CFIA Avian Influenza Initiatives
• Reportable Disease Response– Priority
• Protect animal health, human health, economy.
– Dedicated Resources• National AI Working Group
– Federal: AAFC, CBSA, PHAC, HC, EC– Provincial: MOE, BCMAL, Health Authorities, CDC– Industry, Public
– Local Initiatives (BC)
CFIA Avian Influenza Initiatives
– Multifaceted • Prevention
– Policy/procedures– Biosecurity– Surveillance
• Control and Eradication– Destruction– Disposal
• Recovery– Compensation
PreventionPrevious Response to AI
• Only Highly Pathogenic AI – H5 and H7– Inoculation of chicks causing >75% mortality– Intravenous Pathogenicity Index > 1.2– Cleavage site analysis of hemagglutinin
protein has multiple basic AA.
PreventionCurrent Response to AI
• Any H5 or H7 AI virus – Low or High Pathogenic strains
• Any AI A virus causing serious mortality (as per IVPI or ICPI)
• Resulted from low path strains to high path mutations.
Prevention: Biosecurity
Prevention
• Biosecurity– National Office of Biosecurity
• Capital Region
– National Specialty Bird Pilot Projects• Assess specific animal husbandry issues
– Squab, waterfowl etc.
• Analyse and Develop effective procedures• Implementation• Audit/ Verification
Prevention
• Surveillance– Early Detection– Active and Passive– CFIA Serologic survey for H5 and H7– Compartmental Approach– Primary Breeders, Multipliers, Production
Classes
Control and Eradication
Destruction (Euthanasia)
Control and Eradication
• Humane Destruction– Alternate methods to deal with various
species and situations• Modified Atmospheric Chambers• Gas Mixtures and Delivery
– Surge Capacity
Control and Eradication
• Disposal
• Mass Disposal Options– Infected, Non Infected– Various commodities
• National Protocols and Procedures
• Provincial and Site Specific Issues
Disposal
Disposal
Disposal
Recovery
• Compensation– Review of Health of Animals Act and
Regulations– Method of calculating values– Maximum values
• Vaccination– Vaccines, protocols
