Editorial context (read this before using the data point)
This is the EFSA FEEDAP jurisdiction on the amino-acid feed additive L-tyrosine — one of four amino-acid safety opinions in this batch (Task L). Read with the efsa nutrient endpoints and AAFCO/FEDIAF amino-acid provisions.
Key findings (paraphrase; numbers and proper nouns verbatim from source)
- This is a renewal-of-authorisation assessment of L-tyrosine.
- Its use in animal nutrition remains safe for target species, consumers and the environment.
- User safety: L-tyrosine is not irritant to skin or eyes, but the Panel cannot conclude on dermal-sensitiser potential; inhalation exposure of handlers is likely.
Pet-food relevance
L-tyrosine is a conditionally essential amino acid in cats and dogs (precURSOR for catecholamines/thyroid hormone). The confirmed 'remains safe' conclusion is the usable takeaway; the open dermal-sensitiser question is the residual uncertainty.
Scope note / honest gap
Paraphrase of an EFSA opinion; source XML licence tag was CC-BY-ND, so this topic quotes only data points verbatim and rewrites prose. Renewal opinion (efficacy not re-assessed); full statistics are not reproduced.
