Slide Content

Biosecurity Overview Adapted from the FAD PReP /NAHEMS Guidelines: Biosecurity (2016)

Basic biosecurity concepts Routes of exposure Steps to develop a biosecurity plan Three levels of biosecurity Practical application of operational measures in bioexclusion and biocontainment USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview This Presentation

Measures or management practices Prevent spread of disease Protect in routine, daily management Contain disease in an emergency Individual assessment/analysis Health status and species Management and site arrangement Sources of contamination Areas needing protection USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview Biosecurity Concepts

Line of Separation Imagined or physical Pathways for disease movements Onto, off of, and within the facility Critical control points Measures to prevent transfer People, supplies, equipment, vehicles, feed, mortalities, animals Bioexclusion and/or biocontainment USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview Separate Clean and Dirty

Routes of Exposure to Disease USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview

Direct Contact Direct transfer to skin, mucous membranes, wounds Aerosol Inhalation of infectious droplets Oral Ingested, consumed, environmental sources USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview Routes of Exposure

Fomites Inanimate objects Lateral spread Vectors Living organisms Zoonotic Disease Any of the routes Disease-specific USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview Routes of Exposure cont’d

Developing a Biosecurity Plan USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview

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 - Overview Developing a Biosecurity Plan

Movements of animals Closed herd is more protected Additions from offspring within the herd Managed in small, isolated groups All-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 - Overview Developing a Plan cont’d

Levels of Biosecurity USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview

Conceptual Location , geospatial siting, orientation of the facility Structural Capital investment, construction to prevent disease spread Operational Processes, management practices, standard operating procedures to exclude or contain disease USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview Three Levels of Biosecurity

Premises Biosecurity USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview

Responsibility and authority Assesses, designs, implements Monitors and enforces Ensures ongoing effectiveness Certifies compliance Communicates and trains everyone on concepts and procedures USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview Officer, Manager, Coordinator

Line of Separation Prevent pathogens from crossing Point of access = critical control point Biosecurity measure defined for each movement Perimeter Buffer Area Transition with sanitation standard Area of reduced contamination Wider separation between clean and dirty USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview Establish Separation

Fomites Decontamination People Biosecurity attire and sanitation Vectors Barriers or control programs Production traffic patterns Avoid cross contamination USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview Operational Measures

Cleaning and disinfection Reduces, inactivates, or destroys biological pathogens Physical, chemical, or combination Biosecurity attire/PPE Prevents transfer by outerwear Protects responder health if zoonotic USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview C&D and Biosecurity Attire/PPE

Biosecurity in an FAD Response USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview

USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview Zones, Areas, and Premises

Premises designations Source of infection Enhanced risk of disease exposure Type of response activities Biocontainment and/or bioexclusion Guidance on response activities provided by Incident Command USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview Containment and/or Exclusion

Separation between dirty and clean Hot Zone or Exclusion Zone (EZ ) Warm Zone or Contamination Reduction Zone (CRZ ) Cold Zone or Support Zone (SZ ) Access is controlled Decontamination Corridor Critical control point USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview Biocontainment Work Zones

USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview Biocontainment Work Zones

USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview Decontamination Corridor

Dirty operations at quarantined sites Understand all biosecurity protocols Identify Hot, Warm, Cold Zones Define and defend the Line of Separation Park vehicles in Cold Zone Don PPE – disposable is preferred USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview Protocols for Biocontainment

Protect electronics, to be immersed Contain and secure disposables Carry in only essentials All movements through the Decontamination Corridor Minimize unnecessary exposure C&D and doffing in Decon Corridor Tools, equipment, vehicles USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview Protocols for Biocontainment cont’d

Clean operations at non-infected sites Follow premises’ biosecurity plan Identify Line of Separation Animal area is clean, protected side Remove all contamination prior to entry at controlled access point Don biosecurity attire/PPE USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview Protocols for Bioexclusion

Minimize movements and spread Begin activities with most susceptible animal group When exiting across Line of Separation, doff PPE C&D boots and all equipment Secure disposables according to the biosecurity plan USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview Protocols for Bioexclusion cont’d

Biosecurity concepts multifaceted Protect healthy animals from introduction of disease Contain disease from spreading in an outbreak FAD response efforts require both biocontainment and bioexclusion practiced correctly and consistently USDA APHIS and CFSPH FAD PReP/NAHEMS Guidelines: Biosecurity - Overview Conclusion
