Alberta Veterinary Surveillance Network Effective and progressive network of veterinary food animal

1
Alberta Veterinary Surveillance NetworkEffective
and progressive network of veterinary food animal
practices that will serve as the foundation for
animal health surveillance in Alberta

• John Berezowski
• Food Safety Division
• Alberta Agriculture Food and Rural Development

2
Key Results

• A strategic system to collect real time data and
  disseminate animal health information on an
  ongoing and timely basis.
• (for the mutual benefit of veterinarians,
  industry, government)
• Access to Alberta livestock and poultry for
  targeted surveillance, research and food safety
  programs.
• Document a valid veterinary infrastructure in
  Alberta

3
Objectives

• Detect emerging (/- foreign) diseases
• Estimate herd prevalence of diseases
• Zoonotic, food safety, market access
• Important to veterinarians, industry, public
• Establish freedom from disease
• Important for trade
• Monitor disease trends
• Spatial and/or temporal
• Impact of control programs
• Relationship with AVMA/practitioners
• Essential for animal health surveillance

4
Unique Attributes

• AVSN will provide something that no other
  surveillance effort in Alberta Agriculture has
• Real or Near-Real time
• Systematic collection and analysis of data from
  several varied surveillance sources for
• Identification and investigation/response to
  important livestock health events
• And
• Production and communication of
  information/knowledge about the health and
  disease status of Alberta livestock and poultry
• Emphasis Integrated real-rime approach to data
  analysis, event detection and information
  production and reporting

5
Definition of surveillance

• Ongoing, systematic and adaptable collection,
  analysis, interpretation and dissemination of
  data about health, diseases and their
  determinants in a population with the purpose of
  responding to changes in the populations health
  or disease status

6
Definition of surveillance

• Ongoing, systematic and adaptable collection,
  analysis, interpretation and dissemination of
  data about health, diseases and their
  determinants in a population with the purpose of
  responding to changes in the populations health
  or disease status
• Dz/event identification
• Response
• Communication

7
Identification

• Data collection/monitoring surveillance
• Event detection and/or data collection for
  reports
• Continuous
• Syndromic, Dx labs, practitioners
• Single and/or repeated
• Surveys, questionnaires, research
• No data collection surveillance
• Reportable disease programs
• Meat inspection

8
Response

• Investigate
• Gather more data/information
• Drill down
• On farm disease investigations
• Dx tests, Dx pathology etc
• Control/eradication procedures
• Quarantine, stamping out etc

9
Communication

• Notification
• Notify the responding agency/group
• Suspect reportable dz
• Reporting
• Produce information/knowledge from the data
• Disseminate to stakeholders

10
AVSN - Identification

• Data collection surveillance
• Continuous (near-real time event detection)
• Veterinary Practice Surveillance (VPS)
• Targeted and non-targeted surveillance
• BSE surveillance (CABSEP) (text mining/AI)
• Diagnostic laboratories (text mining/AI)
• (Livestock movements?)
• Single and/or repeated
• Targeted surveillance, surveys, questionnaires,
  research
• Outbreak/event investigation
• Integrated approach
• Combine data from many sources
• Detect events, produce information/knowledge

11
AVSN - Identification

• Non data collection surveillance
• Chief Provincial Vet (CPV), AB Practitioners,
  Others
• Suspect emerging or reportable
• Meat inspection in provincial plants
• Unusual inspections

12
ASVN - Response

• Investigate
• Gather more data/information
• Drill down
• On farm disease investigations
• Livestock Disease Investigation Network (LDIN)

• Resolve the Dz problem
• Within AAFRD Mandate
• Assist industry/producer/practitioner with
  control/ eradication/mitigation
• Outside AAFRD mandate
• Industry, WCVM, U of C, others

13
AVSN - Communication

• Notification

• Other screening tests serology, culture and
  sensitivity
• Easy to modify driven by VPS web page

41
Neuro/rec undifferentiated

• Total number 70
• Diagnostic tests 0
• BSE tested 57
• BSE neg, but why did they die?
• Candidates for targeted surveillance
