of 5 January 2023

concerning the authorisation of a preparation of endo-1,4-beta-glucanase from Aspergillus niger CBS 120604, a preparation of endo-1,3(4)-beta-glucanase from Aspergillus neoniger MUCL 39199, a preparation of endo-1,4-beta-xylanase from Trichoderma citrinoviride MUCL 39203 and a preparation of endo-1,4-beta-xylanase from Trichoderma citrinoviride CBS 614.94 as feed additives for all animal species

(Text with EEA relevance)

THE EUROPEAN COMMISSION,

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

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,

Whereas:

| (1) | 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 an authorisation. Article 10(2) of that Regulation provides for the re-evaluation of additives authorised pursuant to Council Directive 70/524/EEC (2). Article 10(7) of Regulation (EC) No 1831/2003 sets out specific provisions for the placing on the market and use of products used in the Union as silage additives. |

Article 10(2) of that Regulation provides for the re-evaluation of additives authorised pursuant to Council Directive 70/524/EEC (2). Article 10(7) of Regulation (EC) No 1831/2003 sets out specific provisions for the placing on the market and use of products used in the Union as silage additives.

| (2) | The preparations of endo-1,4-beta-glucanase from Aspergillus niger CBS 120604, endo-1,3(4)-beta-glucanase from Aspergillus neoniger MUCL 39199, endo-1,4-beta-xylanase from Trichoderma citrinoviride MUCL 39203 and endo-1,4-beta-xylanase from Trichoderma citrinoviride CBS 614.94 were entered in the Register of feed additives as existing products (3) for all animal species belonging to the functional group of silage additives, in accordance with Article 10(1), point (b), of Regulation (EC) No 1831/2003. |

(2)

The preparations of endo-1,4-beta-glucanase from Aspergillus niger CBS 120604, endo-1,3(4)-beta-glucanase from Aspergillus neoniger MUCL 39199, endo-1,4-beta-xylanase from Trichoderma citrinoviride MUCL 39203 and endo-1,4-beta-xylanase from Trichoderma citrinoviride CBS 614.94 were entered in the Register of feed additives as existing products (3) for all animal species belonging to the functional group of silage additives, in accordance with Article 10(1), point (b), of Regulation (EC) No 1831/2003.

| (3) | In accordance with Article 10(7) of Regulation (EC) No 1831/2003 in conjunction with Article 10(2) and Article 7 thereof, an application was submitted for the authorisation of the preparations of endo-1,4-beta-glucanase from Aspergillus niger CBS 120604, endo-1,3(4)-beta-glucanase from Aspergillus neoniger MUCL 39199, endo-1,4-beta-xylanase from Trichoderma citrinoviride MUCL 39203 and endo-1,4-beta-xylanase from Trichoderma citrinoviride CBS 614.94 as feed additives for all animal species. The applicant requested the preparations to be classified in the additive category ‘technological additives’ and the functional group ‘silage additives’. The application was accompanied by the particulars and documents required under Article 7(3) of Regulation (EC) No 1831/2003. |

In accordance with Article 10(7) of Regulation (EC) No 1831/2003 in conjunction with Article 10(2) and Article 7 thereof, an application was submitted for the authorisation of the preparations of endo-1,4-beta-glucanase from Aspergillus niger CBS 120604, endo-1,3(4)-beta-glucanase from Aspergillus neoniger MUCL 39199, endo-1,4-beta-xylanase from Trichoderma citrinoviride MUCL 39203 and endo-1,4-beta-xylanase from Trichoderma citrinoviride CBS 614.94 as feed additives for all animal species. The applicant requested the preparations to be classified in the additive category ‘technological additives’ and the functional group ‘silage additives’. The application was accompanied by the particulars and documents required under Article 7(3) of Regulation (EC) No 1831/2003.

| (4) | The European Food Safety Authority (‘the Authority’) concluded in its opinions of 7 March 2018 (4) and 29 June 2022 (5), that, under the proposed conditions of use, the preparations concerned do not have adverse effects on animal health, consumer health or the environment. The Authority also concluded that in the absence of data, no conclusion could be drawn on the skin and eye irritancy of the additives and on their skin sensitisation potential. Owing to the proteinaceous nature of the active substances, these preparations should be considered to be potential respiratory sensitisers. The Authority further concluded in its opinion of 29 June 2022 that the preparations concerned have the potential to improve the production of silage from easy, moderate and difficult to ensile forage materials. It also verified the report on the methods of analysis of the feed additives in feed submitted by the Reference Laboratory set up by Regulation (EC) No 1831/2003. |

Accordingly, the use of those preparations should be authorised. The Commission considers that appropriate protective measures should be taken to prevent adverse effects on human health, in particular as regards the users of the additive. |
