通过评定，权威专家工作组下结论，该添加物在7500 mg/kg全票价精饲料的较大提议应用水准下对猫是安全可靠的。在最少提议应用情况下（1500 mg/kg全票价精饲料），该添加物做为聚磷酸盐黏合剂对成年人猫是合理的。一部分全文报导如下所示：

　　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).
