1. PM 330 Biosecurity Biosecurity = safety of living things To the poultry industry…. protecting poultry flocks from any type of infectious agent - viral, bacterial, fungal, or parasitic

2. Biosecurity – Needs of poultry producers -Original poultry farms were small in size and bird # 100s to 1000s of birds Dr.Birkett Howarth, UGA Fro m Dr.Birkett Howarth, UGA

3. Biosecurity – Needs of poultry producers -Now, vertical integration → → very large farms high bird #’s 100,000s of birds! From Dr.Birkett Howarth, UGA

5. 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

6. Biosecurity – Preventing disease in poultry -Mechanisms to control disease - Control human traffic - Control pests (rodents, CATS) - Control insects - Control plant growth near bldgs Agent Environment Host

7. Biosecurity – Preventing disease in poultry -Controlling human traffic 1.Good records of access to bldgs Poultry diseaseSurvival time away from host Mycoplasma< 1 d Coryza virus1-3 d Influenza~ 1 wk Newcastle~ 1 wk Fowl cholera1-3 wks Mareks disease1-3 wks Bursal disease1-3 mo. Avian TBYears!

8. 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

10. Biosecurity – Preventing disease in poultry -Controlling human traffic 4. Control vehicle movement ALWAYS clean to dirty NEVER backwards 5. Keep vehicles clean Sanitize upon facility entry & exit http://www.ryko.com/adweb/R168Main.jpghttp://www.ryko.com/adweb/R168Main.jpg9/04

11. Biosecurity – Preventing disease in poultry -Controlling bird disease 1. Vaccinations - choose appropriate vaccine - choose appropriate administration - be aware of risks! http://www.zealindia.com/gifs/header-chick-vaccine1.jpghttp://www.zealindia.com/gifs/header-chick-vaccine1.jpg 9/04 2. Flock profiling - routine serology and necropsy

12. Biosecurity – Preventing disease in poultry -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

Report suspected disease outbreaks - companion, production or wild birds http://www.health.co.hernando.fl.us/WestNileVirus/dbsurv082302.jpghttp://www.health.co.hernando.fl.us/WestNileVirus/dbsurv082302.jpg 9/04

14. 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

15. 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) http://www.aphis.usda.gov/lpa/issues/enc/newcastle012103b.gifhttp://www.aphis.usda.gov/lpa/issues/enc/newcastle012103b.gif 9/04
