Based on recent outbreaks in Korea FMD as a model system HPAI, Brucellosis, Rabies, BSE, etc. Control System Development Project

not finished yet

Commercialization in the near future

FMD - Foot and Mouth Disease

FMD is one of the most contagious animal diseases known. Key features:

Wide host range Multiple infection routes Small infective doses Short incubation period Virus excreted before disease is evident Persistence in ‘carriers’, products and environment

Ability to spread through movements of animals, people, products, equipment and by wind makes it difficult to control.

FMD Host Animals

Foot-and-Mouth Disease Virus

Picornaviridae Family, Aphtovirus genus Single-stranded (+ ) RNA 7 serotypes (O, A, C, Asia1, SAT1, 2, 3) I cosahedral structure containing 4 proteins I nactivated by pH < 6.0 or > 9.0

FMD (Foot and Mouse Disease) Virus

Ways of Spreading

Movement of infected animals

most important

Virus in animal products Contaminates Wind-borne spread Carrier animals

Airborne Virus Spreading

Factors Affecting Spreading Activity - Infection

Strain of virus Quantities of virus Degree/type of contact Susceptibility of recipient animals

FMD Spreading

Weather conditions

Under right conditions a plume can form -> long distances atmospheric stability (e.g. wind speed, cloud cover, sunlight)

Virus concentrations affected by plume dispersal and deposition Ground conditions (temperature, type, roughness)

Topography

More likely to occur over sea than land (all long distance spread (< 100 km over sea)

FMD OUTBREAK IN KOREA

2010 to 2011

Livestock Numbers in Korea

Meat Cow 2,940, Milk Cow 404, Pig 8,851 (x1000)

Preventive System KAHI S

Korea Animal Health Integrated System Special Disinfection from November to May Central task force for vulnerable areas

Strengthen general preventive activities

• Animal and Plant Quarantine Agency QIA

Livestock Culture System Upgrade

Strong anti-epidemic system SOPs for each livestock model, field manual · Best practices Disinfection Level for each farm Vehicle Registration with GPS (from August 2012)

I nternational cooperation

Livestock Quarantine Cooperation Office (China, Japan, Korea) Participate actively in OI E activity

Vehicle Tracking with GPS system

QIA: the Animal and Plant Quarantine Agency

Animal and Plant Quarantine; Control and Prevention of Animal and Plant Pests and Diseases; and Research and Development of Veterinary Science and Plant Quarantine Technology. Implement disease control and prevention measures proactively to lay the foundation to become a country free of major animal diseases, including FMD and HPAI; strengthen the surveillance and rapid response system for exotic pests and diseases Establish a preventive border quarantine management system to improve productivity and ensure stringent quarantine measures; secure the safety of animals and livestock products preemptively by strengthening risk assessment to actively respond to changes in quarantine conditions Create a better environment with increased support to boost agricultural exports by providing one-stop support for promising export items; Improve quality control of veterinary medicinal products to promote exports and industrial development; enhance animal protection and welfare and encourage public participation in the field Establish a "smart R&D" system to realize the creative economy; pursue field-

• riented R&D projects to

develop new growth engines and maximize synergy through internal and external collaborative researches; seek to secure convergence technologies

Biosecurity – Strategies at different levels

Strategies for the prevention of the epidemics in livestock at National Level Community Level and Farm Level

Biosecurity at National Level

• Legislation – Law, regulation, etc.
• Quarantine at national border
• Surveillance on epidemics with high risk

KAHIS Surveillance on FMD, HPAI at all times Vehicle Registration and Monitoring

• Collection of International info on outbreaks
• Education of regional officers

Biosecurity at Community Level

• Regional Quarantine/control of movements

human, animal, vehicles

• Regional disinfection
• Regional surveillance
• Education of farmers/workers

disinfection methods disease control

Biosecurity at Farm Level

• Quarantine
• prevention of pathogens entry
• Disinfection
• regularly inside and outside
• Prevention
• removal of pathogens

Pathogen Entering Points

Food, Drinking water, Bedding, Owners, Workers, Visitors, Transport Vehicles, Animals, Wildlife, Insects, Aerosol, etc

Entry Control

People: a major cause of transmission Farm workers, Suppliers, Any other visitors Fences and Walls

Deliveries in and out

The Rules:

transfer at the gate or entrance if possible

• Livestock dispatch :

full vehicle disinfection before pick up

• Waste :

disposal and removal at gate only

• Carcass and waste storage :

burn or transfer off farm at the gate only

• Feed deliveries :

transfer onto a farm vehicle at the gate only

Feed – Check points at Farm Quality of feed suppliers Farm storage conditions Processed food if possible Delivery control at gate Regular cleaning and disinfection of feed container

NEAR FUTURE PROSPECTS

Bio Security Service S ystem

Livestock disease control with rapid diagnosis and prevention Bio Security Service System with the initiative of private sector

General

Period: 2011.07.11 – 2014.04.30 Active Participants: Kyungbuk, Chungnam, Kangwon, Seoul, Wonju, Chunchun Principal: GIB with 23 companies and 21 institutes
