 Situation update

Since the China Ministry of Agriculture and Rural Affairs (MoARA) onfirmed its first African swine fever (ASF) outbreak in Liaoning Province on 3 August 2018, ASF was detected in 27 sites (farms/abattoirs) in 8 provinces/Autonomous Region. More than 90,000 pigs have been culled in an effort to halt further spread.

Actions taken by China

Currently, live pig markets in infected provinces are closed; movement of live pig and pork products from infected provinces is prohibited [reference]. The government set a 3 km epidemic zone and a 10 km buffer zone around the epidemic zone. Since 3 August through 15 September 2018, 1,779,000,000 pigs and 39,084,300 places (including farms, markets, slaughterhouses, disposal sites, etc.) have been inspected nationwide.

25 September 2018: the Chinese State Council Executive Meeting issued the following requirements: i) Local governments should bear the overall responsibility of ASF prevention and control within their jurisdiction, in particular, strengthening supervision and strictly implementing measures such as culling, disinfection and harmless treatment. Swill feeding to pigs is forbidden in the ASF affected and adjacent provinces. More efforts should be made to investigate and track the source of outbreaks, as well as to strictly adhere to the monitoring and reporting system, ii) the central government will provide financial support to strengthen the supervision of pig transportation and inspection of pigs, to guarantee the supply of pork and ensure food safety (ref1, ref2).

21 September 2018: MoARA held a meeting on prevention and control of ASF and urged veterinary authorities at different levels to strictly implement various measures, especially during the Mid-Autumn festival and the National Day (24 September and 1 October 2018 respectively) – which mark the peak consumption of pork, emphasizing the need to strengthen market supervision and to ensure sufficient market circulation of pigs as well as adequate supply of meat and stable prices (reference). 

18 September 2018: Shandong Province released “An open letter on prevention and control of African swine fever” in response to the above notice, calling for the (i) suspension of inter-provincial transport of live pigs, (ii) prohibition of collection from, transport of or purchase of food waste from food industries and (iii) prohibition of feeding swill to pigs (reference).

11 September 2018: MoARA issued a "Notice on further strengthening control of inter-provincial transportation of pigs and their products”, calling for (i) temporary suspension of inter-provincial transport of live pigs from the provinces adjacent to ASF-affected provinces, (ii) closure of live pig markets within the adjacent provinces; (iii) strict implementation of animal quarantine e-certificate systems; (iv) 24-hour inter-provincial animal health inspection; (v) enhanced cooperation on control of pig transport by road. For 55% of the approximately 450 million pigs in China, 27% in unaffected provinces and 28% in affected provinces, transport across provincial borders is suspended (reference, National Bureau of Statistics, 2016).


 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) based on the principles of early warning, detection and notification, early reaction, and coordination. It needs to be reviewed periodically in relation to changing disease situation.
  • Application of strict biosecurity measures, frequently clean and disinfect farms, transport vehicles, and improved husbandry practices and production systems.
  • Strengthen surveillance and monitor 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 to locate animals in the event of outbreaks and animal health interventions.
  • Prohibition of swill feeding.
  • Strengthen proper disposal of food waste (food services, airports, seaports), which may contain uncooked pork products.
  • Sustainable outbreak control strategies must be in place. The strategies need to be developed in consultation with the private sector (pig production and allied industries, such as transport, feed operators) who should be actively involved in disease management options.

National Considerations, Inter-Regional Collaboration and Solidarity

  • Strengthening intraregional networks on disease management and diagnostic protocols.
  • Understand pig and pork value chains within the country and with neighbouring countries is essential for improved risk management.

 FAO’s actions

  • FAO organized an “Emergency Regional Consultation on African Swine Fever on Risk Reduction and Preparedness” in Bangkok, 5-7 September 2018 [reference].
  • FAO is in contact with authorities in neighbouring countries, to raise the importance of preparedness to respond to the threat of further spread.
  • The FAO Manual on ASF Detection and Diagnosis was translated into Chinese in collaboration with veterinary authorities and ASF national reference laboratory in China, and distributed [reference].
  • FAO mission to Mongolia and China (16-23 April 2018) to explore the feasibility of wild boar surveillance. Following the mission an awareness pamphlet was produced and delivered to herders/hunters and some rangers in the provinces that border with Russian Federation. 
  • FAO warned of the risk of ASF spread in Asia and urged regional collaboration including stronger monitoring and preparedness measures [reference].
