Commission Implementing Regulation (EU) 2026/356 of 18 February 2026 concerning the authorisation of a preparation of endo-1,4-beta-xylanase produced with Bacillus subtilis LMG S-15136 as a feed additive for gestating sows (holder of authorisation: Puratos NV)
Issued by European Commission
· Directorate-General for Health and Food Safety
**Executive Summary**
This document is Commission Implementing Regulation (EU) 2026/356 of 18 February 2026, authorising the use of an endo-1,4-beta-xylanase preparation produced with Bacillus subtilis LMG S-15136 as a feed additive for gestating sows. The regulation is effective as of the twentieth day following its publication in the Official Journal of the European Union, and the authorisation of the additive expires on 11 March 2036.
**Key Points / Main Content**
* **Authorisation:**
* The preparation of endo-1,4-beta-xylanase produced with Bacillus subtilis LMG S-15136 is authorised as a zootechnical additive (digestibility enhancer) in animal nutrition.
* The minimum activity of the additive is 400 IU/g.
* The maximum content in complete feed is 10 IU/kg (with 12% moisture content).
* **Composition and Characteristics:**
* The additive can be in solid or liquid form.
* It should be characterised by endo-1,4-beta-xylanase (EC 3.2.1.8) produced with Bacillus subtilis LMG S-15136.
* **Analytical Methods:**
* The method for quantifying xylanase activity in the feed additive is a colorimetric method measuring reducing sugars released from birchwood xylan in the presence of 3,5-dinitrosalicylic acid (DNS).
* For premixes and compound feed the method is a colorimetric method measuring water-soluble dye released by xylanase from azurine cross-linked wheat arabinoxylan substrates.
* **Other Provisions:**
* The storage conditions and stability of the additive and premixtures, including stability to heat treatment, must be indicated in the directions for use.
* Feed business operators must establish operational procedures and organisational measures to address potential risks resulting from the use of the additive and its premixes.
* If these risks cannot be eliminated, the additive and premixes should be used with personal breathing, skin, and eye protective equipment.

of 18 February 2026
concerning the authorisation of a preparation of endo-1,4-beta-xylanase produced with Bacillus
subtilisLMG S-15136 as a feed additive for gestating sows (holder of authorisation: Puratos NV)
(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) 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) In accordance with Article 7 of Regulation (EC) No 1831/2003, an application was submitted for the authorisation of
a preparation of endo-1,4-beta-xylanase produced with Bacillus subtilis LMG S-15136. That application was
accompanied by the particulars and documents required under Article 7(3) of Regulation (EC) No 1831/2003.
(3) The application concerns the authorisation of the preparation of endo-1,4-beta-xylanase produced with Bacillus
subtilis LMG S-15136 as a feed additive for gestating sows, requesting that additive to be classified in the additive
category ‘zootechnical additives’ and in the functional group ‘digestibility enhancers’.
(4) The European Food Safety Authority (‘the Authority’) concluded in its opinion of 25 June 2025(2) that, under the
proposed conditions of use, the preparation of endo-1,4-beta-xylanase produced with Bacillus subtilisLMG S-15136
is safe for gestating sows, as well as for consumers and the environment. The Authority also concluded that the
preparation of endo-1,4-beta-xylanase produced with Bacillus subtilisLMG S-15136 in both formulations, solid and
liquid, is considered a skin and eye irritant and respiratory sensitiser, and any exposure to this preparation is
considered a risk. The Authority further concluded that the preparation of endo-1,4-beta-xylanase produced with
Bacillus subtilis LMG S-15136 has the potential to be efficacious as a zootechnical additive in sows during the
gestation period at 10 IU/kg complete feed. The Authority did not consider that there is a need for specific
requirements of post-market monitoring.
(5) 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 13 July 2016(3)are valid and applicable for the current
application. In accordance with Article 5(4), point (a), of Commission Regulation (EC) No 378/2005(4), an evaluation
report of the Reference Laboratory was therefore not required.

Laboratory concerning applications for authorisations of feed additives (OJ L 59, 5.3.2005, p. 8, ELI: http://data.europa.eu/eli/reg/

(6) In view of the above, the Commission considers that the preparation of endo-1,4-beta-xylanase produced with
Bacillus subtilis LMG S-15136 satisfies the conditions provided for in Article 5 of Regulation (EC) No 1831/2003.
Accordingly, the use of that preparation should be authorised for gestating sows. 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.
(7) The measures provided for in this Regulation are in accordance with the opinion of the Standing Committee on
Plants, Animals, Food and Feed,
