            COMMISSION IMPLEMENTING REGULATION (EU) 2020/378
of 5 March 2020
         
concerning the authorisation of L-leucine as a feed additive for all animal species
(Text with EEA relevance)


THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,


Having regard to Regulation (EC) No 1831/2003 of the European Parliament and of the Council of 22 September 2003 on additives for use in animal nutrition (1), and in particular Article 9(2) thereof,

Whereas:







(1)


Regulation (EC) No 1831/2003 provides for the authorisation of additives for use in animal nutrition and for the grounds and procedures for granting such authorisation.












(2)


In accordance with Article 7(1) of Regulation (EC) No 1831/2003, an application was submitted for the authorisation of L-leucine produced by Escherichia coli NITE BP-02351 as a nutritional feed additive for use in feed and in water for drinking and as sensory feed additive for use in feed for all animal species. This application was accompanied by the particulars and documents required under Article 7(3) of Regulation (EC) No 1831/2003.












(3)


This application concerns the authorisation of L-leucine produced by Escherichia coli NITE BP-02351 as a feed additive for all animal species to be classified in the additive category ‘nutritional additives’ (functional group ‘amino acids, their salts and analogues’) and in the additive category ‘sensory additives’ (functional group ‘flavouring compounds’).












(4)


The European Food Safety Authority (‘the Authority’) concluded in its opinion of 2 April 2019 (2) that, under the proposed conditions of use, L-leucine produced by Escherichia coli NITE BP-02351 does not have an adverse effect on animal health, consumer health or the environment. It also stated that L-leucine produced by Escherichia coli NITE BP-02351 could pose an inhalation risk for the users of the additive. Therefore, appropriate protective measures should be taken to prevent adverse effects on human health, in particular as regards the users of the additive.












(5)


The Authority concluded that it is an effective source of the amino acid L-leucine for all animal species. For the supplemental L-leucine to be fully efficacious in ruminants, it should be protected against degradation in the rumen. The Authority expressed in a previous statement a concern over potential nutritional imbalances for amino acids, when they are administered via water for drinking. However, the Authority did not propose a maximum content for L-leucine. Thus, it is appropriate to indicate on the label of the additive, and premixtures containing it, an alert to take into account the dietary supply with all the essential and conditionally essential amino acids, particularly in the case of supplementation with L-leucine as amino acid via water for drinking.












(6)


As regards the use of L-leucine as a flavouring, the Authority states that no further demonstration of efficacy is necessary when the substance is used at the recommended dose level. The use of L-leucine as a flavouring compound is not authorised in water for drinking. At the recommended dose, L-leucine as flavouring compound is not likely to pose any concern for the dietary supply with all the essential and conditionally essential amino acids.












(7)


The Authority does not consider that there is a need for specific requirements of post-market monitoring. It also verified the reports on the method of analysis of the feed additive in feed submitted by the Reference Laboratory set up by Regulation (EC) No 1831/2003.












(8)


The assessment of L-leucine shows that the conditions for authorisation, as provided for in Article 5 of Regulation (EC) No 1831/2003, are satisfied. Accordingly, the use of this additive should be authorised as specified in the Annex to this Regulation.












(9)


The fact that the use of the L-leucine is not authorised for use as a flavouring in water for drinking, does not preclude its use in compound feed, which is administered via water.












(10)


The measures provided for in this Regulation are in accordance with the opinion of the Standing Committee on Plants, Animals, Food and Feed,





HAS ADOPTED THIS REGULATION:



Article 1
L-leucine produced by Escherichia coli NITE BP-02351, specified in the Annex, is authorised as a feed additive in animal nutrition in the additive category ‘nutritional additives’, functional group ‘amino acids, their salts and analogues’, and in the additive category ‘sensory additives’, functional group ‘flavouring compounds’, subject to the conditions laid down in that Annex.


Article 2
This Regulation shall enter into force on the twentieth day following 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.
Done at Brussels, 5 March 2020.


For the Commission


The President

Ursula VON DER LEYEN
