After the detection of suspected cases of FMD in Jinan, Shandong province, and Xinyi, Jiangsu province, the local veterinary administrative departments promptly implemented blockades within a 3-km radius around the infected areas. Prevention and control measures taken in the infected areas included blockade, stamping out and disinfection. Emergency vaccination was implemented on the susceptible animals in the areas at risk.
Serological surveillance by NSP-3ABC-ELISA(1) was conducted on all susceptible animals in the affected areas and the areas at risk. By the end of blockades, no FMD virus type Asia 1 was detected, and quarantine was lifted.

FOLLOW-UP REPORT NO. 3 (FINAL REPORT- CONTINUATION)See also: 23 November 2006, 2 March 2006, 16 February 2006, 19 January 2006, 19 January 2006, 30 December 2005, 23 December 2005
Information received on 12 June 2006 from Dr Leif Denneberg, Chief Veterinary Officer, Swedish Board of Agriculture, Jönköping:
End of previous report period: 15 February 2006 (see Disease Information, 19 [9], 157, dated 2 March 2006).
End of this report period: 12 June 2006.
Following eradication of the outbreaks of Newcastle disease (ND) in Östergötland and Skåne in 2005 and in accordance with the relevant OIE guidelines, Sweden is again to be regarded as free from Newcastle disease.
For many years, Sweden has applied a strict, non-vaccination and stamping-out policy as regards ND and has only experienced a few outbreaks of this disease during the past years.
However, on 15 December 2005, Sweden received confirmation from the European Community Reference Laboratory (CRL) in Weybridge (United Kingdom) of the presence of ND virus (intracerebral pathogenicity index: 1.275) in a sample collected in a Swedish holding of layer hens. The holding was situated in the county of Östergötland (in central Sweden on the east coast). The same virus was identified by PCR(1) (no virus found) in one additional farm, situated approximately 500 m from the first outbreak.
On 28 December 2005, a second suspicion, in another laying hen farm situated in the county of Skåne approximately 300 km away from the primary case, was confirmed by the CRL.
Following the suspicion and the confirmation of ND, all measures according to EC legislation (Council Directive 92/66/EEC) were applied. Information was sent to all European Union Member States and to the OIE.
Already on suspicion, on 22 November 2005 (when antibody titres against paramyxovirus type 1 were detected), stamping out was applied to the poultry at the first affected farm (Östergötland), with destruction by rendering. Preliminary cleaning and disinfection were finished on 25 November 2005.
Stamping out, with destruction by rendering, was applied to the second infected farm (in Skåne) on 12 December 2005. Preliminary cleaning and disinfection were finished on 15 December 2005.
Epidemiological and inventory investigations were carried out. Within the protection and surveillance zones, commercial farms were clinically inspected and found to be healthy. All hobby flocks identified within the 10-km-radius zones were contacted and informed.
Following the confirmation of ND on 15 and 28 December 2005, all additional measures required by EC legislation, including transport restrictions for live poultry, hatching eggs, fresh poultry meat, eggs for consumption and litter/manure from poultry within the 10-km-radius zones around the outbreaks, were immediately applied.
In accordance with Directive 92/66/EEC, taking into account all the measures taken and that there was no suspicion of further spread of the disease, the transport restriction zones (10 km around the outbreaks) were lifted on 16 January 2006.
The source of infection for the cases is still unknown but suspected to have been wild birds.
In order to control the outbreak as soon as possible and to stop any further spread of the disease, Sweden already on suspicion took even more stringent measures than those laid down in the relevant EC legislation. Based on the epidemiological investigations conducted, there was no reason to believe that the virus spread outside the affected holdings.
All restrictions have been lifted and, as from 12 June 2006, Sweden is again to be considered free from ND(2).
It should be noted that vaccination of poultry against ND is prohibited in Sweden. Moreover, Sweden has a nationwide surveillance programme, in which all breeding poultry flocks are sampled for infectious diseases including ND. Any suspicion of ND must immediately be notified to the Veterinary Authorities.
(1) PCR: polymerase chain reaction
(2) Under the terms of Article 2.7.13.2. of the OIE Terrestrial Animal Health Code, a country in which a stamping-out policy is practised may be considered Newcastle disease free six months after the culling of the last affected animal.

Eight outbreaks of classical swine fever (CSF) had been officially recorded from 3 March 2006 to 9 May 2006 in North Rhine-Westphalia land: 5 outbreaks were detected in the district of Recklinghausen (the last on 1 April 2006) and 3 outbreaks were detected in the district of Borken (on 1 April 2006, 5 May 2006 and 9 May 2006, respectively). All CSF cases were caused by CSF virus type 2.3 Güstrow.
The German veterinary authorities applied a stamping out policy. In addition, all pig herds in the established protection zones and, furthermore, all other herds that were identified as dangerous contacts were culled.
No more CSF cases have occurred since 9 May 2006 and all samples from the areas concerned have tested negative so far.
Movement restrictions are still being applied for the time being subject to further testing of herds in the affected area.
