of 19 Febr uary 2020 
concer ning the author isation of erythrosine as a feed additiv e for dogs and cats 
(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 author isation. Article 10(2) of Regulation (EC) No 1831/2003 provid es 
for the re-evaluation of additives author ised pursuant to Council Directive 70/524/EEC (2). 
(2) Erythrosine was author ised without a time limit in accordance with Directive 70/524/EEC as a feed additive for 
ornamental fish belonging to the group ‘colourants, including pigments’, under the heading ‘other colourants’. It 
was also author ised without a time limit as a feed additive for dogs and cats belonging to the group ‘colourants, 
including pigments’, under the heading ‘colour ing agents author ised for colour ing foodstuffs by Community rules’. 
The additive was subsequently entered in the Regist er of feed additives as an existing product, in accordance with 
Article 10(1)(b) of Regulation (EC) No 1831/2003. 
(3) In accordance with Article 10(2) of Regulation (EC) No 1831/2003 in conjunction with Article 7 thereof, an 
application was submitt ed for the re-evaluation of erythrosine as a feed additive for ornamental fish and for dogs 
and cats. The applicant requeste d the additive to be classif ied in the additive catego ry ‘sensor y additive’ and in the 
functional group ‘colourants’. In accordance with Article 7 of Regulation (EC) No 1831/2003, the applicant also 
requeste d the author isation of erythrosine as a feed additive for a new use in reptiles, to be classif ied in the additive 
catego ry ‘sensor y additive’ and in the functional group ‘colourants’. Latel y, the applicant withdrew the application 
for ornamental fish and for reptiles. The application was accompan ied by the particulars and documents required 
under Article 7(3) of Regulation (EC) No 1831/2003. 
(4) The European Food Safet y Auth ority (‘the Auth ority’) concluded in its opinions of 16 November 2011 (3), 
8 Sept ember 2015 (4) and 3 Apr il 2019 (5) that, under the proposed conditions of use, erythrosine does not have an 
adverse effect on animal health. It also concluded that dermat ological reactions, including photosensitivity , 
erythroder ma and desquamation have been attributed to erythrosine and that an exposure of the lowe r respirato ry 
tract is considered a hazard for the user of the additive. 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

In accordance with Commission Regulation (EC) No 429/2008 (6), phase I of the environmental risk 
assessment has determined that erythrosine, as an additive intended for non-f ood producing animals, is exem pted 
from further assessment due to the unlikelihood of a signif icant environmental effect, there being no scientifically- 
based evidence for concer n having been identified by the Authority in its abov e-mentioned opinions. The Author ity 
further concluded that the substance concer ned is effective in adding colour to feedingstuffs and in favourably 
affecting the colour of ornamental fish. 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 submitted by the Reference Laboratory set up by Regulation (EC) No 1831/2003. 
(5) The assessment of the erythrosine shows that the conditions for author isation, as provi ded for in Article 5 of 
Regulation (EC) No 1831/2003, are satisfied. According ly, the use of that additive should be author ised as specified 
in the Annex to this Regulation. 
(6) Since safet y reasons do not require the immediate application of the modifications to the conditions of author isation 
of the substance concer ned, it is appropr iate to allow a transitional period for interest ed parties to prepare 
themselves to meet the new requirements resulting from the author isation. 
(7) 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 substance specified in the Annex, belonging to the additive cate gory ‘sensor y additives’ and to the functional group
