Active surveillance - design

  • The responsibility of Evira
  • Annual plan prepared and agreed in the co-
  • peration group for Animal Health in Evira (ETYR)
  • Major changes and new programmes agreed also

with Evira’s management board and MAF

  • Special working teams for the design and follow-

up of EU-reimbursed programmes (AI, BT, rabies, BSE)

Nordic Serology 5th May 2015

Active surveillance - Implementation

  • Sampling requests and directions sent to RSAA’s

(Regional State Administrative Agencies), dairies and slaughterhouses by the AHAW Unit

  • The MVO’s (Municipal Veterinary Officers) are

responsible for carrying out sampling at farm level and RSAA’s supervise

  • National compilation of results and follow-up in Evira
  • Results reported annually in the MANCP report and in

the report of Animal Diseases

Active surveillance in bovines

  • Target population

– Bulk milk samples from dairy herds via dairies, – Blood samples from suckler cow herds via slaughterhouses (10 sera pooled in surveillance) – Bulk milk and blood samples in relation to Artificial insemination from farms and AI-center – Fallen stock, emergency slaughtered and clinical suspicions above the age limits (BSE)

  • Diseases included in the regular surveillance:

– Bluetongue, IBR, EBL, Bovine Viral Diarrhoea, Brucellosis, BSE – several other diseases as required in the EU-legislation in relation to artificial insemination.

Active surveillance in bovines

  • Surveillance on dairy herds: sampled once a year in

Jan-Feb  cross sectional  snapshot of the situation

  • Surveillance of suckler cow herds: sampling at

slaughter all year round

  • Sampling in relation to AI continuous
  • BSE testing continuous

Nordic Serology 5th May 2015

Active surveillance in bovines

  • Slaughterhouse sampling targeted to suckler cow herds since

2003

  • Whole census sampling of dairy herds  towards risk-based

sampling since 2008/2011  random sampling + risk areas (BT and BVD) + herds with abortions + embryo transfer with imported embryos

  • BSE testing according to EU-legislation, since 1.3.2013 no

testing of healthy slaughtered animals of low risk countries

  • Non-notifiable diseases:
  • Q-fever in 2009 (14% of dairy herds  0,2% seropos)
  • SBV of suckler cow herds in 2012 and dairy herds in 2013 and

2014

Other surveillance

  • Pathological autopsies – findings invoking

suspicion or to rule out the diseases

  • Sampling in connection with exports and imports

Additional Information

  • FINAS (Finnish Accreditation Service)

accreditation (T014, standard ISO/IEC 17025, http://www.finas.fi/scope/T014/fi)

  • participation to several proficiency tests annually

(ASF, CSF, FMD, BT, AI, ND, BSE, scrapie, fish viral diseases etc.)

Surveillance in Finland, conclusions etc

  • Demonstration of freedom from the disease, in some

cases detection of disease and/or eradication (i.e. BVD, Maedi-visna, SBV)

  • All surveillance programmes are under evaluation (by

Risk Assessment Unit)

  • Sample sizes and representativeness
  • From whole census surveillance towards Risk-based

surveillance

  • Cost-effectiveness
  • In addition: Can we pool samples for surveillance? If

yes, how many per pool?
