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 and renewing such author isation.
(2) The preparation of Lactiplantibacillus plantar um DSM 19457 (previously taxonomically identif ied as Lactobacillus 
plantar um DSM 19457) was author ised for a period of 10 years as a feed additive for all animal species by 
Commission Implementing Regulation (EU) No 1065/2012 (2).
(3) 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 preparation of Lactiplantibacillus plantar um DSM 19457 as a feed additive for all animal 
species, requesting the additive to be classif ied in the additive catego ry ‘technological 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.
(4) The European Food Safety Auth ority (‘the Author ity’) concluded in its opinion of 22 November 2022 (3)that the 
applicant has provided evidence that the preparation of Lactiplantibacillus plantar um DSM 19457 remains safe for all 
animal species, the consumers and the environment under the conditions of use currently author ised. The Author ity 
also concluded that the additive is not irritant to skin or eyes but that, owing to its proteina ceous nature, it should be 
considered a respirato ry sensitiser . The Author ity could not conclude, in the absence of data, on the skin 
sensitisation poten tial of the additive.
(5) In accordance with Article 5(4), point (c), of Commission Regulation (EC) No 378/2005 (4), the Reference 
Laboratory set up by Regulation (EC) No 1831/2003 considered that the conclusions and recommendations 
reach ed in the previous assessment are valid and applicable for the current application.

(2)Commission Implementing Regulation (EU) No 1065/2012 of 13 November 2012 concer ning the author isation of preparations of 
Lactobacillus plantar um (DSM 23375, CNCM I-3235, DSM 19457, DSM 16565, DSM 16568, LMG 21295, CNCM MA 18/5U, NCIMB

(4)Commission Regulation (EC) No 378/2005 of 4 March 2005 on detailed rules for the implement ation of Regulation (EC) 
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).EN Offi cial Jour nal of the European Union 12.7.2023 L 177/59  (6) The assessment of the preparation of Lactiplantibacillus plantar um DSM 19457 shows that the conditions for 
author isation, as provid ed for in Article 5 of Regulation (EC) No 1831/2003, are satisfied. According ly, the 
author isation of that preparation should be renewed.
(7) The Commission considers that appropr iate protect ive measures should be taken to prevent adverse effects on the 
health of the users of the additive. Those protective measures should be without prejudice to other worker safety 
requirements under Union law.
(8) As a consequence of the renewal of the author isation of the preparation of Lactiplantibacillus plantar um DSM 19457 
as a feed additive, Implementing Regulation (EU) No 1065/2012 should be amended according ly.
(9) Since safet y reasons do not require the immediate application of the modifications to the conditions of author isation 
of the preparation of Lactiplantibacillus plantar um DSM 19457, it is appropr iate to provide for a transitional period 
for inter ested parties to prepare themselves to meet the new requirements resulting from the renewal of the 
author isation.
(10) 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,
