2022年2月24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）研究小组就八水合碳酸镧（lanthanum carbonate octahydrate）作为猫饲料添加剂的安全性和有效性发表科学意见。
经过评估，专家小组得出结论，该添加剂在7500 mg/kg全价饲料的最大建议使用水平下对猫是安全的。在最低建议使用条件下（1500 mg/kg全价饲料），该添加剂作为磷酸盐粘合剂对成年猫是有效的。部分原文报道如下：
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).
