COMMISSION REGULATION (EU) No 175/2010

of 2 March 2010

implementing Council Directive 2006/88/EC as regards measures to control increased mortality in oysters of the species Crassostrea gigas in connection with the detection of Ostreid herpesvirus 1 μvar (OsHV-1 μvar)

(Text with EEA relevance)

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Council Directive 2006/88/EC of 24 October 2006 on animal health requirements for aquaculture animals and products thereof, and on the prevention and control of certain diseases in aquatic animals (1), and in particular Articles 41(3) and 61(3) thereof,

Whereas:

| (1) | Directive 2006/88/EC lays down the animal health requirements to be applied for the placing on the market of aquaculture animals and products thereof. In addition, it lays down minimum preventive measures to be applied in the event of a suspicion of, or an outbreak of certain diseases in aquatic animals. |

(1)

Directive 2006/88/EC lays down the animal health requirements to be applied for the placing on the market of aquaculture animals and products thereof. In addition, it lays down minimum preventive measures to be applied in the event of a suspicion of, or an outbreak of certain diseases in aquatic animals.

| (2) | Article 41 of that Directive provides that Member States are to take appropriate measures to control an emerging disease situation and prevent that disease from spreading. In the case of an emerging disease situation, the Member State concerned is to inform the Commission, the Member States and EFTA Member States without delay, where the findings are of epidemiological significance to another Member State. |

Article 41 of that Directive provides that Member States are to take appropriate measures to control an emerging disease situation and prevent that disease from spreading. In the case of an emerging disease situation, the Member State concerned is to inform the Commission, the Member States and EFTA Member States without delay, where the findings are of epidemiological significance to another Member State.

| (3) | Increased mortality in oysters of the species Crassostrea gigas (Crassostrea gigas oysters) were detected in several areas in France and in Ireland during the late spring and summer of 2008. It was attributed to a combination of adverse environmental factors together with the presence of bacteria of the genus Vibrio and the presence of the Ostreid herpesvirus-1 (OsHV-1) including a newly described genotype of that virus named OsHV-1 μvar. |

PART B

Diagnostic methods of detecting OsHV-1 μvar

1.   Scope

This procedure explains a standard diagnostic method to be used for OsHV-1 μvar detection and identification by Polymerase Chain Reaction (hereinafter PCR). It allows distinguishing between OsHV-1 and OsHV-1 μvar.

When appropriate, in order to optimise the reaction conditions and to suit the equipment and conditions in their own laboratory, the laboratories may apply modifications to the methods described in this Annex, provided that an equal sensitivity and specificity can be demonstrated.

2.   Definition

OsHV-1 μvar is defined in Article 1 of this Regulation.

3.   Equipment and environmental conditions

The diagnostic test used for OsHV-1 μvar detection and identification by PCR requires the equipment and environmental conditions classically used for PCR assays as follows:
