CFIA Avian Influenza Initiatives

• Reportable Disease Response– Priority

• Protect animal health, human health, economy.

– 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
