(2) A preparation of diclazuril (Clinacox 0,5 %) (‘the preparation’) was authorised for a period of 10 years as a feed additive for chickens for fattening by Commission Regulation (EU) No 1118/2010 (2) and for chickens reared for laying by Commission Implementing Regulation (EU) No 667/2013 (3). (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 as a feed additive for chickens for fattening and chickens reared for laying. The application requested that additive to be classified in the category ‘coccidiostats and histomonostats’. 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 opinions of 27 June 2024 (4) and 28 January 2026 (5) that the applicant has provided evidence that the preparation remains safe for the target species, as well as for the consumers and the environment at a maximum use level of 1 mg diclazuril/kg complete feed. It also concluded that the preparation is irritant to skin, eyes and the respiratory tract but is not a skin sensitiser. The Authority further concluded that the preparation at a concentration of 1 mg diclazuril/kg complete feed has the potential to control coccidiosis in chickens for fattening and extended that conclusion to chickens reared for laying. It considered that there is a need for specific requirements of post-market monitoring, recommending that the development of resistance to diclazuril of field Eimeria spp. strains isolated from chickens be monitored. (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 as a feed additive in the context of the previous authorisation are valid and applicable for the current application. In accordance with Article 5(4), point (c), of Commission Regulation (EC) No 378/2005 (6), an evaluation report of the Reference Laboratory is therefore not required. (6) In view of the above, the Commission considers that the preparation 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. (7) As a consequence of the renewal of the authorisation of the preparation as a feed additive, Regulation (EU) No 1118/2010 and Implementing Regulation (EU) No 667/2013 should be repealed. (8) Since safety reasons do not require the immediate application of the modifications to the conditions of authorisation of the preparation, it is appropriate to provide for a transitional period for interested parties to prepare themselves to meet the new requirements resulting from the renewal of the authorisation. (9) 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 authorisation {#art_1} The authorisation of the preparation specified in the Annex, belonging to the additive category ‘coccidiostats and histomonostats’ is renewed subject to the conditions laid down in that Annex. ## Article 2 Repeal {#art_2} Regulation (EU) No 1118/2010 and Implementing Regulation (EU) No 667/2013 are repealed. ## Article 3 Transitional measures {#art_3} 1.   The preparation, as authorised by Regulation (EU) No 1118/2010 and Implementing Regulation (EU) No 667/2013 and premixtures containing that additive, which are produced and labelled before 11 April 2027 in accordance with the rules applicable before 11 October 2026 may continue to be placed on the market and used until the stocks concerned are exhausted. 2.   Compound feed and feed materials containing the feed additive referred to in paragraph 1, which are produced and labelled before 11 October 2027 in accordance with the rules applicable before 11 October 2026 may continue to be placed on the market and used until the stocks concerned are exhausted. ## Article 4 Entry into force {#art_4} This Regulation shall enter into force on the twentieth day following that of its publication in the Official Journal of the European Union. ## ANNEX {#anx_1} Identification number of the additive Name of the holder of authorisation Name of the additive (trade name) Composition, chemical formula, description, analytical method Species or category of animal Maximum age Minimum content Maximum content Other provisions End of period of authorisation Maximum residue limits (MRLs) in the relevant foodstuffs of animal origin mg of active substance/kg of complete feed with a moisture content of 12 % Category: coccidiostats and histomonostats 51771 Elanco GmbH Diclazuril 0,5 g/100 g (Clinacox 0,5 %) Additive composition Preparation of — Diclazuril: 5 g/kg — Polyvidone K30: 2 g/kg — Sodium hydroxide: 0,5 g/kg — Soybean meal q.s.
