Abstract

The EFSA FEEDAP Panel previously (2016) could not conclude on the safety of certain concentrated liquid l‐lysine (base), l‐lysine monohydrochloride (HCl) and l‐lysine sulfate products manufactured using different strains of Corynebacterium glutamicum. New information on the safety of these products was provided by the applicant. The recipient strain C. glutamicum KCTC 12307BP qualifies for qualified presumption of safety (QPS) approach for safety assessment, the genetic modification does not introduce any safety concern and no introduced antibiotic resistance genes remain in its genome. Even if uncertainty remains concerning the absence/presence of the production strain and/or its recombinant DNA in the final products, these would not raise safety concerns. The liquid l‐lysine (base) and l‐lysine HCl produced by C. glutamicum KCTC 12307BP or C. glutamicum KCCM 11117P; and l‐lysine HCl produced by C. glutamicum NRRL B‐50547 are considered safe for the target species, consumers and the environment. Regarding the safety for the user, concentrated liquid l‐lysine (base) and l‐lysine HCl produced by C. glutamicum KCTC 12307BP, C. glutamicum NRRL B‐50547 or C. glutamicum KCCM 11117P are not irritant to skin or eyes and they are not skin sensitisers. l‐Lysine HCl is not hazardous by inhalation. The use of C. glutamicum DSM 24990 in the production of l‐lysine sulfate is considered safe for the target species, consumers, users or the environment. No negative effects are to be expected for the target species within the proposed inclusion levels of 0.5–30 g lysine sulfate/kg complete feed provided that the total S intake complies with the recommendations of established scientific bodies. The use of C. glutamicum KCCM 10227 in the production of l‐lysine sulfate is considered safe for the target species, consumers, users and the environment with regard to antimicrobial resistance. No negative effects are to be expected for the target species within common inclusion levels provided that the total S intake complies with the recommendations of established scientific bodies.
