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 and renewing such an authorisation.
(2) A preparation of Saccharomyces cerevisiaeNCYC R404, was authorised for a period of 10 years as a feed additive for
dairy cows by Commission Implementing Regulation (EU) 2015/502(2).
(3) In accordance with Article 14(1) of Regulation (EC) No 1831/2003, an application was submitted for the renewal of
the authorisation of the preparation of Saccharomyces cerevisiae NCYC R404 as a feed additive for dairy cows,
requesting the additive to be classified in the additive category ‘zootechnical additives’ and in the functional group
‘gut flora stabilisers’. That application was accompanied by the particulars and documents required under
Article 14(2) of Regulation (EC) No 1831/2003.
(4) The European Food Safety Authority (‘the Authority’) concluded in its opinion of 18 March 2025(3) that the
preparation of Saccharomyces cerevisiae NCYC R404 remains safe for dairy cows, consumers and the environment
under the conditions of use currently authorised. It also concluded that the preparation of Saccharomyces cerevisiae
NCYC R404, is not irritant to skin or eyes, and it should be considered a potential skin and respiratory sensitiser, and
any exposure through skin and respiratory tract is considered a risk. The Authority stated that the application for
renewal of the authorisation does not include a proposal for amending or supplementing the conditions of the
original authorisation that would have an impact on the efficacy of the additives. Therefore, it concluded that there is
no need for assessing the efficacy of the additives in the context of the renewal of the authorisation. 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 the assessment carried out regarding the method of analysis of the preparation of
Saccharomyces cerevisiae NCYC R404 as a feed additive in the context of the previous authorisations are valid and
applicable for the current application. In accordance with Article 5(4), point (c), of Commission Regulation (EC)
No 378/2005(4), an evaluation report of the Reference Laboratory is 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 Saccharomyces cerevisiaeNCYC R404 satisfies
the conditions provided for in Article 5 of Regulation (EC) No 1831/2003. Accordingly, the authorisation of that
additive should be renewed. 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. Those protective measures should be
without prejudice to other workers’ safety requirements under Union law.
(7) As a consequence of the renewal of the authorisation of the preparation of Saccharomyces cerevisiaeNCYC R404 as a
feed additive, Implementing Regulation (EU) 2015/502 should be repealed.
(8) 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:
Article 1
Renewal of the authorisation
The authorisation of the preparation specified in the Annex, belonging to the additive category ‘zootechnical additives’ and
to the functional group ‘gut flora stabilisers’, is renewed subject to the conditions laid down in that Annex.
Article 2
Repeal
Implementing Regulation (EU) 2015/502 is repealed.
Article 3
Entry into force
This Regulation shall enter into force on the twentieth day following that of its publication in the Official Journal of the
European Union.
