2024年4月10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）研究小組就碳酸鑭（lanthanum carbonate octahydrate）作為狗飼料添加劑的安全性和有效性發表科學意見。
經過評估，專家小組得出結論，該添加劑在7500毫克/千克全價飼料的最大推薦水平下對成年狗是安全的。該添加劑在1500毫克/千克全價飼料的最低含量水平下可有效降低成年犬的磷生物利用率。部分原文報道如下：
Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of lanthanum carbonate octahydrate as a zootechnical feed additive for dogs. The additive is already authorised for use in feed for cats. The FEEDAP Panel concluded that the additive lanthanum carbonate octahydrate is safe for adult dogs at the maximum recommended level of 7500 mg/kg complete feed. The additive is not irritant to skin or eyes, is not a skin sensitiser and exposure by inhalation is considered to be unlikely. The Panel also concluded that lanthanum carbonate octahydrate is efficacious in the reduction of phosphorus bioavailability in adult dogs at the minimum inclusion level of 1500 mg/kg complete feed.
