SOP for ASF

Standard Operation Procedure on ASF (August 2018)- Depopulation- Disinfection - Movement restriction- Outbreak investigation - Disposal- Command System

SOP for ASF

The main possible pathways of ASF introduction into Korea

- illegal imports of food products for private consumption

or small-scale trade

- swilling feeding from contaminated food waste

- cross-border movement of wild boars

Quarantine(1)

APQA has increased intervention at the border, targeting high risk products at the international airports, seaports and mailing process centers (Cooperation with Korea Custom Service)

Increased border activities

Quarantine(2) Since 2015, APQA has conducted testing on pork products confiscated at airports and seaports from travelers coming from countries affected by ASF

• A total 4,064 pork products were seized from travelers from China on August 2018, 52 products randomly selected and tested for ASFV, 2 pork products were contaminated with ASF virus fragment.

First ASF gene detected on 24 August 2018

Russia, Vietnam, Thailand, Mongol, Myanmar, China (8 positive)

Russia, Italy, Poland,Czech, China (4 positive, No virus isolation)

Year 2015 2016 2017 2018 2019(Jan-Mar)

Sample number 65 100 112 200 36

Positive number - - - 4 8

No. countries 8 7 9 5 6

Quarantine(3)

P54 gene (Gen bank MH717102) 100% identical to SY-18

Compare with SY-18 (China strain)

I73R-I329L gene (Gen bank MH717104)

100% identical to SY-18

Sequence Analysis p72

Figure. Phylogenic analysis of a detected ASFV gene. Neighbor-joining phylogenic tree was constructed using MEGA6.0 software

Genotype II

Sequence of PCR(2 pork products, August 2018) got 100% match to the strains in China

Biosecurity Farms Conduct on site inspection for pig farms

- Intensive monitoring for swill feeding farms* Number of swill feeding pig farms : 384 farms(May 2018) → 267(Jan 2019) ** Surveillance for all pigs in swill feeding farm(322 farms 2,478 pigs) Provide advice, recommendations Order and penalty to farmers who do not follow

the biosecurity standards

Feed manufacture from recycled food waste

* It must be registered and compliance with regulation(80°C, 30mins)** Ban on swill feeding of food waste from international aircraft and ships

Conduct on site inspection (Cooperation with Ministry of Environment)

Domestic pig population

Farms 6,188

Surveillance(1)

Passive surveillance

No reports on dead wild boars

No domestic pigs showing clinical signs compatible with ASF Domestic pigs showing swine fever-like syndrome

* 2019 plan( 1,400 farms / 11,200 pigs)

* 2019 plan( 2,000 by MAFRA, 800 by Ministry of Environment)** Cooperation with Ministry of National Defense & Environment (wild boars in DMZ) ***The wild boar density was estimated 5.6 head/100ha in 2017
