concer ning the author isation of a preparation of Bacillus subtilis CNCM I-4606, CNCM I-5043 and

(Text with EEA relevance) 
THE EUR OPEAN COMMISSION,
Havi ng regar d to the Treaty on the Functioning of the European Union,
Havi ng rega rd to Regulation (EC) No 1831/2003 of the European Parliament and of the Council of 22 Sept ember 2003 on 
additives for use in animal nutr ition (1), and in particular Article 9(2) thereof,
Whereas:
(1) Regulation (EC) No 1831/2003 provid es for the author isation of additives for use in animal nutr ition and for the 
grounds and procedures for granting such an author isation.
(2) In accordance with Article 7 of Regulation (EC) No 1831/2003, an application was submitted for the author isation 
of a preparation of Bacillus subtilis CNCM I-4606, CNCM I-5043 and CNCM I-4607 and Lactococcus lactis CNCM 
I-4609. That application was accompan ied by the particulars and documents required under Article 7(3) of 
Regulation (EC) No 1831/2003.
(3) The application concer ns the author isation of the preparation of Bacillus subtilis CNCM I-4606, CNCM I-5043 and 
CNCM I-4607 and Lactococcus lactis CNCM I-4609 as a feed additive for all animal species, requesting that additive 
to be classifie d in the categor y ‘technological additives’ and in the functional group ‘hygiene condition enhancers’.
(4) The European Food Safety Author ity (‘the Author ity’) concluded in its opinions of 30 Sept ember 2021 (2)and of 
1 Febr uary 2023 (3)that, under the proposed conditions of use, which exclude the use of the additive in 
commercial premixtures containing trace elements or preser vatives, the preparation of Bacillus subtilis CNCM 
I-4606, CNCM I-5043 and CNCM I-4607 and Lactococcus lactis CNCM I-4609 is safe for the target species, 
consumers and the environment. It also concluded that the preparation is not irritant to skin or eyes or a skin 
sensitiser but that, given the proteinaceous nature of the active agent, it should be considered a respirato ry 
sensitiser . The Author ity further concluded that the additive at the minimum proposed inclusion level showed 
poten tial to reduce Salmonella Typhimur ium growth in feed with high moisture cont ent (60–90 % moisture) and 
note d that the use of this additive cannot be considered as a replacement for the standard hygiene farming 
conditions. The Author ity also verified the repor t on the method of analysis of the feed additive in feed submitted 
by the Reference Laboratory set up by Regulation (EC) No 1831/2003.
(5) In view of the above, the Commission considers that the preparation of Bacillus subtilis CNCM I-4606, CNCM I-5043 
and CNCM I-4607 and Lactococcus lactis CNCM I-4609 satisfi es the conditions provided for in Article 5 of Regulation 
(EC) No 1831/2003. According ly, the use of that preparation should be author ised. In addition, the Commission 
considers that appropr iate prot ective measures should be taken to prevent adverse effects on the health of the users 
of that additive.
(6) The measures provid ed for in this Regulation are in accordance with the opinion of the Standing Committ ee on 
Plants, Animals, Food and Feed,
