Biosecurity
Biosecurity = safety of living things
To the poultry industry…. protecting poultry flocks
from any type of infectious agent
- viral, bacterial, fungal, or parasitic
Biosecurity – Needs of poultry producers
-Original poultry farms were small in size and bird #
100s to 1000s of birds

Biosecurity – Needs of poultry producers
-Now, vertical integration → → very large farms
high bird #’s
100,000s of birds!

Biosecurity – Preventing disease in poultry
-Sources of disease
-new birds
- carrier w/in flock
- infected eggs
- humans (hands, feet, clothes)
- dust, feathers & manure
- wild birds, rodents, insects
- vaccines (live, contaminated)
- contaminated feed
- water
- air
Biosecurity – Preventing disease in poultry
-Mechanisms to control disease
- Control human traffic
- Control pests (rodents, CATS)
- Control insects
- Control plant growth near bldgs

Biosecurity – Preventing disease in poultry
-Controlling human traffic
1. Good records of access to bldgs

1-3 mo.
Avian TB
Years!
Biosecurity – Preventing disease in poultry
-Controlling human traffic
1. Good records of access to bldgs
2. Control what people are carrying
- shower in/out facility
- coveralls/lab coats
- booties, hairnets, gloves etc….
- footbaths
- wash your hands!!!
3. Keep all doors locked to keep out intruders

1. Vaccinations
- choose appropriate vaccine
- choose appropriate administration
- be aware of risks!
2. Flock profiling
- routine serology and necropsy

-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

-Controlling bird disease
7. Report suspected disease outbreaks
- companion, production or wild birds

Biosecurity – Impact on human health
1. Healthier bird = healthier food product!
Food poisoning linked to parties
Poorly-cooked poultry is a source of food-poisoning
Biosecurity – Impact on human health
2. Healthier bird = more $$$ to producer & consumer!
END cost consumers > $160 million to eradicate
increased poultry prices
21 commercial layer flocks destroyed
(> 3 million birds)
