ASF arrived in the Soviet Union for the first time in 1977 through the seaport in Odessa ( now a port city of Unkrain).
-Contaminated food waste taken by pigs
Odessa1977
ASF was introduced into Georgia from southern Africa late in 2006, through the Black Sea Port of Poti.
-Contaminated food waste taken by pigs
2006-2007
疫情扩散到5个州
疫情扩散到10个国家

Other scenarios
1)Live suids import from countries with ASF endemic or risk
2)Pork or Pork products from the above countries
3)……
Summary of the ASF risks to Asia
• Wild boars from affected neighboring countries
• Food waste or garbage from international traffic (especially the seaports and airports)
• Suid product carried by international passengers, especially those from affected countries
• Smuggling of suids and suid products
• Importing of live suids and suid products from Africa or eastern Europe

China’s Status and Policies for ASF
Status and Policies for ASF
1. Free in record history
2. Research conducted since 1963
3. List A exotic animal diseases since 1978
4. Administrative Regulations on Animal and Plant Quarantine
for Export and Import,1982
5. Administrative Regulations on Animal Epidemic Prevention,
1985
6. Law on Animal and Plant Quarantine for Export and Import,1991
7. Law on Animal Epidemic PreventionIssued in 1997, revised in 2007, amended in 2013
History of Policies for ASF
8. National programs for training and surveillance since 2001
9. National Diagnostic Standard for ASF, published in 2002
10. Intensified program for training and active surveillance
since 2005
11. Risk assessment in 2007 following the Caucasian outbreaks
12. Draft contingency plan for ASF in 2007
13. Emergency response drills in 2007 and 2014
Key points of the policies and standards
1. How to prevent the introduction of ASFV
-Risk assessment of the exporting country
-Ban of the export of live suids and products from
countries affected or at risk
-Implement strict inspection measures before and after the
import from any other country
-Intensify border check for animal product smuggling
-Proper handling of waste from international traffic
2. How to find the suspects and confirm the outbreaks
-OIE standard
-National Standard
Key points of the policies and standards
3. How to report and handle a suspect or confirmed cases
-Laws and regulations
-Contingency Plan for ASF
-Prevention and Control standard for ASF
-Destroy all the infected herds or all suids in the
protection zone
-Close live pig markets in restricted areas
-Intensify active surveillance in restricted areas
-Movement control of the live pigs all over China
-Strengthen biosecurity in all pig farms
-Epidemiological Investigation and analysis
National ASF Emergency Plan and Technical standard for ASF prevention and control

All pigs of all herds serologicallly screened immediately after confirmation
Movement prohibited for 30 days
Depopulation of infected farm

4. How to keep and promote the capacity in recognizing and
handling the ASF outbreaks
-Financial and material reservation for emergency response
-Ongoing collection of ASF outbreak information
-Ongoing risk analysis
-Ongoing training programs
-Ongoing risk based surveillance
-Ongoing updating of the contingency plan
-Emergency response exercises

A short summary
1.China is trying its best to prevent the ASF coming into the Country
2.We are also preparing for the control and eradication in case ASF comes
Looking into the future
1. The FAO-CN TCP project will further our ability to confront the challenges from ASF
2. As a partner of the FAO/OIE GARA (Global African swine fever Research Alliance), we will continue to update our knowledge and share our experience in ASF research, prevention and control
3. The ongoing programs funded by Chinese government will help us to conduct more detailed risk analysis and risked based surveillance
4. More technical collaborations between China and foreign partners (especially the OIE reference labs) are needed in termsof Epidemiology and the development of vaccines and rapid pen-side tests
