Processes, protocols, management practices, and standard operating procedures

Keeps disease agents outContains, prevents disease spreadMeasures conducted

Scope of ProceduresSlide7

Identify levels – imagined or physical

Clean areas (non-infected, protected)Dirty areas (potential source of

infection)

Line of Separation, C&D Line, Perimeter Buffer Area

Marked on map and by physical cuesImplemented at farm or barn levelCritical control/controlled access point

FAD PReP/NAHEMS Guidelines: Biosecurity - OpMeasures

Separate Clean and DirtySlide8

Evaluation to determine procedures

Critical control pointsApply control (to prevent harm)At entrances and/or exits to premises, facility, or barn

unit

Apply strategic measures

C&D, movement controls, and employment restrictions

Critical Control PointsSlide9

Assigned responsible individual

Develop written site-specific planImplement and train othersPrevent transfer of disease on clothes and personal articles Biosecurity attire, shower in/shower out

Wildlife,

insects, and household petsClean spilled feed immediatelyStructural controls to prevent entryFollow up with control programs

Reduce wildlife habitat

by

mowing

VectorsSlide13

Dedicated equipment - avoid sharing

Cleaning protocols Between groups on the premisesPrior to crossing Line of SeparationSupply and delivery entrance protocols to eliminate contamination

USDA APHIS and CFSPH

FAD PReP/NAHEMS Guidelines: Biosecurity - OpMeasures

EquipmentSlide14

Internal vehicles service the facility

External vehicles excluded Thorough C&D for those that must enter protected areaWheels and wheel wellsAnimal cargo areas and between loads

Deliveries at a distant location

Avoid crossing work paths

FAD PReP/NAHEMS Guidelines: Biosecurity - OpMeasures

VehiclesSlide15

Processes that prevent

cross-contaminationOff-site carcasses, feed deliveryOther work paths

Prevents

attraction of

wildlife/vectorsStorage, composting, pick up at a distance from live animalsRendering trucks do not enter protected space or Perimeter Buffer Area

USDA APHIS and CFSPH

FAD PReP/NAHEMS Guidelines: Biosecurity - OpMeasures

Carcass DisposalSlide16

Removal process prevents exposure to live animals

Management and handling avoids cross-contamination of feed delivery and work pathways

USDA APHIS and CFSPH

FAD PReP/NAHEMS Guidelines: Biosecurity - OpMeasures

Manure/Litter ManagementSlide17

Quarantined animals/herds usually do not move off the premises

Maintain as a closed herdReplacements from infection-free sourcesTransported in cleaned carriersIsolation of new additions

USDA APHIS and CFSPH

FAD PReP/NAHEMS Guidelines: Biosecurity - OpMeasures

AnimalsSlide18

All-in/all-out management of groups

No re-entry without biosecurity measures, especially at load-outNo re-entry of animals once they leaveSpecific order of daily careSegregation of sick animals

Reduce environmental contamination

Routine regular cleaningThorough cleaning and downtime between groupsRegular maintenance of the outside environment to discourage vectors

MaintenanceSlide21

Secure animal areas

Prevents breaches in biosecurityPrevents unauthorized accessPrevents lack of vigilance after-hoursLock buildings when no one present

No circumventing biosecurity rules
