　 　食品伙伴网讯2021�?�?9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CCTCC M 2015595生产的L-赖氨酸盐酸盐� L-赖氨酸硫酸盐（l‐lysine mo nohydrochloride and l‐lysine sulfate）作为所有动物饲料添加剂的安全性发表科学意见�

　　经过评估，专家小组认为该添加剂对目标物种、消费者和环境都是安全的。没有为用户提供有关添加剂安全性的其他数据。因此，专家小组的结论仍然是，在没有数据的情况下，无法得出有关添加剂对使用者安全性的结论。部分原文报道如下：

　　Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety of l‐lysine mo nohydrochloride and l‐lysine sulfate produced using Corynebacterium glutamicum CCTCC M 2015595 for all animal species. In 2019, the FEEDAP Panel issued an opinion on the safety and efficacy of the products. In that assessment, the Panel could not co nclude on the safety of the additives for the target species, the co nsumers and the enviro nment due to the uncertainties regarding the possible genetic modification of the strain used to obtain the production strain C. glutamicum CCTCC M 2015595 and on the possible presence of viable cells and DNA of the production strain in the final products. Moreover, in the absence of data, the FEEDAP Panel could not co nclude on the safety of the additives for the users. The applicant provided supplementary data to characterise the strain from which the production strain under assessment was obtained. However, uncertainties remain on its origin and history of modification, including whether it has been genetically modified. The production strain C. glutamicum CCTCC M 2015595 did not show the presence of acquired antimicrobial resistance genes nor of toxin and virulence factors genes. Moreover, as viable cells and DNA of the production strain were not detected in both final formulations, l‐lysine HCl and l‐lysine sulfate do not raise safety co ncerns as regards the production strain. The FEEDAP Panel co ncluded that l‐lysine HCl and l‐lysine sulfate produced by C. glutamicum CCTCC M 2015595 are safe for the target species, co nsumers and for the environment. No additio nal data have been provided on the safety of the additives for users. Therefore, the co nclusions from the Panel remained that in the absence of data, no co nclusions on the safety of the additives for the user can be drawn.
