2025年4月9日，據歐盟食品安全局（EFSA）消息，應歐盟委員會要求，歐盟動物飼料添加劑和產品（FEEDAP）研究小組就氧氯化銅（dicopper chloride trihydroxide）作為所有動物飼料添加劑的安全性發表科學意見。
經過評估，專家小組認為該添加劑對皮膚、眼睛和呼吸系統有刺激性，應被視為皮膚和呼吸致敏物質。任何暴露都被認為是一種風險。部分原文報道如下：
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.
