5
Disease transmission
  • Animal to Animal
  • Aerosol
  • Fecal/Oral
  • Fomites
  • Zoonotic
  • Vectors

6
Animal to Animal
  • Like humans, animals get diseases from each other
  • Physical contact
  • Sharing food/water sources
  • Sharing medical equipment

7
Aerosol
  • Pseudorabies virus can travel more than 2 mi.
    though air!
  • Germs can float through air and can reach animals
    by
  • Sick animals sneezing, coughing, breathing on
    other animals
  • Ventilation systems

8
Fecal/Oral
Chi Chis contaminated green onions ring a bell?
510 confirmed cases and 3 deaths by November 6,
2003!!!
9
Fomites
  • Inanimate objects on which diseases can live
  • Example- Your animal has a cold and coughs on
    your pencil
  • The germs from your animal are now on the pencil
  • Do you still want to chew on your pencil?

10
Zoonotic
  • Diseases that can be passed from animal to human
  • Examples-
  • Rabies
  • Club lamb fungus
  • Ringworm
  • Monkey pox
  • BSE????

11
Vectors
  • Infected animal Vector
    Healthy animal

12
3 aspects of Animal Biosecurity
  • Traffic Control
  • Sanitation
  • Isolation

13
Traffic Control
  • Minimize who comes on and off farm
  • Delivery trucks
  • Milk haulers
  • Wild animals
  • OR who comes into contact with animals
  • Neighbors
  • Protective clothing

14
Sanitation
  • Keep it clean!
  • Animal stalls should be cleaned
  • Vaccinate livestock
  • Personal hygiene- washing hands!
  • Avoid handling sick animals
  • Wear protective clothing

15
Isolation
  • This is the opposite of isolation!

16
Isolation
  • Keep new or show animals
  • In an area totally separate from other animals
  • A month is best
  • To make sure new/show animal is not carrying a
    disease

17
Why care about Animal Biosecurity?
  • Impact on human health
  • Impact on animal health
  • Economics

18
Human Health
  • Safe food supply needed for healthy population
  • Food supply an easy target
  • Not many people can produce own food if US food
    supply compromised

19
Animal Health
  • Sick animalslow production
  • Mass death

20
Economics
  • No meat/milk/cheese/eggs to sell means no profits
  • Illnessfear ex.- BSE and importation of beef
    stopped
  • Who HAS safe food can charge a bundle for it-
    organic or grass fed beef can 6.00/lb
