Biosecurity = safety of living things

To the poultry industry…. protecting poultry flocks

from any type of infectious agent

- viral, bacterial, fungal, or parasitic

slide2

Biosecurity – Needs of poultry producers

Dr.Birkett Howarth, UGA

From

Dr.Birkett Howarth, UGA

  • Original poultry farms were small in size and bird #
    • 100s to 1000s of birds
slide3

Biosecurity – Needs of poultry producers

From

Dr.Birkett Howarth, UGA

  • Now, vertical integration → → very large farms
        • high bird #’s
        • 100,000s of birds!

Biosecurity – Preventing disease in poultry

  • Sources of disease
    • new birds - wild birds, rodents, insects
    • carrier w/in flock - vaccines (live, contaminated)
    • infected eggs - contaminated feed
    • humans (hands, feet, clothes) - water
    • dust, feathers & manure - air
slide6

Biosecurity – Preventing disease in poultry

  • Mechanisms to control disease
    • Control human traffic
    • Control pests (rodents, CATS)
    • Control insects
    • Control plant growth near bldgs

Agent

Host

Environment

slide7

Biosecurity – Preventing disease in poultry

  • Controlling human traffic
  • Good records of access to bldgs
slide8

Biosecurity – Preventing disease in poultry

  • Controlling human traffic
  • Good records of access to bldgs
  • 2. Control what people are carrying

  • Controlling bird disease

3. Cleaning house appropriately between flocks

- downtime helps determine appropriate protocol

4. Proper disposal of dead animals

- quick removal

- incinerate or bag & dispose

5. Reduce stress in house

- stress increases disease susceptibility!

6. Keep ages/species separated

slide13

END cost consumers > $160 million to eradicate

increased poultry prices

21 commercial layer flocks destroyed

(> 3 million birds)
