2025年4月3日，据欧盟食品安全局（EFSA）消息，应欧盟委员会要求，欧盟动物饲料添加剂和产品（FEEDAP）研究小组就谷氨酸棒杆菌CGMCC 7.453发酵生产的L-赖氨酸盐酸盐（l-lysine monohydrochloride）作为所有动物饲料添加剂的安全性和有效性发表科学意见。
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 monohydrochloride produced by fermentation with a genetically modified strain of Corynebacterium glutamicum (CGMCC 7.453) as nutritional feed additive for all animal species. Neither viable cells nor recombinant DNA of the production strain were detected in the final product. Therefore, the FEEDAP Panel concluded that the additive does not pose any safety concern regarding the production strain. The FEEDAP Panel concluded that the use of l-lysine HCl produced by fermentation with the strain C. glutamicum CGMCC 7.453 is safe for the target species when administered via feed. However, the FEEDAP Panel expressed concerns on the use of l-lysine HCl in water for drinking. The Panel concluded that the use of l-lysine HCl produced by fermentation with C. glutamicum CGMCC 7.453 in animal nutrition is considered safe for the consumers and for the environment. With regards user safety, the additive should be considered irritant to skin, eyes and the respiratory tract. Any exposure to the additive is a risk. l-Lysine HCl is considered as efficacious source 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, it would require protection against degradation in the rumen.
