2019年1月11日，欧盟食品安全局（EFSA）发布消息，应欧盟委员会要求，欧盟动物饲料添加剂和产品（FEEDAP）研究小组就罗伊氏乳杆菌NBF-2（DSM 32264）（Lactobacillus reuteri NBF-2（DSM 32264））作为猫饲料的安全性和有效性发表科学意见。

  

　　据了解，这种罗伊氏乳杆菌在猫饲料中使用的最低剂量为每只动物每天6×109 CFU。由于数据的缺乏，欧盟食品安全局动物饲料专家组（FEEDAP）无法断定该添加剂对皮肤和眼睛有刺激性或是皮肤致敏的可能性，同时也无法得出罗伊乳酸杆菌NBF - 2对猫的功效。

　　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 and efficacy of Lactobacillus reuteri NBF‐2 when used in feed for cats at a minimum dose of 6 × 109 colony forming units （CFU） per animal and day. The additive is a preparation of viable cells of L. reuteri DSM 32264. This species is considered by EFSA to be suitable for the qualified presumption of safety （QPS） approach establishing safety for the target species and the environment. The active agent fulfils the requirements of the QPS approach to the assessment of safety. Consequently, in the absence of concerns form other components of the additives, Lactobacillus reuteri NBF‐2 is presumed safe for the target animals and the environment. Lactobacillus reuteri NBF‐2 should be considered a potential respiratory sensitiser. In the absence of data, the FEEDAP Panel cannot conclude on the irritancy of the additive to skin and eyes or on its dermal sensitisation. The FEEDAP the Panel is not in the position to conclude on the efficacy of Lactobacillus reuteri NBF‐2 for cats.
