Definitions

CAPTIVE WILD ANIMALMeans an animal that has a phenotype not significantly affected by human selection but that is captive or otherwise lives under direct human supervision or control, including zoo animals and pets

WILD ANIMALMeans an animal that has a phenotype unaffected by human selection and lives independent of direct human supervision or control

WILDLIFEMeans feral animals, captive wild animals and wild animals

Notifiable in the whole territory, all pigs showing clinical signs suggestive of CSF are subjected to appropriate field or laboratory investigations

Ongoing awareness programme to encourage reporting

General criteria for the determination of the CSF status (1/3) (Article 15.2.2.)

Veterinary Authority has current knowledge and authority over:o Domestic and captive wild pig herdso Wild and feral pigs

Surveillanceo Domestic and captive wild pigso Wild and feral pigs


Domestic and captive wild pig population separated from the wild and feral pig population by appropriate measures, based on the assessed risk of spread within the wild and feral pig population


CSF in wild and feral pigs (Article 15.2.1.)

A Member Country should not impose bans on the trade incommodities of domestic and captive wild pigs in response to anotification of infection with CSFV in wild and feral pigs providedthat Article 15.2.2. is implemented

Article 15.2.2. = risk of transmission from wild and feral pigs to domestic and captive wild pigs mitigated

Surveillance in place for at least 12 months

• No outbreak of CSF in domestic and captive wild pigs during the past 12 months

• No evidence of infection with CSFV in domestic and captive wild pigs during the past 12 months

• No vaccination against CSF carried out in domestic and captive wild pigs during the past 12 months (unless DIVA)

• Imported pigs and pig commodities compliant with the requirements in Articles 15.2.7. to 15.2.14

CSF free country or zone (Article 15.2.3)

Article 1.6.10. of the Terrestrial Code Compliance with the requirements of the Terrestrial Code

Questionnaire specific to apply for aCSF free status

Annual reconfirmation of compliance with Article 15.2.3. CSF free country or zone and reporting of any changes in the epidemiologic situation or other significant events

(Article 15.2.3.)

Maintenance of CSF freedom

Retention on the list requires annual reconfirmation of compliance with Article 15.2.3. CSF free country or zone and reporting of any changes in the epidemiologic situation or other significant events in accordance with Chapter 1.1. of the Terrestrial Code.

OIE Standards for official recognition of CSF freedom

Outline




(Articles 15.2.28. to 15.2.32.)

Surveillance: objective

Domestic and captive wild pigso Demonstrate ongoing freedom

o Detect any introduction of CSFV (early warning)

Wild and feral pigso Demonstrate that CSFV infection is not present in wild and

feral pigs

o If present, estimate the distribution and prevalence of the infection

Surveillance

Prove freedom from CSF (in country/zone) where wild and feral pigs provide a potential reservoir of infection & CSF present in adjacent countries

Free from infection with CSFV Detect the introduction of CSFV

Surveillance in wild and feral pigs

Article 15.2.31. CSFV infection is not present If present, estimate the distribution and prevalence of the

infection Additional challenges…

Clinical surveillance

Virological surveillance

Serological surveillance

Add photos/images

Surveillance: components

Serological surveillance‐ Effective and efficient in unvaccinated populations‐ False positive should be anticipated

Virological surveillance‐ Investigate clinically suspected cases, positive serological

results, increased mortality …

Clinical surveillance‐ Important for early detection‐ But infections might be inapparent

Surveillance: strategy

Randomised samplingOr Targeted, based on:

o The epidemiology of CSF in the regiono Specific risk factors

Swill fed farms Pigs reared outdoors Specific high risk wild and feral pig sub‐populations and their proximity
