additiv e for all animal species 
(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(1) of Regulation (EC) No 1831/2003, an application was submitte d for the 
author isation of a preparation of Pediococcus acidilactici CNCM I-4622. That application was accompanied 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 a preparation of Pediococcus acidilactici CNCM I-4622 as a feed additive 
for all animal species, to be classif ied in the additive categor y ‘technological additives’ and in the functional groups 
‘acidity regulator s’ and ‘hygiene condition enhancers’.
(4) The European Food Safet y Author ity (‘the Author ity’) concluded in its opinion of 29 June 2022 (2)that, under the 
proposed conditions of use, the preparation of Pediococcus acidilactici CNCM I-4622 does not have adverse effects on 
animal health, consumer safety or the environment. It also concluded that it is considered a respirato ry sensitiser , but 
not irritant to eyes/skin or a skin sensitiser . The Auth ority further concluded that the preparation showed a potential 
to reduce the pH and the growth of colif orms in liquid feeds. It also verified the repor t on the methods of analysis of 
the feed additive in feed submitte d by the Reference Laboratory set up by Regulation (EC) No 1831/2003.
(5) The assessment of the preparation of Pediococcus acidilactici CNCM I-4622 shows that the conditions for 
author isation, as provided for in Article 5 of Regulation (EC) No 1831/2003, are satisfied. According ly, the use of 
this preparation should be author ised. The Commission considers that appropr iate protective measures should be 
taken to prevent adverse effects on human health, in particular as regards the users of the 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,
HAS ADOPTED THIS REGUL ATION:
Article 1
1. The preparation specif ied in the Annex, belonging to the additive catego ry ‘techn ological additives ’ and to the 
functional group ‘acidity regulator s’, is author ised as an additive in animal nutr ition, subject to the conditions laid down in 
that Annex.
2. The preparation specif ied in the Annex, belonging to the additive catego ry ‘techn ological additives ’ and to the 
functional group ‘hygiene condition enhancers’, is author ised as an additive in animal nutr ition, subject to the conditions 
laid down in that Annex.
