COMMISSION IMPLEMENTING REGUL ATION (EU) No 847/2014 
of 4 August 2014 
concer ning the author isation of DL-selenomethionine as a feed additiv e for all animal species 
(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 provides 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 isa­
tion of DL-selenomethionine. That application was accompanied by the particulars and documents required 
under Article 7(3) of Regulation (EC) No 1831/2003. 
(3)  That application concer ns the author isation of DL-selenomethionine, an organic compo und of selenium, as a 
feed additive for all animal species, to be classifie d in the additive catego ry ‘nutr itional additives ’. 
(4)  The European Food Safety Author ity (‘the Author ity’) concluded in its opinion of 30 Januar y 2014 (2) that, under 
the proposed conditions of use, DL-selenomethionine does not have an adverse effect on animal health, human 
health or the environment and that its use may be considered as an efficient source of selenium for all animal 
species. The Author ity does not consider that there is a need for specifi c requirements of post-market monitor ing. 
It also verified the repor t on the method of analysis of the feed additive in feed submitte d by the Reference 
Laboratory set up by Regulation (EC) No 1831/2003. 
(5)  The assessment of DL-selenomethionine 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 
specified in the Annex to this Regulation. 
(6)  The Author ity concluded that the limitation of the supplementation with organic selenium established for other 
organic compo unds of selenium should also apply to DL-selenomethionine. Further more, in case different 
compo unds of selenium are added to the feed, the supplementation with organic selenium should not excee d 
0,2 mg per kg compl ete feed. 
(7)  The measures provided 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 cate gory ‘nutr itional additives ’ and to the functional 
group ‘compounds of trace elements’, is author ised as an additive in animal nutr ition, subject to the conditions laid 
down in that Annex. 5.8.2014 L 232/10 Official Jour nal of the European Union EN

performa nce liquid chromat ography 
with UV detection (HPLC-UV). 
For the deter mination of tota l selenium 
in the feed additive: inductively coupled 
plasma mass spectrometr y (ICP -MS), or 
inductively coupled plasma atomi c emis ­
sion spectrometr y (ICP -AES). 
For the deter mination of tota l selenium
