2025年4月9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）研究小组就氧氯化铜（dicopper chloride trihydroxide）作为所有动物饲料添加剂的安全性发表科学意见。
经过评估，专家小组认为该添加剂对皮肤、眼睛和呼吸系统有刺激性，应被视为皮肤和呼吸致敏物质。任何暴露都被认为是一种风险。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 a scientific opinion on the safety of a feed additive consisting of dicopper chloride trihydroxide intended for use as a nutritional additive (functional group: compounds of trace elements) for all animal species. Regarding the safety for the user, in the previous assessment, the FEEDAP Panel concluded that the additive is hazardous by inhalation, it is irritant to skin and eye and a skin and respiratory sensitiser. For the current assessment, arguments have been provided by the applicant in support of the safety of the additive for the users exposed by inhalation. The FEEDAP Panel concluded that dicopper chloride trihydroxide is irritant to skin, eyes and the respiratory system and should be considered a skin and respiratory sensitiser. Any exposure is considered a risk.
