of 30 April 2008

concerning the authorisation of astaxanthin dimethyldisuccinate as a feed additive

(Text with EEA relevance)


Having regard to the Treaty establishing the European Community,

Having regard to Regulation (EC) No 1831/2003 of the European Parliament and of the Council of 22 September 2003 on additives for use in animal nutrition (1), and in particular Article 9(2) thereof,



Regulation (EC) No 1831/2003 provides for the authorisation of additives for use in animal nutrition and for the grounds and procedures for granting such authorisation.


In accordance with Article 7 of Regulation (EC) No 1831/2003, an application was submitted for the authorisation of the preparation set out in the Annex to this Regulation. That application was accompanied by the particulars and documents required under Article 7(3) of Regulation (EC) No 1831/2003.


The application concerns authorisation of the preparation of astaxanthin dimethyldisuccinate as a feed additive for salmon and trout, to be classified in the additive category ‘sensory additives’.


The European Food Safety Authority (the Authority) concluded in its opinion of 17 October 2007 that astaxanthin dimethyldisuccinate does not have an adverse effect on animal health, human health or the environment (2). It further concluded that astaxanthin dimethyldisuccinate does not present any other risk which would, in accordance with Article 5(2) of Regulation (EC) No 1831/2003, exclude authorisation. It does not consider that there is a need for specific requirements of post market monitoring. This opinion also verifies the report on the method of analysis of the feed additive in feed submitted by the Community Reference Laboratory set up by Regulation (EC) No 1831/2003.


The assessment of that preparation shows that the conditions for authorisation, provided for in Article 5 of Regulation (EC) No 1831/2003, are satisfied. Accordingly, the use of that preparation should be authorised, as specified in the Annex to this Regulation.


The measures provided for in this Regulation are in accordance with the opinion of the Standing Committee on the Food Chain and Animal Health,


Article 1

The preparation specified in the Annex, belonging to the additive category ‘sensory additives’ and to the functional group ‘a(ii) Colourants; substances which when fed to animals add colours to food of animal origin’, is authorised as an additive in animal nutrition subject to the conditions laid down in that Annex.

Article 2

This Regulation shall enter into force on the 20th day following that of its publication in the Official Journal of the European Union.

This Regulation shall be binding in its entirety and directly applicable in all Member States.
