INTRODUCTION• What is Biosecurity ?• Controlled diseases vs. the rest• International vs. National vs. Regional vs. Farm

✓ OIE (Office International des Epizooties/ World Organisation for animal health) (http://www.oie.int/en/)

✓ List of controlled diseases (DAFF) (https://www.daff.gov.za/daffweb3/Branches/Agricultural-Production-Health-Food-Safety/Animal-Health/disease-control/list)

PRINCIPLES of BIOSECURITY MITIGATION

1.Prevention of disease introduction

2.Prevention of disease spread

Page 5: BIOSECURITY ON THE GAME FARM: HOW TO STAY CLEAN · •Movement control (multi-species camps, camp location, neighbouring risks) •Stocking density control (intensification - esp.

Prevention of disease introduction• Pre-introduction disease risk assessment (perceived vs. reality) e.g. HW

• Movement control (e.g. MCF, TB, FMD)

• Quarantine Diagnostic services and capabilities• Identification of animals• Trade with reputable producers vs. “Closed herd” principle vs. Speculation• Awareness and control of sources: Veterinarians, Workers (TB status / tapeworms),

Equipment, Feed and Water sources (river vs. borehole)

Prevention of disease spread• Movement control (multi-species camps, camp location, neighbouring risks)• Stocking density control (intensification - esp. contagious diseases)• Test and cull• Cleaning and disinfection (equipment, environment, carcass disposal)

• Vector and reservoir control (e.g. corridor disease in Buffalo vs. theileriosis in Roan)

• Treatment (e.g. wireworm, pasteurellosis etc.)

• Vaccination (NOTE: mostly registered for domestics only)
