Abstract

The additive ‘Zinc chelate of methionine sulfate’ is zinc chelated with methionine in a molar ratio 1:1, with a minimum zinc content of 19.1%. Owing to the limitations of the tolerance study, it could not be used for the assessment of safety for target animals; therefore, the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP Panel) cannot conclude on the safety of zinc chelate of methionine sulfate for the target species. No concerns for consumer safety are expected from the use of the zinc chelate of methionine sulfate in animal nutrition when used up to the maximum EU authorised zinc levels in feed. Zinc chelate of methionine sulfate should be considered as a skin and eye irritant, and as a skin sensitiser; it is considered to pose a risk by inhalation to the users. The additive under assessment, zinc chelate of methionine sulfate, is intended to be a substitute for other authorised zinc additives and will not further increase the environmental burden of zinc; therefore, the FEEDAP Panel considers that the use of the additive in animal nutrition would not pose an additional risk for the environment. Based on literature studies and a specific study conducted with the additive under assessment, zinc chelate of methionine sulfate is an available source of zinc for all animal species.
