THE COMMISSION OF THE EUROPEAN COMMUNITIES,

Having regard to the Treaty establishing the European Community,

Having regard to Council Decision 90/424/EEC of 26 June 1990 on expenditure in the veterinary field (1) and in particular Article 20 thereof,

Whereas:

| (1) | Decision 90/424/EEC provides for a Community financial contribution for the undertaking of technical and scientific measures necessary for the development of Community veterinary legislation and for veterinary education and training. |

(1)

Decision 90/424/EEC provides for a Community financial contribution for the undertaking of technical and scientific measures necessary for the development of Community veterinary legislation and for veterinary education and training.

| (2) | The Scientific Committee on Animal Health and Animal Welfare in a report of 27 June 2000 recommended that surveys be carried out on poultry flocks and wild birds for avian influenza, in particular to determine the prevalence of infections with avian influenza virus subtypes H5 and H7. |

The Scientific Committee on Animal Health and Animal Welfare in a report of 27 June 2000 recommended that surveys be carried out on poultry flocks and wild birds for avian influenza, in particular to determine the prevalence of infections with avian influenza virus subtypes H5 and H7.

| (3) | Council Directive 92/40/EEC of 19 May 1992 introducing Community measures for the control of avian influenza (2) defines Community control measures to be applied in the event of an outbreak of avian influenza in poultry. However, it does not provide for regular surveys of that disease in poultry and wild birds. |

(4)

Accordingly, Commission Decisions 2002/649/EC (3) and 2004/111/EC (4) provided for the submission of surveillance programmes concerning avian influenza by the Member States to the Commission.

| (5) | Commission Decisions 2002/673/EC (5) and 2004/630/EC (6) approved programmes submitted by the Member States for surveys of avian influenza in poultry and wild birds for the periods specified in those programmes. |

(5)

Commission Decisions 2002/673/EC (5) and 2004/630/EC (6) approved programmes submitted by the Member States for surveys of avian influenza in poultry and wild birds for the periods specified in those programmes.

| (6) | During those surveys, the presence of different subtypes of H5 and H7 avian influenza viruses has been detected in several Member States. Although the current prevalence of avian influenza viruses can be considered rather low, it is important to continue and to improve the surveillance so as to better understand the epidemiology of the low pathogenic avian influenza viruses and prevent that viruses do not circulate unnoticed in the poultry population. The results of the surveys carried out in the Member States have proven to be very useful in monitoring the presence of avian influenza virus subtypes that could present a substantial risk if they mutated into a more virulent form. Taking into account the results obtained and the current disease situation in the Community, it is appropriate to increase the total amount of Community contribution to ensure increased surveillance. |

ANNEX

Programmes for surveillance of avian influenza in poultry and wild birds to be carried out in the Member States in 2005 and 2006

A.   OBJECTIVES

| 1. | To estimate the prevalence of infections with avian influenza virus subtypes H5 and H7 in different species of poultry by repeating previous screening exercises provided for in Decisions 2004/111/EC and 2004/630/EC in a modified, more targeted manner. |
| --- | --- |

1.

| 2. | To continue surveillance for avian influenza on a voluntary basis in wild birds. The outcome of such surveillance should further provide valuable information for an early warning system of strains that may be introduced into poultry flocks from wild birds. |
| --- | --- |

2.

| 3. | To contribute to the knowledge on the threats of avian influenza to animal health from wildlife. |
| --- | --- |

3.

| 4. | To foster the connection and integration of human and veterinary networks for influenza surveillance. |
| --- | --- |

4.

B.   GENERAL REQUIREMENTS AND CRITERIA FOR SURVEYS IN POULTRY

| 1. | Sampling shall cover a period appropriate to production periods for each poultry category as required. For example, in many Member States a large slaughter of poultry (in particular turkeys and geese) takes place around Christmas. Sampling shall not extend beyond 31 January 2006. |
| --- | --- |

1.

| 2. | 31 March 2006 shall be the date for the submission of the final survey results. |
| --- | --- |

2.
