  9. Situation in Sardinia and the extraordinary plan for ASF History ASFV genotype I ASF outbreaksnotified in Sardinia 1978 -2011

  10. Situation in Sardinia and the extraordinary plan for ASF Cultural and zootechnical background

  11. Situation in Sardinia and the extraordinary plan for ASF Turning point Last epidemic wave New eradication plan

  12. Situation in Sardinia and the extraordinary plan for ASF Turning point • Creation of “Unità di Progetto (UdP)” for ASF eradication; • Measures to improve the efficacy and efficiency of veterinary service • Culling actions to reduce the illegal free ranging pigs population; • Surveillance plan in domestic pig farms based on risk analysis; • Specific regional plan to verify the efficacy of official controls; • Implementation of individual pig breeding register; • Deep revision of hunting rules and wild boar population management; • Relevant “social” measures. DOMESTIC PIGS 14 034 holdings 178 000 heads WILD BOAR ≈90 000 heads ILLEGAL FREE-RANGING PIGS Thousands

  13. Official controls include: - clinical visit; - compliance with the I&R obligations; - compliance with the rules on animal welfare; - biosecurity requirements; - expected reproductive parameters;- disposal of by-products of porcine origin; - sampling for ASF. a) Holding controlled for ASF: the overall outcome has been unfavourable but the holding results compliant with the clinical and serological parameters.b) Holding certified for ASF: the outcome of the check was favorable for all the parameters considered. Situation in Sardinia and the extraordinary plan for ASF Domestic pigs

  14. Situation in Sardinia and the extraordinary plan for ASF Domestic pigs New cathegorisation of the pig holdings: -Reproduction open cycle: 157 -Reproduction close cycle: 14117 -Backyard: 264 -Fattening: 44 UdP Second Provision Individual identification and registration of breeding pigs Dir. 2008/71/CE registration of pig holdings identification of pig batches Hundreds of new pig farms are registered in the BDN in particular in high risk area for ASF

  15. Situation in Sardinia and the extraordinary plan for ASF Wild boar Active surveillance Strong decrease both of ASFV+ and sero+ Passive surveillance Strong decrease of ASFV+

  16. Situation in Sardinia and the extraordinary plan for ASF Wild boar

  17. Situation in Sardinia and the extraordinary plan for ASF Free ranging pigs

  18. Situation in Sardinia and the extraordinary plan for ASF Free ranging pigs VS Wild boar These results of the risk analysis indicate that the risk to observe one or more ASF outbreaks in domestic pigs holdings in the area in question increases: •5 times if free range pigs live in the area; about 2 times more when free range pigs cohabit with ASF+ wild boars. In areas where free range pigs are not present, this risk increases: •with 20% when in the previous hunting season a ASFV+ wild boars had been found •with 15% when in the previous hunting season a sero+ wild boars had been found; about 2% more if in the previous hunting season a young (< 18 months) ASFV+ or sero+ wild boars had been found. The risk to domestic pigs posed by free range pigs seems much higher than the risk posed by ASF+ wild boars alone.

  19. Situation in Sardinia and the extraordinary plan for ASF Free ranging pigs VS wild boars • Massive depopulation of free range pigs led to an improvement in the ASF situation in domestic pigs and wild boar: • - Domestic pigs outbreaks decresed with 29%; • - Wild boar seroprevalence decresed with 45%; • Wild boar virus prevalence decresed with 14.5%. • All these data could confirm the hypotesis that in sardinia the free range pigs play a much more important role than the wild boar population and could explain the very positive impact of their depopulation in the epidemiological situation

  21. Situation in Sardinia and the extraordinary plan for ASF Controls in the restaurants, agritourisms and banquetts

  22. National surveillance plan for 2020 2. Numerical control of the wild boar population: manage numerical and spatial reduction through a coordinated action, which shall take account of the hunting activity, the controls required by the legislation in force and the actions programmable in the network of Protected Areas 1. Passive surveillance in wild boar populations: (early detection). Notification and diagnostic checks of all wild boars found dead (including those killed in car accidents) and all suspected cases (e.g. increased mortality, symptoms of swine fever).

  23. National surveillance plan for 2020 3. Passive surveillance in pig farms: by law each suspected case shall be immediately reported to the local veterinary service. 4. Verification of the level of implementation of biosecurity measures: non-commercial or backyard farms; commercial farms (breeding farms and fattening farms); farms with free-ranging or semi-free-ranging pigs: pigs are kept outdoors temporarily or permanently.

  24. National surveillance plan for 2020 • e. Training and information campaign for stakeholders: • interministerial cooperation (Ministry of Health, Ministry of Agriculture and Ministry of the Interior), and full involvement of Regions and Autonomous Provinces; • creation and distribution of information material on the risk of introduction and spread of ASF; • training courses to improve the skills of all possible stakeholders of the Veterinary Service: hunters, police, forest guards.

  26. Conclusions • The strategy adopted and the actions undertaken in the last years have been very effective, leading to an unprecedented, favorable situation • All the main risk factors regulating the virus spread in domestic pig are currently under control; • The incidence of outbreaks in domestic pig farms has been drastically reduced; • The surveillance activities have demonstrated the capacity to prevent the spread of the infection in some areas of Sardinia and consequently in the rest of Italy and Europe; • The ASF prevalence in the wild boar population shows clear signs of decreasing and in the very near future the infection zone could be revised and reduced; • The illegal presence of free range pigs in public territories is deeply reduced after a strong action carried out by the regional authorities and risk posed by the free-rage pigs decreased of at least 90%. • The mind of population is now changing after a large awareness campaign; • The political lines and strategies carried on by the last regional government were also recently confirmed by the current leaders; • ASF self extinguishing in the WB in several part of the infected zone; • Risk posed by the free-rage pigs decreased of at least 90%.

  27. Sardinia is not only ASF but also culture, tradition, excellent food and beautiful beaches. Thankyou
