This PresentationSlide3

Collection of management practices

Prevent introduction/spread of diseaseRoutine and emergency measuresAvert severe, negative impacts of a foreign animal disease (FAD)

Strategic decisions and adequate

investment in management practices

USDA APHIS and CFSPH

FAD PReP/NAHEMS Guidelines: Biosecurity - Concepts

Importance of BiosecuritySlide4

Risk assessment – hazard analysis

Identify sources of potential infectionIdentify areas needing protectionEstablish Line of Separation

Dirty

(contaminated)/clean (protected)

Ascertain site-specific pathways for potential disease movement

Prioritize biosecurity measures

USDA APHIS and CFSPH

FAD PReP/NAHEMS Guidelines: Biosecurity - Concepts

General ConceptsSlide5

Identify critical control points

Any point, step, or procedure to apply control (to prevent harm)Prevent the transfer of a pathogen from entering or leavingInvolve people, supplies, equipment, vehicles, feed, mortalities, animals, and animal products

Bioexclusion and/or biocontainment

USDA APHIS and CFSPH

FAD PReP/NAHEMS Guidelines: Biosecurity - Concepts

General Concepts cont’dSlide6

Routes of Exposure to Disease

USDA APHIS and CFSPH

FAD PReP/NAHEMS Guidelines: Biosecurity - ConceptsSlide7

Direct Contact

Direct transferSkin, mucous membranes, and open wounds

Rubbing

, biting, licking, or contact with body fluids (nose-to-nose)

AerosolInhalationInfectious droplets

USDA APHIS and CFSPH

FAD PReP/NAHEMS Guidelines: Biosecurity - Concepts

Exposure – Direct, AerosolSlide8

Oral

Ingested, consumedLicking, biting, and eating

feed

Environment contaminated

by feces, urine, saliva, and bloodFomitesInanimate objects

Equipment, vehicles, clothing and boots, dust, and feathersLateral spread between facilities as people move

USDA APHIS and CFSPH

FAD PReP/NAHEMS Guidelines: Biosecurity - Concepts

Exposure – Oral, FomitesSlide9

Vectors

Living organismsArthropods, insects, rodents, feral animals, and scavengers Biological and mechanical

Zoonotic Disease

Exposure may occur through any of the routesDisease-specific

USDA APHIS and CFSPH

FAD PReP/NAHEMS Guidelines: Biosecurity - Concepts

Exposure – Vectors, ZoonoticSlide10

Developing a Biosecurity Plan

USDA APHIS and CFSPH

FAD PReP/NAHEMS Guidelines: Biosecurity - ConceptsSlide11

Step 1: Prioritize the disease agents

Consider species/susceptibility, housing, management, wildlife exposure Step 2: Conduct a facility assessment Identify pathways/movements

Step 3: Implement processes to minimize impact of disease

Prevent movements that carry disease

USDA APHIS and CFSPH

FAD PReP/NAHEMS Guidelines: Biosecurity - Concepts

Developing a PlanSlide12

Movements of animals

Closed herd is more protected Additions from offspring within the herdManaged in small, isolated groupsAll-in/all-out

management, less co-mingling

Animals that leave and return create a risk for the herd/flock

Quarantines restrict movements

USDA APHIS and CFSPH

FAD PReP/NAHEMS Guidelines: Biosecurity - Concepts

Developing a Plan cont’dSlide13

Levels of Biosecurity - Preventing

Exposure to DiseaseUSDA APHIS and CFSPH

FAD PReP/NAHEMS Guidelines: Biosecurity - ConceptsSlide14

Producers are responsible

Effective day-to-day proceduresBiosecurity is an investmentProtocols are specificSpecies/mixture of

species

Diseases, susceptibility to disease Intended purpose, economic value

Practicality, facility lay-out

USDA APHIS and CFSPH

FAD PReP/NAHEMS Guidelines: Biosecurity - Concepts

Prevent Exposure to DiseaseSlide15

Farm density

Animal movementTraffic on and off the premisesHuman activityEquipment sharing

Access by wildlife

Housing difficult to cleanMortality disposal near animal housing

USDA APHIS and CFSPH

FAD PReP/NAHEMS Guidelines: Biosecurity - Concepts

Increased Risk of ExposureSlide16

Conceptual

Location, geospatial siting, orientation of the facility

Structural

Capital investment, construction, to prevent disease spread

OperationalProcesses, management practices, standard

operating procedures to exclude or contain disease

USDA APHIS and CFSPH

FAD PReP/NAHEMS Guidelines: Biosecurity - Concepts

Three Levels of BiosecuritySlide17

Facility location

, geospatial siting, orientation, scope, sizeHigher risk Greater farm density, close to wildlife areas, large groups managed as one population

Best

practicesSeparation, isolationSmall

biosecure unitsDistance to wildlife habitats and roads

USDA APHIS and CFSPH

FAD PReP/NAHEMS Guidelines: Biosecurity - Concepts

Conceptual BiosecuritySlide18

Evaluate existing facility

Mitigate/compensate for vulnerabilities:Eliminate (make less attractive) wildlife habitatReroute traffic away from animal areas

Create smaller

biosecure groups

Conceptual Biosecurity cont’dSlide19

Construction, capital investment

Physical design and maintenancePaved parking away from barnsFences, barriers leading to entrances to conduct biosecurity protocols

Locations for cleaning/disinfecting

On-site laundry for outerwearSpecialized anteroom at entry

USDA APHIS and CFSPH

FAD PReP/NAHEMS Guidelines: Biosecurity - Concepts

Structural BiosecuritySlide20

Example of a Danish Entry System

Specialized anteroomPrompts biosecurity protocolsEntering and leavingEnhancements in long term plans

Structural - Danish Entry SystemSlide21

Processes, management practices, standard operating procedures to exclude or contain disease

On-farm movements and managementsPeople, animals, supplies, equipment, vehicles, and other items

Based

on specific risk assessments

Mitigation of conceptual and structural vulnerabilities, and known disease

USDA APHIS and CFSPH

FAD PReP/NAHEMS Guidelines: Biosecurity - Concepts

Operational BiosecuritySlide22

Apply strategic actions at

critical control pointsFocus on inputs and outputsEntrances and exitsWork paths

Processes

Clearly identify separation of clean/dirty
