The last recorded outbreak in Campania was in April 2012.

On 10 May 2013: request to the European Commission in order
to recognize Campania Region as free from SVD and to remove
it from Annex II of Decision 2005/779/EC (Regions not free
for SVD)

The European Commission required an additional plan of
control in back-yard farms. The results of this plan are being
processed and will be sent shortly to the Commission.

2014 SVD outbreaks in Potenza province
(Basilicata region)

1 primary outbreak and 1 secondary outbreak
SVD outbreaks 2014

At the end of 2013 a serological positivity has been detected in the
breeding farm (code 096PZ030). No clinical signs. Virological tests were
negative. In the farm were kept 1650 pigs.
According to the SVD national program the animal were destined to
slaughterhouse and meat was handled according to EU legislation
(national market only, special mark).
The animals were sent to the slaughterhouse by channeling procedure and
a time program for slaughtering was scheduled by competent authority.
At the end of that program (22/04/2014) a pig of the last lot (4 pigs)
showed a clinical sign (presence of vesicles on the mouth)
On 24.04.2014 the National reference laboratory confirmed the primary
outbreak.
SVD outbreaks 2014

The secondary outbreak was confirmed (by
serological test + epidemiological connection with
the confirmed outbreak) on 30.04.2014 in a
fattening farm cod. 059PZ753 with 686 pigs, that
introduced pigs from breeding farm 096PZ030 (the
two farms involved belong to the same owner).

All 690 pigs have been killed and destroyed and
cleaning and disinfection in both outbreaks were
carried out.
Control measures adopted
In the Province involved:

SVD Outbreaks and restriction zones:
Measures established in Council Directive 92/119/EEC and
Commission Directive 2007/10/CE are applied
Movement standstill also in the remaining part of the Province.
SVD free status of Potenza province has been withdrawn
(Commission Decision 2005/779/CE).
All the farms of the Potenza province have to be serologically
tested, 2 times, 28 – 40 days apart (P: 5%, I.C: 95%) to regain the
status of a Region free from MVS.
Results

All lots moved from the breeding farm cod.
096PZ030 (the origin of infection) have been
traced and submitted to serological tests. Most of
them were directed towards the fattening farm cod.
059PZ753 of the same owner (secondary outbreak).
Few lots were destined to back-yard farms. No
further secondary SVD outbreaks were detected.
Conclusion
To
date, a possible hypothesis for the introduction of
infection in the farm 096PZ030 is the contamination of
truck during animal trade. In particular, the same vehicle was
used both for the transportation of animals to fattening farm
059PZ753 and for the delivery of pigs to back-yard farms.
Moreover the owner used a product not appropriate for the
disinfection of vehicles with regard the SVD virus.
Surveillance
activities are ongoing and all 2,079 tests carried
out by the veterinary services at the moment in the farms
located in the Potenza province are negative.
Thank you for
attention
