Biosecurity

Protection from exposure todisease

What? Why?

How?


3/43

Biosecurity

A set of management practices whichwhen followed correctly reduce thepotential for the introduction andspread of disease causing organismsonto, and between sites.

q From the perspective of the birdrather than just the farm


4/43

Biosecurity

Three Key Levels of Biosecurity

q Conceptual Biosecurity

q Structural Biosecurity

qOperational Biosecurity


5/43

Biosecurity

Conceptual Biosecurity

q Involves Site planning

q Location e.g proximity to otherfarms, transport etc.

q Almost impossible to change once

committed without very high cost


6/43

Biosecurity

Structural Biosecurity

q Concerns the design of the farm and

buildings.

q Includes house design (easy to

clean), site layout and security.

q Expensive to change once built.


7/43

Biosecurity

Operational Biosecurity

qThe points involved with day to day

running of the site.q Includes routine disinfection, control

of visitors, source of stock etc.

q

Can be modified at low costaccording to requirements


8/43

Disease transmission

qDifferent disease causing agentsrequire differing priorities in relationto biosecurity

qThere is a direct relationshipbetween where the agent multipliesin the bird and its mode of

transmission from one bird toanother, or from one site to another


9/43

Disease transmission:Respiratory diseases

q high concentrations in therespiratory tract

q+++ mucus

q sneezing and coughingq aerosols

q e.g. ND, IB, AI, TRT, mycoplasma


10/43

Disease transmission:Enteric (gut) diseases

qDiarrhoea

q spread via droppings

q e.g. salmonella, campylobacter,coccidiosis, viruses


11/43

Disease transmission:Vertical transmission

q from breeders

q infection via air sac or oviduct

q egg contamination

q egg transmission

q e.g. mycoplasma, salmonella


12/43

Disease transmission:Site contamination

q persistent, resistant organisms

q contaminate litter, equipment,

environment

q e.g. ILT, Gumboro, Mareks, CAV,

many bacteria

14/43

Biosecurity - why?

1. To keep lethal, highly contagiousdiseases out of premises e.g.Newcastle disease (Fowl Pest), avianinfluenza, or acute Gumboro disease

2. To reduce challenge by commonpathogens known to reduceproductivity such as E.coli and

coccidiosis


15/43

Biosecurity - why?

3. To reduce or eliminate, backgroundimmunosuppressive agents such asMareks disease, chicken anaemia orGumboro disease, which leave birdssusceptible to other diseaseorganisms

4. To reduce contamination with

agents of public health significance,such as salmonella or campylobacter


16/43

Methods of spread

1. Vermin e.g. salmonella, pasteurella

2. Feed e.g. salmonella, some NDstrains

3. Wild birds e.g. mycoplasmas, ND,avian influenza, ?IB, ?TRT, bacteria,worms


17/43

Methods of spread

4. Water e.g. E. coli, salmonella,campylobacter

5. Hatchery e.g. salmonella,

aspergillus, enterococcus,pseudomonas, mycoplasmas

6. Windborne e.g. IB, ND, TRT, ?mycoplasmas

7. Faecal e.g. Gumboro, ND,salmonella, mycoplasma, viruses


18/43

Control Areas -Inanimate

1. locate away from other poultry (>5miles)

2. avoid waterways, ponds or lakes

3. avoid putting birds on range4. avoid major roads

5. remove litter from farm

6. concrete around houses7. avoid standing water

8. use potable drinking water with lowTVC


19/43

Control areas - People

q limit staff movements

q avoid visitors

q control site traffic

q spray vehicles

q adequate protective clothing

q BOOTS

q hand washingq ?showers


20/43

Control areas - poultry

qObtain stock from high health statussources.

q Carry out regular health monitoring

and auditsq Carry out daily and proper disposal

of deaths / culls.


21/43

Control areas - sitedecontamination

qEffective cleaning anddisinfection

q

adequate turnaround timeqinclude houses, aprons,equipment

quse a closed water systemqcarry out water sanitisation


22/43

Control areas - sitedecontamination

qUse a total feed system

qcarry out regular vermin

controlqaudit efficacy

quse only products with

proven broad spectrumefficacy
