2019年2月27日，據(jù)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(chǎn)品（FEEDAP）研究小組被要求就二水鉬酸鈉（sodium molybdate dihydrate）作為作為綿羊飼料添加劑的安全性和有效性發(fā)表科學意見。

經(jīng)過評估，F(xiàn)EEDAP小組得出的結論是，在綿羊全價飼料中銅與鉬的最佳比例為3 - 10，銅含量最高為15mg/Kg，2.5 mg total Mo/kg全價飼料對綿羊來說是安全的。銅與鉬的比例為3 - 10時，補充鉬被認為是有效的。

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 safety and efficacy of sodium molybdate dihydrate for sheep, based on a dossier submitted for the re‐evaluation of the additive. The additive is currently authorised in the EU for all animal species as 'Nutritional additive' - 'Compounds of trace elements‘。 Taking the optimal Cu:Mo ratio of 3-10, and the highest total copper level authorised in complete feeds for sheep （15 mg/kg）， the FEEDAP Panel concluded that 2.5 mg total Mo/kg complete feed is safe for sheep. Considering （i） a safe intake of 0.6 mg Mo/day, （ii） the estimate average intake figure from food in Europe （generally less than 100 μg/day）， （iii） the contribution of foods of animal origin to the total molybdenum intake （estimated to be up to 22 %）， and （iv） that molybdenum would not accumulate in edible tissues/products of sheep fed molybdenum supplemented diets up to the upper safe level, the FEEDAP Panel concluded that the use of sodium molybdate as a additive in sheep at 2.5 mg total Mo/kg complete feed is safe for consumers.
