1. Livestock Diseases 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
FMD (Foot and Mouse Disease) Virus 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
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)

Livestock Disease CONTROL SYSTEMS
Livestock Disease Control Strategy 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 GPS Registration system for Livestock Transporting Vehicles *******
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- oriented 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
Bio Security Service S ystem NEAR FUTURE PROSPECTS
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
System Description 33
Benefits expected 1. Activation of Related Industries 2. Decrease in the Damage due to the outbreak 3. Increase in employments, sales and investments
