2019年12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）研究小组就一种L-蛋氨酸（L-Methionine） 作为所有动物物种的饲料和饮用水添加剂的安全性和有效性发表科学意见。
据了解，此种L-蛋氨酸是由谷氨酸棒杆菌（Corynebacterium glutamicum） KCCM 80184菌株和大肠杆菌（Escherichia coli） KCCM 80096菌株发酵产生的。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。部分原文报道如下：
The European Commission asked EFSA for an opinion on the safety for the target animals, consumer, user and the environment and on the efficacy of l‐methionine produced by fermentation with Corynebacterium glutamicum KCCM 80184 and Escherichia coli KCCM 80096 for all animal species. The two producing microorganisms were obtained by genetic modification. l‐Methionine is intended to be used in feed or water for drinking for all animal species and categories. Neither viable cells of the production strains, nor their recombinant DNA were detected in the final product. The additive does not pose any safety concern associated with the genetic modification of the production strains. l‐methionine produced by C. glutamicum KCCM 80184 and E. coli KCCM 80096. The additive is considered safe for the target species, for the consumer and for the environment. l‐Methionine produced by C. glutamicum KCCM 80184 and E. coli KCCM 80096 is considered not toxic by inhalation, non‐irritant to skin or eyes and not a dermal sensitiser. Regarding the use in water, the FEEDAP Panel reiterates its concerns over the safety of l‐methionine for target species when administered via water for drinking owing to the risk of nutritional imbalances and hygienic reasons. l‐Methionine produced by C. glutamicum KCCM 80184 and E. coli KCCM 80096 is considered as an efficacious source of the essential amino acid l‐methionine for non‐ruminant animal species. For the supplemental l‐methionine to be as efficacious in ruminants as in non‐ruminant species, it would require protection against degradation in the rumen.
