Editorial context (read this before using the data point)
This is the EFSA FEEDAP jurisdiction on the nutrient/additive L-lysine monohydrochloride (C. glutamicum CGMCC 23982) — one of five nutrient-safety opinions in this final batch (Task L). Read with the efsa nutrient endpoints and AAFCO/FEDIAF provisions for the same nutrient.
Key findings (paraphrase; numbers and proper nouns verbatim from source)
- Production strain C. glutamicum CGMCC 23982 raises no safety concern.
- The additive is safe for the target species when supplemented in appropriate amounts and safe for consumers and the environment.
- User safety — a clear warning: L-lysine monohydrochloride is irritant to the skin, irritant to the eyes, and a respiratory irritant; exposure by any route is a risk.
- It is an effective source of L-lysine for all non-ruminant species; ruminants need protection from ruminal degradation.
Pet-food relevance
L-lysine is an essential amino acid, often first-limiting in cat and dog diets. This opinion (monohydrochloride salt) adds the explicit user-irritancy warning absent from the lysine-sulfate opinion; both safe-for-species conclusions hold.
