(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 an authorisation. 

(2) In accordance with Article 7 of Regulation (EC) No 1831/2003, an application was submitted for the authorisation of L-threonine produced with Escherichia coli CGMCC 7.455. That application was accompanied by the particulars and documents required under Article 7(3) of Regulation (EC) No 1831/2003. 

(3) The application concerns the authorisation of L-threonine produced with Escherichia coli CGMCC 7.455 as a feed additive for use in feed and in water for drinking for all animal species, requesting that additive to be classified in the category ‘nutritional additives’ and in the functional group ‘amino acids, their salts and analogues’. 

(4) The European Food Safety Authority (‘the Authority’) concluded in its opinion of 12 March 2024 that, under the proposed conditions of use, L-threonine produced with Escherichia coli CGMCC 7.455 is safe for the target species. However, the Authority has concerns on the safety of the substance for the target species resulting from the simultaneous administration of L-threonine via water for drinking and feed due to possible amino acid imbalances and hygienic reasons. The use of L-threonine produced with E. coli CGMCC 7.455 in animal nutrition is considered safe for the consumers and for the environment. In the absence of data, the Authority could not conclude on the potential of the additive to be irritant to skin or eyes, or on its potential to be a dermal sensitiser. Regarding the endotoxin activity in the additive the Authority concluded that it does not pose a risk for the user via inhalation. The Authority further concluded that the substance is regarded as an efficacious source of the essential amino acid L-threonine for non-ruminant species and that for the substance to be fully efficacious in ruminants, it should be protected against degradation in the rumen. The Authority did not consider that there is a need for specific requirements of post-market monitoring. It also verified the report 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) In view of the above, the Commission considers that L-threonine produced with Escherichia coli CGMCC 7.455 satisfies the conditions provided for in Article 5 of Regulation (EC) No 1831/2003. Accordingly, the use of that substance as a feed additive should be authorised. When fed to ruminants, L-threonine needs to be protected against degradation in the rumen. It is appropriate to alert the user to take into account the dietary supply with all the essential and conditionally essential amino acids, in particular in the case of supplementation with L-threonine via water for drinking. In addition, the Commission considers that appropriate protective measures should be taken to prevent adverse effects on the health of the users of the additive. 

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