通過評定，權威專家工作組下結論，該添加物在7500 mg/kg全票價精飼料的較大提議應用水準下對貓是安全可靠的。在最少提議應用情況下（1500 mg/kg全票價精飼料），該添加物做為聚磷酸鹽黏合劑對成年人貓是合理的。一部分全文報導如下所示：

　　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).
