Editorial context (read this before using the data point)
This is the EFSA FEEDAP jurisdiction on the amino-acid feed additive C. glutamicum CCTCC M 20232577 — one of four amino-acid safety opinions in this batch. Read with the efsa nutrient endpoints and AAFCO/FEDIAF amino-acid provisions.
Key findings (paraphrase; numbers and proper nouns verbatim from source)
- The additive is considered safe for the target species when supplemented in appropriate amounts to the diet according to their nutritional needs (fermentation with *C. glutamicum* CCTCC M 20232577).
- The FEEDAP Panel has concerns on the use of L-arginine in water for drinking.
- Its use in animal nutrition is considered safe for consumers and for the environment.
- It is regarded as an effective source of the amino acid L-arginine for all non-ruminant species; to be as efficacious in ruminants as in non-ruminants it should be protected from ruminal degradation.
- On user safety, in the absence of data the Panel cannot conclude on the potential of the additive to be irritant to skin and/or eyes or to be a dermal sensitiser.
Pet-food relevance
L-arginine is a conditionally essential amino acid in cats, dogs and other pets. The explicit 'safe when supplemented to nutritional need' conclusion plus the drinking-water caveat are the usable formulator takeaways; the ruminant-protection note is relevant where pet diets include unprotected rumen-passage coatings.
Scope note / honest gap
