COMMISSION IMPLEMENTING REGUL ATION (EU) 2024/1068 
of 12 Apr il 2024
concer ning the author isation of a preparation of rosemar y extract as a feed additiv e for cats and dogs 
(Text with EEA relevance) 
THE EUR OPEAN COMMISSION,
Havi ng regar d to the Treaty on the Functioning of the European Union,
Havi ng rega rd to Regulation (EC) No 1831/2003 of the European Parliament and of the Council of 22 Sept ember 2003 on 
additives for use in animal nutr ition (1), and in particular Article 9(2) thereof,
Whereas:
(1) Regulation (EC) No 1831/2003 provid es for the author isation of additives for use in animal nutr ition and for the 
grounds and procedures for granting such an author isation.
(2) In accordance with Article 7 of Regulation (EC) No 1831/2003, an application was submitted for the author isation 
of a preparation of rosemar y extract obtained from dried leav es of Rosmar inus officinalis L., by acetone or ethanol 
extraction. That application was accompanied by the particulars and documents required under Article 7(3) of 
Regulation (EC) No 1831/2003.
(3) The application concer ns the author isation of a preparation of rosemar y extract as a feed additive for cats and dogs, 
requesting that additive to be classified in the cate gory ‘technological additives’ and in the functional group 
‘antio xidants’.
(4) The European Food Safety Author ity (‘the Author ity’) concluded in its opinion of 18 Novem ber 2021 (2)that, under 
the proposed conditions of use, the preparation of rosemar y extract obtained from dried leav es of Rosmar inus 
officinalis L., by acetone or ethanol extraction, is safe up to the maximum use levels of 300 mg/kg and 50 mg/kg 
compl ete feed for dogs and cats, respectively (that corresponds to a concentration of carnosic acid of 34 and 5 mg/ 
kg respectively). It also concluded that the preparation should be considered as irritant to skin and eyes, but it could 
not conclude on its pote ntial to be skin sensitiser . It considered that exposure through inhalation is unlikely . Since 
rosemar y extract is used as a food additive, and its function in feed would be essentially the same as that in food, the 
Authority concluded that no further demonstration of efficacy is considered necessar y. The Author ity also verified 
the repor t on the method of analysis of the feed additive in feed submitte d by the Reference Laborat ory set up by 
Regulation (EC) No 1831/2003.
(5) In view of the abov e, the Commission considers that the preparation of rosemar y extract satisfi es the conditions 
provid ed for in Article 5 of Regulation (EC) No 1831/2003. According ly, the use of that preparation should be 
author ised. In addition, the Commission considers that appropr iate protective measures should be taken to prevent 
adverse effects on the health of the users of the additive.
(6) The measures provid ed for in this Regulation are in accordance with the opinion of the Standing Committ ee on 
Plants, Animals, Food and Feed,

Article 1
The preparation specifi ed in the Annex, belonging to the additive catego ry ‘technological additives’ and to the functional 
group ‘antio xidants’, is author ised as an additive in animal nutr ition, subject to the conditions laid down in that Annex.
Article 2
This Regulation shall enter into force on the twentieth day followi ng that of its publication in the Official Journal of the 
European Union.
This Regulation shall be binding in its entirety and directly applicable in all Member States.
