Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of Zinc‐lysinate sulfate (Plexomin® L‐Zn) as a nutritional feed additive for all animal species and categories. The applicant has provided evidence that, in essence, the additives under assessment comply with the proposed specifications. The Panel on Additives and Products or Substances used in Animal Feed (FEEDAP Panel) Panel concludes that zinc‐lysinate sulfate in animal nutrition under the conditions of use proposed is safe for the target species and for the terrestrial and freshwater ecosystems. No conclusion can be drawn on its safety for the marine environment. In the absence of adequate data on zinc deposition, the FEEDAP Panel cannot conclude on the safety of the additive for the consumer. The additive is irritant to the skin and eyes and is a dermal and respiratory sensitiser. Exposure of users by any route is considered a risk and should be minimised. The Panel concludes that the additive is an efficacious source of zinc for all animal species.
