COMMISSION IMPLEMENTING REGUL ATION (EU) 2023/1405 
of 3 July 2023

preparation of Lactiplantibacillus planta rum ATCC 55942 as feed additiv es 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 author isation. Article 10(7) of Regulation (EC) No 1831/2003 sets out 
specifi c provisions for the placing on the mark et and use of products used in the Union as silage additives at the 
date that Regulation became applicable.
(2) In accordance with Article 10(1), point (b), of Regulation (EC) No 1831/2003, the preparations of Lactiplantibacillus 
plantar um ATCC 55058 and ATCC 55942 (previously taxonomically identif ied as Lactobacillus plantar um ATCC 
55058 and ATCC 55942) were entered in the Registe r of Feed Additives as existing products belonging to the 
functional group of silage additives, for all animal species.
(3) In accordance with Article 10(7) of Regulation (EC) No 1831/2003, in conjunction with Article 7 and Article 10(2) 
thereof, applications were submitte d for the author isation of the preparations of Lactiplantibacillus plantar um ATCC 
55058 and ATCC 55942 as feed additives for all animal species, requesting those additives to be classified in the 
catego ry ‘technological additives ’ and in the functional group ‘silage additives’. Those applications were 
accompan ied by the particulars and documents required under Article 7(3) of Regulation (EC) No 1831/2003.
(4) The European Food Safety Auth ority (‘the Author ity’) concluded in its opinion of 23 May 2012 (2)that the use of the 
preparations of Lactiplantibacillus plantar um ATCC 55058 and ATCC 55942 in the production of silage is presumed 
safe for the target species, consumers of products from animals fed with treated silage and the environment, but 
found no evidence that those two preparations have a beneficial effect on the preser vation of nutr ients and 
theref ore could not conclude on their effic acy. In addition, the Auth ority noted that according to their gener ic 
mater ial safety data sheet, the preparations may cause irritation on prolonged contact with skin and eyes and 
concluded that their pote ntial as skin and respirato ry sensitisers should be considered due to the prot einaceous 
nature of the active agents.
(5) In its opinion of 10 October 2013 (3), the Auth ority still could not conclude on the efficacy of those preparations 
due to the absence of any significant evidence of nutr ient preser vation. Howe ver, based on three new efficacy 
studies provided by the applicant as supplementar y information, the Auth ority eventually concluded in its opinion 
of 27 Sept ember 2022 (4)that the preparations of Lactiplantibacillus plantar um ATCC 55058 and ATCC 55942 have 
the poten tial to improve the ensiling process by reducing protein degradation in all type of forag es as indicated by 
the reduction of ammonia production.

(4)EFSA Journal 2022; 20(10):7602.EN Offi cial Jour nal of the European Union 4.7.2023 L 169/31  (6) The assessment of the preparations of Lactiplantibacillus plantar um ATCC 55058 and ATCC 55942 shows that the 
conditions for author isation, as provid ed for in Article 5 of Regulation (EC) No 1831/2003, are satisfi ed. 
According ly, the use of those preparations should be author ised. The Commission considers that appropr iate 
prote ctive measures should be taken to prevent adverse effects on the health of the users of the additive.
(7) Since safet y reasons do not require the immediate application of the modifications to the conditions of author isation 
of the preparations concer ned, it is appropr iate to provide for a transitional period for the interested parties to 
prepare themselves to meet the new requirements resulting from the author isation.
(8) 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
Author isation
The preparations specifi ed in the Annex, belonging to the additive catego ry ‘techn ological additives ’ and to the functional 
group ‘silag e additives’, are author ised as additives in animal nutr ition, subject to the conditions laid down in that Annex.
Article 2
Transitional measures
The preparations specifi ed in the Annex and feed containing them, which are produced and labelled before 24 July 2024 in 
accordance with the rules applicable before 24 July 2023 may continue to be placed on the market and used until the 
existing stoc ks are exhausted.
Article 3
Entr y into force
