In accordance with Article 7(1) of Regulation (EC) No 1831/2003, an application was submitted for the authorisation of Allura Red AC. That application was accompanied by the particulars and documents required under Article 7(3) of Regulation (EC) No 1831/2003. The application concerns the authorisation of Allura Red AC as a feed additive for small non-food producing mammals and ornamental birds, to be classified in the category 'sensory additives' and in the functional group 'colourants'. The European Food Safety Authority ('the Authority') concluded in its opinion of 11 November 2021 that, under the proposed conditions of use, Allura Red AC does not have adverse effects on animal health, consumer safety or the environment. The Authority could not conclude on the efficacy of Allura Red AC when used in feed for small non-food producing mammals and ornamental birds, considering the wide variety of feeding stuffs used in complete and complementary feed for small non-food producing mammals and ornamental birds, and the uncertainty of which concentration of Allura Red AC would result in a visible effect. However, the Authority also stated that for this additive, which is authorised in food and, where the function for feed is the same as that for food, no further demonstration of efficacy might be necessary. The Authority also verified the report on the methods of analysis of the feed additive in feed submitted by the Reference Laboratory set up by Regulation (EC) No 1831/2003. Moreover, Allura red AC is already authorised in feed for cats and dogs by Commission Implementing Regulation (EU) 2020/197 and the Authority concluded, in its opinion of 24 April 2012, that Allura Red AC is effective in colouring a typical feed for dogs at a minimum dose of 50 mg/kg, which is similar to the minimum levels proposed by the Authority for this use in small non-food producing mammals and ornamental birds. In view of the above, the Commission therefore considers that there is sufficient evidence of the efficacy of this substance. The assessment of Allura Red AC shows that the conditions for authorisation, as provided for in Article 5 of Regulation (EC) No 1831/2003, are satisfied. Accordingly, the use of that substance should be authorised as specified in the Annex to this Regulation.
