2022年2月24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）研究小組就八水合碳酸鑭（lanthanum carbonate octahydrate）作為貓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 mg/kg全價飼料的最大建議使用水平下對貓是安全的。在最低建議使用條件下（1500 mg/kg全價飼料），該添加劑作為磷酸鹽粘合劑對成年貓是有效的。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 (Lanthan One) as a zootechnical feed additive for cats. The FEEDAP Panel concluded that lanthanum carbonate octahydrate is safe for cats at the maximum proposed use level of 7,500?mg/kg complete feed. The additive is not irritant to skin or eyes, is not a skin sensitiser and exposure of users by inhalation is considered unlikely. The Panel also concluded that the additive is efficacious as a phosphate binder in adult cats at the minimum proposed conditions of use (1,500?mg/kg complete feedingstuffs).
