通過評定，權威專家工作組覺得該添加物對總體目標外來物種、顧客和條件全是安全性的。評定中的添加物被覺得是碳水化合物L-磷酸氫鈣的合理來源于。為了更好地使填補的L-磷酸氫鈣對食草動物和非反芻動物一樣合理，必須控制其在瘤胃中溶解。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 l-lysine monohydrochloride (l-lysine HCl) and l-lysine sulfate produced by Corynebacterium glutamicum (C. glutamicum) CGMCC 14498 as a nutritional feed additive for all animal species. The active substance is l-lysine and it is produced in two different forms (monohydrochloride or sulfate). The production strain C. glutamicum CGMCC 14498 and its recombinant DNA were not detected in the final products. The products l-lysine HCl and l-lysine sulfate do not pose any safety concern associated with the production strain. l-Lysine HCl and l-lysine sulfate produced by C. glutamicum CGMCC 14498 are considered safe for the target species. When using l-lysine sulfate, the background sulfur/sulfate content in the compound feed should be taken into account. l-Lysine HCl and l-lysine sulfate produced by C. glutamicum CGMCC 14498 are safe for the consumer and the environment. In the absence of data, the FEEDAP Panel cannot conclude on the potential of l-lysine HCl produced by the strain C. glutamicum CGMCC 14498 to be toxic by inhalation, and on the potential of l-lysine HCl and l-lysine sulfate produced by the above-mentioned strain to be irritant to skin or eyes, or on their potential to be dermal sensitisers. l-Lysine HCl and l-lysine sulfate produced by C. glutamicum CGMCC 14498 are considered efficacious sources of the essential amino acid l-lysine for non-ruminant animal species. For the supplemental l-lysine to be as efficacious in ruminants as in non-ruminant species, this would require protection against degradation in the rumen.
