(5)In view of the above, the Commission considers that L-histidine and L-histidine monohydrochloride monohydrate, produced with Corynebacterium glutamicum KCCM 80389, satisfy the conditions provided for in Article 5 of Regulation (EC) No 1831/2003. Accordingly, the use of those substances as feed additives should be authorised. The Commission considers that the safe use of those additives in water for drinking, with regard to possible hygiene risks, is to be considered within the scope of Regulation (EC) No 183/2005 of the European Parliament and of the Councilnote laying down requirements for feed hygiene. When fed to ruminants for the use under the functional group ‘amino acids, their salts and analogues’, L-histidine and L-histidine monohydrochloride monohydrate, produced with Corynebacterium glutamicum KCCM 80389, need protection against degradation in the rumen. It is also 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-histidine and L-histidine monohydrochloride monohydrate via water for drinking.
