Scientific opinion on the safety and efficacy of iron compounds (E1) as feed additives for all species: iron chelate of amino acids, hydrate, based on a dossier submitted by Zinpro Animal Nutrition Inc.
2013
(FEEDAP), EFSA Panel on Additives and Products or Substances used in Animal Feed
The use of iron chelate of amino acids, hydrate, as source of iron is considered safe for all animal species/categories when used up to the currently authorised maximum content of total iron in complete feed, with the exception of bovines and poultry for which the maximum tolerated level is 450 mg/kg complete feed, and pets, for which the maximum tolerated level is 600 mg/kg complete feed. The FEEDAP Panel is not in the position to derive a maximum safe iron concentration in feed for horses or fish. Consumption surveys include iron-containing foodstuffs of animal origin. Since the supplementation of animal feed with iron-containing compounds has not essentially changed during the last decades, it is reasonable to assume that the iron levels in food of animal origin used in exposure scenarios originated from animals fed iron-supplemented diets. Since iron chelate of amino acids, hydrate, will be used as a substitute for other iron compounds, its use in animal nutrition would not modify consumer exposure to iron. The additive should be considered as a skin, eye and respiratory irritant and, owing to its residual peptide component, as a skin/respiratory sensitiser. Considering the high background concentration of iron in soil and water, the supplementation of feed with iron chelate of amino acids, hydrate, is not expected to pose an environmental risk. Iron chelate of amino acids, hydrate, is an effective source of iron for all animal species and categories. The FEEDAP Panel recommends that the maximum iron contents in complete feed be reduced as follows: bovines and poultry, 450 mg Fe/kg; and pets, 600 mg Fe/kg.
