Information received on 21 July 2006 from Dr Hirofumi Kugita, Chief Veterinary Officer, Ministry of Agriculture, Forestry and Fisheries, Tokyo:
End of previous report period: 12 January 2006 (see Disease Information, 19 [3], 31, dated 19 January 2006).
End of this report period: 21 July 2006.
Precise identification of agent: low pathogenic avian influenza virus subtype H5N2.
Date of first confirmation of the event: 26 June 2005.
Date of start of the event: 24 June 2005.
All the control measures applied since the detection of the first case of avian influenza in Japan, excluding surveillance, were completed on 21 April 2006. No new suspected or confirmed case has been detected since that date.
The results of the nation-wide avian influenza surveillance programme undertaken since October 2005 and still in progress are as follows:
a) Serological surveillance
Number of commercial poultry farms* in Japan Number of commercial poultry farms* investigated under the surveillance programme Coverage 3,755 2,419 (all negative) 64.4% *a farm with more than 1,000 poultry
b) Clinical surveillance
Two types of clinical surveillance scheme have been implemented since October 2005. Firstly, all poultry farms are required to promptly notify the relevant Domestic Animals Hygiene Service Center (DAHSC) if they suspect an outbreak of the disease or discover any symptoms consistent with it regardless of the number of dead poultry. No report has been confirmed positive under this scheme. Secondly, the number of dead poultry in each poultry farm is monitored. Under the latter scheme, all commercial poultry farms, including broiler and breeder farms, are required to report the number of the dead poultry to the relevant DAHSC on a monthly basis for the early detection of any symptoms consistent with the disease. No report has been confirmed positive under this scheme.
In accordance with Article 2.7.12.3. of the Terrestrial Animal Health Code, Japan has regained the animal health status as an avian influenza free country, with effect from 21 July 2006.
Final report: yes.

Date of start of the event: 4 July 2006.
Clinical disease: no.
Nature of diagnosis: laboratory.

Description of affected population: a sheep aged 37 months. The head of the sheep had been sent to the Central Veterinary Institute (CVI) in Debrecen within the framework of the National Monitoring Programme for Transmissible Spongiform Encephalopathies.
In the affected farm, two flocks are kept in separate buildings. The positive animal originated from the first flock, which contained 1,193 sheep (1,038 ewes, 55 rams, 100 young sheep under 12 months) when the event started. In the first flock 46 sheep (30 ewes and 16 young animals) have died until now. Samples from 28 dead ewes were sent to the Central Veterinary Institute (CVI) in Debrecen and all results were negative. (The other two ewes were unsuitable for testing). The second flock contained 922 young female sheep when the event started, but until now only two of them have died. These animals are not the progeny of ewes in the first flock, and originated from a different holding.
Diagnosis:
Laboratory where diagnostic tests were performed Species examined Diagnostic tests used Date Results Central Veterinary Institute (CVI), Debrecen ovi Biorad TeSeE rapid test 7 July 2006 positive Central Veterinary Institute (CVI), Budapest ovi immunoblotting 20 July 2006 positive Primary discriminatory immunoblotting indicated that the case could be ascribed to the atypical form of scrapie. The genotyping of the animal is in progress. The CVI will send samples to the European Community Reference Laboratory for further investigations.
Source of outbreak or origin of infection: unknown or inconclusive.
Control measures
A. Undertaken:
- quarantine;
- movement control in the affected farm;
- destruction of the whole body of the slaughtered sheep as "specified risk material".
B. To be undertaken:
- stamping out: the whole population of the first sheep flock on the affected farm will be killed soon and samples will be taken from the killed animals according to Annex III, Chapter A, Part II, point 5 of Regulation (EC) No 999/2001. The whole carcasses of these animals will be destroyed as category 1 material in line with Regulation (EC) No 1774/2002. If the atypical scrapie case is confirmed by the CRL and the result of the epidemiological inquiry confirms that there were not any movements from the first flock to the second one, the animals in the second flock will not been killed.
- screening;
- disinfection of infected premises/establishment(s).
