据欧盟食品安全局（EFSA）消息，6月6日欧盟食品安全局就铁黑、铁红、铁黄（iron oxide black, red and yellow）用于动物饲料的安全性与效能发布意见。
欧盟食品安全局表示，拟将氧化铁黑、铁红与铁黄按照500-1200mg/kg的用量用作饲料着色剂。目标动物的耐受限量数据并未提供。氧化铁黑、铁红与铁黄被摄取后，会随粪便排出不会被吸收。然而由于生理学与毒理学数据尤其是基因毒性数据缺失，不能得出氧化铁用于目标动物的安全性数据。在效能方面，欧盟专家组认为，氧化铁作为饲料着色剂非常有效。当作为饲料着色剂时，应考虑饲料中的铁限量问题。
部分原文报道如下：
Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed （FEEDAP） was asked to deliver an opinion on the safety and efficacy of iron oxide black, red and yellow （E 172） for all animal species. These iron oxides are currently approved for feed and food use.
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.
