development” to support pig farmers introducing machineries and increase biosecurity and farm size [reference]. On 10 September, the State Council issued the “Opinions on stable, and transformation and upgrade of pig production” ([2019] no.44, hereinafter the "Opinions"), which was drafted by MARA, together with the Ministries of Finance, Natural Resources, Ecology and Environment, Transport, the National Development and Reform, and the Banking and Insurance Regulatory Commissions, and the State Administration for Market Regulation, in accordance with the decision of the Party Central Committee and the State Council. The Opinion sets three measurable objectives: pork self-sufficiency rate, pig farm up-sizing rate, and comprehensive utilization rate of manure from the large farms. Emphasizing the people's governments of all provinces (autonomous regions and municipalities) bear the overall responsibility for stable pig production and market supply in the region, the "Opinions" put forward six specific policy measures: 1) guiding principles, development goals, responsibility, 2) stabilize pig production (accelerate recovery, standardize demarcation of no-pig-farming area, transportation of breeding pigs, piglets and pig products, ASF prevention and control, monitoring pig production and sales, improve market regulation mechanism), 3) accelerate the construction of modern farming systems (vigorously develop standardized large-scale farming, promote the development of small and medium-sized pig farms, scientific and technological pig production, utilization of aquaculture waste resources, increase support for the major live pig production areas), 4) improve the animal disease prevention and control system (enhance the ability, strengthening the detection and animal quarantine, develop grassroots animal epidemic prevention teams), 5) improve modern pig circulation system (upgrade slaughter industry, reform traditional pig transport, construct cold chain logistics infrastructure), 6) strengthen policy measures (financial policy support, guarantee land for pig raising, implementation of rules and regulations). For the long-term, the Opinions put forward three major systems to accelerate: modern breeding systems, disease prevention and control system, and modernized pig circulation system. Policy support will be provided from three aspects: increasing financial policy support, ensuring land for pig breeding, and strengthening rules and regulations, to accelerate transformation and upgrading of the pig industry to improve overall production capacity [reference1, reference2, reference3].

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]. 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 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 its new guidance (No.3708/HD-BNN-TY, 28 May) on slaughtering pigs and consumption of pig products. The Prime Minister released a Directive (No.42/NQ-CP, 18 June), which includes: 1) support households, small and medium-sized enterprises keeping grandparent pigs with VND 500,000 /pig (approx. 21 USD/pig) ; 2) support pig raising farmers and enterprises whose pigs are destroyed on the basis of price and pig raising costs suitable for each type of pig; higher support levels for sows and boars; 3) support small and medium enterprises but not exceeding 30% of losses due to epidemics. MARD issued a guidance (No.4178/HD-BNN-TY, 14 June) on Handling and disposal of African swine fever-infected pigs by incineration, and another (No.4249/HD-BNN-TY, 18 June) on Control of transportation of pigs for breeding and commercial farming in and outside ASF areas. 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.
On 27 August, the National Steering Committee on ASF Control released an instruction to stop throwing ASF infected dead, sick and suspected sick pigs to environment, violating regulations of animal health law and orders from Prime Minister and Minister of Agriculture [reference].

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. The same measures have been applied in reported ASF outbreaks e.g. stamping out, disposal and disinfection in affected villages. Further investigations and case finding are carried out in neighbouring areas. On 31 July 2019, the Cambodian Prime Minister issued a Circular on preventive measures of illegal imports of pig and all kinds of pork originated products. The Circular directed Ministry of Agriculture, Forestry and Fisheries, Ministry of Interior and Ministry of 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].


 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.
