Scientific Opinion on the safety and efficacy of copper chelate of L-lysinate-HCl as feed additive for all animal species
EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP)
Copper chelate of L-lysinate-HCl, provided as powder and as granulate, is intended for use as a copper source in animal nutrition. Tolerance studies with chicken for fattening and weaned piglets, allowed the FEEDAP Panel to conclude that copper chelate of L-lysinate-HCl is a safe source of copper for all animal species, provided that the maximum copper contents authorised in feed are respected. The supplementation of feeds with copper from copper chelate of L-lysinate-HCl up to the maximum authorised copper levels is not expected to result in a different copper deposition in edible tissues/products than the standard inorganic source cupric sulphate pentahydrate. No concerns for consumer safety will arise from the use of the additive in animal nutrition, provided that the maximum copper contents authorised in feed are respected. The powder form of copper chelate of L-lysinate-HCl should be considered as a risk by inhalation; exposure by inhalation should be minimised. Neither form of the additive is a dermal irritant but the powder form is an eye irritant. In the absence of data, it is considered prudent to regard both forms as potential skin sensitisers. Copper chelate of L-lysinate-HCl is intended to be a substitute for other authorised copper additives; it will therefore not further increase the environmental burden from copper. Copper chelate of L-lysinate-HCl is an efficacious source of copper in meeting animal requirements. The Panel made some recommendations regarding the Description and Conditions of use of the additive and the maximum residue limits established for copper in animal tissues and products.
