Iron oxides black, red and yellow are intended to be used as colourings to add and restore colour to feedingstuffs at a recommended concentration between 500 and 1,200 mg/kg. No data on the tolerance of target animals were provided. The iron oxides black, red and yellow are excreted essentially unchanged in the faeces of the target animals. Iron absorption from these water insoluble iron oxides is low. However, no conclusion on the safety of the iron oxides under assessment for the target animals could be made as a sufficient biological and toxicological database, particularly genotoxicity data, was not available. The use of the iron oxides in animal nutrition is unlikely to result in a direct exposure of the consumer and would not influence the iron content of edible tissues and products from animals treated with iron oxides. Consequently, the supplementation of feed for food-producing animals with the iron oxides under assessment would not provide a risk to consumers. Iron oxide black, red and yellow should be considered as irritant to skin and eyes. In the absence of any information, the Panel on Additives and Products or Substances used in Animal Feed FEEDAP cannot conclude on the potential of the additives to be a skin sensitiser. As the inhalation of iron oxides could cause unspecific lung inflammation, inhalation exposure of users should be considered to be a hazard. As there is concern about the possible genotoxicity of iron oxides, any route of exposure should be considered as hazardous. The use of iron oxide black, red and yellow in animal nutrition does not pose a risk to the environment. The iron oxides are effective in colouring feedingstuffs.
黑色、红色和黄色氧化铁拟用作着色剂,以推荐浓度500至1200毫克/千克添加到饲料中并恢复饲料颜色。未提供目标动物耐受性的数据。黑色、红色和黄色氧化铁在目标动物粪便中基本原样排出。从这些水不溶性氧化铁中的铁吸收很低。然而,由于没有足够的生物学和毒理学数据库,特别是遗传毒性数据,无法就所评估的氧化铁对目标动物的安全性得出结论。在动物营养中使用氧化铁不太可能导致消费者直接接触,并且不会影响用氧化铁处理的动物可食用组织和产品的铁含量。因此,用所评估的氧化铁补充产食用动物的饲料不会对消费者构成风险。黑色、红色和黄色氧化铁应被视为对皮肤和眼睛有刺激性。由于缺乏任何信息,动物饲料添加剂和产品或物质专家委员会(FEEDAP)无法就添加剂成为皮肤致敏剂的可能性得出结论。由于吸入氧化铁可能会引起非特异性肺部炎症,应认为使用者吸入接触具有危害性。由于担心氧化铁可能具有遗传毒性,任何接触途径都应被视为具有危害性。在动物营养中使用黑色、红色和黄色氧化铁对环境不构成风险。氧化铁在给饲料着色方面很有效。
