　　经过评估，专家小组认为该添加剂对目标物种、消费者和环境都是安全的。评估中的添加剂被认为是氨基酸L-赖氨酸的有效来源。为了使补充的L-赖氨酸对反刍动物和非反刍动物同样有效，需要防止其在瘤胃中降解。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 l-lysine mo nohydrochloride (l-lysine HCl) and l-lysine sulfate produced by Corynebacterium glutamicum (C. glutamicum) CGMCC 14498 as a nutritio nal feed additive for all animal species. The active substance is l-lysine and it is produced in two different forms (mo nohydrochloride 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 co ncern associated with the production strain. l-Lysine HCl and l-lysine sulfate produced by C. glutamicum CGMCC 14498 are co nsidered safe for the target species. When using l-lysine sulfate, the background sulfur/sulfate co ntent 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 co nsumer and the environment. In the absence of data, the FEEDAP Panel cannot co nclude 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-mentio ned 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 co nsidered 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.
