On 1st June 2011, in the central part of Lithuania, in the village of Šils, during an investigation in the pig farm of the joint-stock company “Beržs kompleksas”, an outbreak of classical swine fever (CSF) was confirmed by the National Food and Veterinary Risk Assessment Institute (NFVRAI), which is the designated National Reference Laboratory for CSF of Lithuania.
Out of 63 samples tested, 36 were found positive for antibodies against CSF, 13 were doubtful and 14 were negative. All the samples were analyzed by RT-PCR and three samples were found positive. Further investigation is continuing by virus isolation and virus neutralization. Genotyping of the virus is being performed. The positive samples are being sent to the EU Reference Laboratory for further analysis.
All the CSF eradication and prevention measures have been applied in the outbreak and around it in accordance with the provisions of Council Directive 2001/89/EC of 23 October 2001 on measures for the control of classical swine fever. Clinical examination and all sampling and testing procedures are carried out according to Commission Decision 2002/106/EC of 1 February 2002 approving a Diagnostic Manual establishing diagnostic procedures, sampling methods and criteria for evaluation of the laboratory tests for the confirmation of classical swine fever.
A standstill regime for pigs is introduced in the whole territory of Lithuania for trade and export.
No movement, no trade (in or out) of pigs from the infected farm was done to EU countries.
On all the industrial pig farms of Lithuania which export live pigs, trade in pigs with other EU Member States and move pigs within the country, clinical and laboratory examination starts to be performed.
State Food and Veterinary Services start the investigation of the outbreak and all the measures.
