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 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 lanthanide citrate. 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 the preparation of lanthanide citrate as a feed additive for weaned 
piglets to be classified in the additive cate gory ‘zoote chnical additives ’. 
(4) The European Food Safety Author ity (‘the Author ity’) concluded in its opinions of 16 Apr il 2013 (2), 
20 Apr il 2016 (3) and 12 November 2019 (4) that, under the proposed conditions of use, the preparation of 
lanthanide citrate does not have an adverse effect on animal health, consumer safety or the environment. It also 
concluded that although the acute respirato ry toxicity data indicate that the dust is of low toxicity , prolonged or 
repeated exposure to the additive should be avoided. Theref ore, the Commission considers that appropr iate 
prote ctive measures should be taken to prevent adverse effects on human health, in particular as regar ds the users 
of the additive. The Auth ority also concluded that the additive has the potential to be efficacious in impro ving the 
growth of weaned piglets. The Author ity did not consider that there is a need for specifi c requirements of post- 
mark et monitoring. It also verified the repor t on the method of analysis of the feed additive in feed submitted by the 
Reference Laboratory set up by Regulation (EC) No 1831/2003. 
(5) The assessment of the preparation of lanthanide citrate shows that the conditions for author isation, as provided for 
in Article 5 of Regulation (EC) No 1831/2003, are satisfied. According ly, the use of that preparation should be 
author ised as specif ied in the Annex to this Regulation. 
(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, 
HAS ADOPTED THIS REGUL ATION: 
Article 1 
The preparation specified in the Annex, belonging to the additive categor y ‘zoot echnical additives ’ and to the functional 
group ‘other zootec hnical additives ’, is author ised as an additive in animal nutr ition, subject to the conditions laid down in 
that Annex.
