Hansen A/S) and amending Implementing Regulation (EU) 2020/1762 as regards the terms of the authorisation of a preparation of Bacillus subtilis DSM 32324, Bacillus subtilis DSM 32325 and Bacillus amyloliquefaciens DSM 25840 as a feed additive for all poultry species for fattening or reared for laying or reared for breeding
Issued by European Commission
· Directorate-General for Health and Food Safety
**Executive Summary**
This Commission Implementing Regulation (EU) 2025/2576, dated 18 December 2025, authorises the use of a preparation of Bacillus subtilis DSM 32324, Bacillus subtilis DSM 32325, and Bacillus amyloliquefaciens DSM 25840 as a feed additive for all poultry species for laying or breeding. It also amends Implementing Regulation (EU) 2020/1762 concerning the same preparation for poultry species for fattening or reared for laying or reared for breeding. A transitional period is provided until 8 July 2026 for premixtures, and 8 January 2027 for compound feed and feed materials, produced and labelled before 8 January 2026, to be placed on the market and used.
**Key Points / Main Content**

* The authorisation is for all poultry species for laying or breeding.
* The additive can be used via water for drinking.
* **Amendment to Implementing Regulation (EU) 2020/1762:**
* The annex to Implementing Regulation (EU) 2020/1762 is replaced.

concerning the authorisation of a preparation of Bacillus subtilisDSM 32324, Bacillus subtilisDSM
32325 and Bacillus amyloliquefaciensDSM 25840 as a feed additive for all poultry species for laying or
for breeding (holder of authorisation: Chr. Hansen A/S) and amending Implementing Regulation
(EU) 2020/1762 as regards the terms of the authorisation of a preparation of Bacillus subtilisDSM

poultry species for fattening or reared for laying or reared for breeding
(Text with EEA relevance)
THE EUROPEAN COMMISSION,
Having regard to the Treaty on the Functioning of the European Union,
Having regard to Regulation (EC) No 1831/2003 of the European Parliament and of the Council of 22 September 2003 on
additives for use in animal nutrition(1), and in particular Article 9(2) and Article 13(3) thereof,
Whereas:
(1) Regulation (EC) No 1831/2003 provides for the authorisation of additives for use in animal nutrition and for the
grounds and procedures for granting such an authorisation.
(2) A preparation of Bacillus subtilisDSM 32324, Bacillus subtilisDSM 32325 and Bacillus amyloliquefaciensDSM 25840
was authorised for a period of 10 years as a feed additive for all poultry species for fattening or reared for laying or
reared for breeding by Commission Implementing Regulation (EU) 2020/1762(2).
(3) In accordance with Article 7 of Regulation (EC) No 1831/2003, an application was submitted for the authorisation of
a preparation of Bacillus subtilisDSM 32324, Bacillus subtilisDSM 32325 and Bacillus amyloliquefaciensDSM 25840.
That application was accompanied by the particulars and documents required under Article 7(3) of Regulation (EC)
No 1831/2003.
(4) The application concerns the authorisation of the preparation of Bacillus subtilis DSM 32324, Bacillus subtilis DSM
32325 and Bacillus amyloliquefaciensDSM 25840 as a feed additive for all poultry species for laying or for breeding,
requesting that additive to be classified in the category ‘zootechnical additives’ and in the functional group ‘gut flora
stabilisers’.
(5) In accordance with Article 13(3) of Regulation (EC) No 1831/2003, an application was submitted for the
modification of the terms of the authorisation of the preparation of Bacillus subtilisDSM 32324, Bacillus subtilisDSM
32325 and Bacillus amyloliquefaciens DSM 25840 as laid down in Implementing Regulation (EU) 2020/1762 as
regards the use for all poultry species for fattening or reared for laying or reared for breeding. That application
concerned the modification of the terms of the existing authorisation by introducing a new formulation with
a 10-fold increased concentration of the active agents in the additive (from 3,2 × 109to 3,2 × 1010colony forming
units (CFU)/g additive).

(2) Commission Implementing Regulation (EU) 2020/1762 of 25 November 2020 concerning the authorisation of a preparation of
Bacillus subtilis DSM 32324, Bacillus subtilis DSM 32325 and Bacillus amyloliquefaciens DSM 25840 as a feed additive for all poultry
species for fattening or reared for laying or reared for breeding (holder of authorisation Chr. Hansen A/S) (OJ L 397 26.11.2020, p. 14,

OJ L, 19.12.2025
(6) The European Food Safety Authority (‘the Authority’) concluded in its opinion of 20 March 2025(3)that, under the
proposed conditions of use, the preparation of Bacillus subtilisDSM 32324, Bacillus subtilisDSM 32325 and Bacillus
amyloliquefaciensDSM 25840 is safe for the target species, including poultry species for laying and breeding, as well
as for consumers and the environment. The Authority also concluded that the preparation of Bacillus subtilis DSM
32324, Bacillus subtilisDSM 32325 and Bacillus amyloliquefaciensDSM 25840, in both forms of the additive are non-
irritant to the eyes but are considered skin and respiratory sensitisers, and any exposure through skin and respiratory
tract is considered a risk. The Authority further concluded that the preparation of Bacillus subtilisDSM 32324, Bacillus
subtilisDSM 32325 and Bacillus amyloliquefaciensDSM 25840 has the potential to be efficacious in all poultry at 1,6 ×
109 CFU/kg feed and 5,4 × 108 CFU/L water for drinking. It did not consider that there is a need for specific
requirements of post-market monitoring.
(7) The Reference Laboratory set up by Regulation (EC) No 1831/2003 considered that the conclusions and
recommendations reached in a previous assessment concerning another application for the authorisation of the
same additive and verified by the Authority in its opinion of 20 March 2020(4) are valid and applicable for the
current application. In accordance with Article 5(4), point (a), of Commission Regulation (EC) No 378/2005(5), an
evaluation report of the Reference Laboratory was therefore not required.
(8) In view of the above, the Commission considers that the preparation of Bacillus subtilisDSM 32324, Bacillus subtilis
DSM 32325 and Bacillus amyloliquefaciensDSM 25840 satisfies the conditions provided for in Article 5 of Regulation
(EC) No 1831/2003. Accordingly, the use of that preparation should be authorised for all poultry species for laying or
for breeding. In addition, the Commission considers that appropriate protective measures should be taken to prevent
adverse effects on the health of the users of the additive.
(9) In addition, the Commission considers that the authorisation of the preparation of Bacillus subtilis DSM 32324,
Bacillus subtilis DSM 32325 and Bacillus amyloliquefaciens DSM 25840 still meets the conditions provided for in
Article 5 of Regulation (EC) No 1831/2003 when the terms of that authorisation are modified as regards the use for
all poultry species for fattening or reared for laying or reared for breeding, by introducing a new formulation with
a 10-fold increased concentration of the active agents in the additive (from 3,2 × 109to 3,2 × 1010colony forming
units (CFU)/g additive). Implementing Regulation (EU) 2020/1762 should therefore be amended accordingly.
(10) Since safety reasons do not require the immediate application of the modifications to the conditions of authorisation
of the preparation of Bacillus subtilis DSM 32324, Bacillus subtilis DSM 32325 and Bacillus amyloliquefaciens DSM
25840 for all poultry species for fattening or reared for laying or reared for breeding, it is appropriate to provide for
a transitional period for interested parties to prepare themselves to meet the new requirements resulting from the
modification of the authorisation.
(11) The measures provided for in this Regulation are in accordance with the opinion of the Standing Committee on
Plants, Animals, Food and Feed,
HAS ADOPTED THIS REGULATION:
