2021年4月28日，据欧盟食品安全局（EFSA）消息，应欧盟委员会要求，欧盟动物饲料添加剂和产品（FEEDAP）研究小组就乙二胺铜螯合物（copper chelate of ethylenediamine ）作为所有动物饲料添加剂的安全性和有效性。
经过评估，专家小组得出结论，该添加剂对育肥鸡和产蛋鸡是安全的，但不能对其他动物物种的安全性做出结论。也不能就添加剂对消费者或环境的安全性做出结论。但添加剂在提供铜以满足所有动物物种对这种微量元素的营养需求方面是有效的。部分原文报道如下：
Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of copper chelate of ethylenediamine (Copper‐EDA‐Cl) as a feed additive for all animal species. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP Panel) identified several issues related to the data provided concerning the chemical characteristics of the additive and, based on the information provided from an in vitro dissociation study, considered it unlikely that the additive consists only of copper mono‐chelate of EDA but of several coexisting (copper) species. Therefore, in the absence of adequate experimental data and owing to the uncertainties identified, the Panel cannot conclude on its identity and characterisation of the additive. The FEEDAP Panel concludes that the additive is safe for chickens for fattening and reared for laying/breeding but cannot conclude on the safety for other animal species/categories. The FEEDAP Panel cannot conclude on the safety of the additive for the consumer or the environment. The FEEDAP Panel concludes that handling the additive poses a risk to users by inhalation. The additive should be considered as non‐irritant for the skin but corrosive for the eyes and a skin sensitiser. The Panel notes the uncertainties on the genotoxicity potential of the additive that might have an impact on the conclusions on the safety for the user. The FEEDAP Panel concludes that the additive is efficacious in providing copper to meet the nutritional requirements of this trace element in all animal species.
