COMMI SSION IMPLEMENTING REGUL ATION (EU) 2019/804 
of 17 May 2019 
concer ning the renewal of the author isation of organic form of selenium produced by 
Sacc haromy ces cerevisiae CNCM I-3060 and of selenomethionine produced by Sacchar omy ces 
cerevisiae NCY C R397 as feed additiv es for all animal species and repealing Regulations (EC) 
No 1750/2006 and (EC) No 634/2007 
(Text with EEA relevance) 
THE EUR OPEAN COMMISSION, 
Having regar d to the Treaty on the Functioning of the European Union, 
Having regar d to Regulation (EC) No 1831/2003 of the European Parliament and of the Council of 22 September 2003 
on additives for use in animal nutr ition (1), and in particular Article 9(2) thereof, 
Whereas: 
(1)  Regulation (EC) No 1831/2003 provi des for the author isation of additives for use in animal nutr ition and for the 
grounds and procedures for granting and renewing such author isation. 
(2)  The orga nic form of selenium produced by Sacchar omyces cerevisiae CNCM I-3060 was author ised for 10 years as 
a feed additive for all animal species by Commission Regulation (EC) No 1750/2006 (2). Selenomethionine 
produced by Saccharomy ces cerevisiae NCY C R397 was author ised for 10 years as a feed additive for all animal 
species by Commission Regulation (EC) No 634/2007 (3). 
(3)  In accordance with Article 14 of Regulation (EC) No 1831/2003, applications were submitted for the renewal of 
the author isation of the organic form of selenium produced by Saccharomy ces cerevisiae CNCM I-3060 and of 
selenomethionine produced by Saccharomy ces cerevisiae NCY C R397 as feed additives for all animal species, 
requesting those additives to be classif ied in the additive catego ry ‘nutr itional additives ’. Those applications were 
accompan ied by the particulars and documents required under Article 14(2) of Regulation (EC) No 1831/2003. 
(4)  The European Food Safet y Author ity (‘the Author ity’) concluded in its opinions of 5 July 2018 (4) and 
28 November 2018 (5) that the applicants have provid ed data demonstrating that the additives compl y with the 
conditions of author isation under the proposed conditions of use. The Author ity confir med its previous 
conclusions that the organic form of selenium produced by Sacchar omyces cerevisiae CNCM I-3060 and the seleno ­
methionine produced by Saccharomy ces cerevisiae NCY C R397 do not have adverse effects on animal health, 
consumer safety or the envi ronment. It also state d for the organic form of selenium produced by Saccharom yces 
cerevisiae CNCM I-3060 capacities to be a respirator y sensitizer and hazardous upon inhalation, and for seleno ­
methionine produced by Saccharomy ces cerevisiae NCY C R397 capacities to be an eye and mucosae irritant, and 
a skin and respirato ry sensitizer . Theref ore, the Commission considers that appropr iate protective measures 
should be taken to prevent adverse effects on human health, in particular as regar ds the users of the additive. 
Finally , the Auth ority recommends changing the denomination of the additives. 
(5)  It is appropr iate to updat e the methods of analysis for selenium and selenomethionine based on the respective 
recent repor ts of the Reference Laboratory set up by Regulation (EC) No 1831/2003. 
(6) The assessment of the organic form of selenium produced by Saccharom yces cerevisiae CNCM I-3060 and of seleno ­
methionine produced by Saccharom yces cerevisiae NCY C R397 shows that the conditions for author isation, as 
provid ed for in Article 5 of Regulation (EC) No 1831/2003, are satisfied. According ly, the author isation of those 
additives should be renewed as specifi ed in the Annex to this Regulation. 20.5.2019 L 132/28 Official Jour nal of the European Union EN     
(1)OJ L 268, 18.10.2003, p. 29. 
(2)Commission Regulation (EC) No 1750/2006 of 27 November 2006 concer ning the author isation of selenomethionine as a feed additive 
(OJ L 330, 28.11.2006, p. 9). 
(3)Commission Regulation (EC) No 634/2007 of 7 June 2007 concer ning the author isation of selenomethionine produced by Saccharomy ces 
cerevisiae NCY C R397 as a feed additive (OJ L 146, 8.6.2007, p. 14). 
(4)EFSA Jour nal 2018;16(7):5386. 
(5)EFSA Jour nal 2019;17(1):5539. (7)  As a consequence of the renewal of the author isations of the organic form of selenium produced by Saccharom yces 
cerevisiae CNCM I-3060 and of selenomethionine produced by Sacchar omyces cerevisiae NCY C R397 as feed 
additives under the conditions laid down in the Annex to this Regulation, Regulations (EC) No 1750/2006 and 
(EC) No 634/2007 should be repealed. 
(8) Since safety reasons do not require the immediate application of the modifi cations to the conditions of author isa­
tion for the organic form of selenium produced by Saccharom yces cerevisiae CNCM I-3060 and for seleno ­
methionine produced by Saccharomy ces cerevisiae NCY C R397, it is appropr iate to allow a transitional period for 
inter ested parties to prepare themselves to meet the new requirements resulting from the renewal of the 
author isation. 
(9)  The measures provi ded for in this Regulation are in accordance with the opinion of the Standing Committee on 
Plants, Animals, Food and Feed, 
HAS ADOPTED THIS REGUL ATION: 
Article 1 
The author isation of the additives specifi ed in the Annex, belonging to the additive categor y ‘nutr itional additives’ and to 
the functional group ‘compounds of trace elements’, is renewed subject to the conditions laid down in that Annex. 
Article 2 
1. The organic form of selenium produced by Saccharom yces cerevisiae CNCM I-3060, selenomethionine produced by 
Saccharom yces cerevisiae NCY C R397 and premixtures containing these substances, which are produced and labelled before 
9 December 2019 in accordance with the rules applicable before 9 June 2019 may continue to be placed on the mark et

2. Feed mater ials and compo und feed containing the substances refer red to in point 1, whic h are produced and

the mark et and used until the existing stoc ks are exhaust ed if they are intended for food-producing animals. 
3. Feed mater ials and compo und feed containing the substances refer red to in point 1, whic h are produced and 
labelled before 9 June 2021 in accordance with the rules applicable before 9 June 2019 may continue to be placed on
