经过评估，专家小组认为该添加剂对目标物种、消费者和环境是安全的。评估中的添加剂被认为是所有非反刍动物物种氨基酸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 sulfate produced by fermentation using the genetically modified strain of Corynebacterium glutamicum, KCCM 80368, as a nutritional additive in feed for all animal species and categories. In the manufacturing process used to obtain the product under assessment, the cells from the production strain are inactivated but not removed from the final product. The FEEDAP Panel concluded that the additive does not give rise to any safety concern regarding the genetic modification of the strain. DNA from the strain is present in the final product, but its presence does not raise any safety issue since the strain does not harbour any gene of concern. No viable cells of the strain were detected in the final product. The use of l-lysine sulfate produced using C. glutamicum KCCM 80368 in feed is safe for the target species when supplemented in appropriate amounts to the diet according to the nutritional needs of the species. The use of the additive in animal nutrition is considered safe for the consumers of products from animals receiving the additive, and to the environment. With regard to the safety for the user, the additive is not irritant to the skin, but no conclusions could be reached on the eye irritation potential. The additive should be considered as a skin and respiratory sensitiser. Exposure by inhalation and dermal routes is considered a risk. The additive l-lysine sulfate produced using C. glutamicum KCCM 80368 is regarded as an effective source of the amino acid l-lysine for all non-ruminant species. To be as efficacious in ruminants as in non-ruminants, it should be protected from ruminal degradation.
