| Summary |
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.
In accordance with Article 7(1) of Regulation (EC) No 1831/2003, applications were submitted for the authorisation of liquid L-lysine base and technically pure L-lysine monohydrochloride as nutritional feed additives for use in feed and in water for drinking for all animal species. These applications were accompanied by the particulars and documents required under Article 7(3) of Regulation (EC) No 1831/2003.
The applications concern the authorisation of L-lysine base, liquid, and L-lysine monohydrochloride, technically pure, produced by Corynebacterium casei KCCM 80190 or Corynebacterium glutamicum KCCM 80216 or Corynebacterium glutamicum KCTC 12307BP as feed additives for all animal species to be classified in the additive category 'nutritional additives', functional group 'amino acids, their salts and analogues'.
The European Food Safety Authority ('the Authority') concluded in its opinions of 30 September 2020 and 18 November 2020 that, under the proposed conditions of use, L-lysine base, liquid, and L-lysine monohydrochloride, technically pure, produced by Corynebacterium casei KCCM 80190 or Corynebacterium glutamicum KCCM 80216 or Corynebacterium glutamicum KCTC 12307BP do not have an adverse effect on animal health, consumer health or the environment. The Authority could conclude on the safety for the user of the L-lysine base, liquid, and L-lysine monohydrochloride, technically pure, produced by Corynebacterium glutamicum KCCM 80216 and Corynebacterium glutamicum KCTC 12307BP. It stated that of L-lysine monohydrochloride, technically pure, and L-lysine base, liquid, produced by Corynebacterium casei KCCM 80190 are considered hazardous by inhalation and that L-lysine monohydrochloride, technically pure, produced by Corynebacterium casei KCCM 80190 is a mild eye irritant. Therefore, appropriate protective measures should be taken to prevent adverse effects on human health, in particular as regards the users of the additive. The Authority concluded that L-lysine base, liquid, and L-lysine monohydrochloride, technically pure, produced by Corynebacterium casei KCCM 80190 or Corynebacterium glutamicum KCCM 80216 or Corynebacterium glutamicum KCTC 12307BP, are effective sources of the essential amino acid L-lysine for all animal species. For the supplemental L-lysine to be fully efficacious in ruminants, it should be protected against degradation in the rumen. In its opinions, the Authority referred to a previous statement concerning potential nutritional imbalances for amino acids and hygienic concerns, when they are administered via water for drinking. However, the Authority did not propose a maximum content for the supplementation with L-lysine. 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-lysine as amino acid via water for drinking.
