NCIMB 40788 was author ised for a period of 10 years as a feed additive for all animal species by Commission 
Implementing Regulation (EU) 2019/764 (7).
(8) In accordance with Article 14(1) of Regulation (EC) No 1831/2003, an application was submitted for the renewal of 
the author isation of the preparations of Lactiplantibacillus plantar um CNCM I-3235, Lactiplantibacillus plantar um 
DSM 11672/CNCM I-3736, Pediococcus acidilactici CNCM I-3237, Pediococcus acidilactici DSM 11673/CNCM I-4622,

I-4323/NCIMB 40788 as feed additives for all animal species, requesting the additives to be classifie d in the additive 
catego ry ‘techn ological additives ’ and in the functional group ‘silag e additives’. That application was accompan ied by 
the particulars and documents required under Article 14(2) of that Regulation.
(9) The European Food Safe ty Author ity (‘the Authority’) concluded in its opinion of 31 Januar y 2023 (8)that the 
abov ementioned preparations remain safe for all animal species, the consumers and the environment under the 
existing conditions of author isation. It also concluded that the additives should be considered as respirato ry 
sensitisers. In the absence of data, no conclusions could be drawn on the skin sensitisation, and skin and eye 
irritancy potential of the additives, with the exce ption for Pediococcus acidilactici DSM 11673/CNCM I-4622 that is 
considered non-ir ritant to skin and eyes. It also indicated that there is no need for assessing the efficacy of the 
additives in the conte xt of the renewal of the author isation.
(10) The Reference Laborator y set up by Regulation (EC) No 1831/2003 considered that the conclusions and 
recommendations reac hed in the assessments carried out regar ding the method of analysis of the preparations of

Lentilactobacillus hilgardii CNCM I-4785 and Lentilactobacillus buchner i CNCM I-4323/NCIMB 40788 as feed additives 
in the conte xt of the previous author isations are valid and applicable for the current application. In accordance with 
Article 5(4), point (c) of Commission Regulation (EC) No 378/2005 (9), an evaluation repor t of the Reference 
Laboratory is theref ore not required.

No 1831/2003 of the European Parliament and of the Council as regards the duties and tasks of the Community Reference 
Laborato ry concer ning applications for author isations of feed additives (OJ L 59, 5.3.2005, p. 8).OJ L, 17.1.2024 EN  ELI: http://data.europa.eu/eli/reg_impl/2024/251/oj 3/11(11) In view of the above, the Commission considers that the preparations of Lactiplantibacillus plantar um CNCM I-3235, 
Lactiplantibacillus plantar um DSM 11672/CNCM I-3736, Pediococcus acidilactici CNCM I-3237, Pediococcus acidilactici

Lentilactobacillus buchner i CNCM I-4323/NCIMB 40788 satisfy the conditions provi ded for in Article 5 of Regulation 
(EC) No 1831/2003. According ly, the author isation of those additives should be renewed. In addition, the 
Commission considers that appropr iate protective measures should be taken to prevent adverse effects on the 
health of the users of the additive.
(12) As a consequence of the renewal of the author isation of the preparations of Lactiplantibacillus plantar um CNCM 
I-3235, Lactiplantibacillus plantar um DSM 11672/CNCM I-3736, Pediococcus acidilactici CNCM I-3237, Pediococcus

No 1065/2012, (EU) No 1119/2012, (EU) No 1113/2013 and (EU) No 304/2014 should be amended and 
Implementing Regulations (EU) No 990/2012 and (EU) 2019/764 should be repealed.
(13) Since safet y reasons do not require the immediat e application of the modif ications to the conditions of the 
author isation of the preparations of Lactiplantibacillus plantar um CNCM I-3235, Lactiplantibacillus plantar um 
DSM 11672/CNCM I-3736, Pediococcus acidilactici DSM 11673/CNCM I-4622, Acidipropionibacter ium acidipr opionici
