2019年1月11日，歐盟食品安全局（EFSA）發(fā)布消息，應歐盟委員會要求，歐盟動物飼料添加劑和產品（FEEDAP）研究小組就羅伊氏乳桿菌NBF-2（DSM 32264）（Lactobacillus reuteri NBF-2（DSM 32264））作為貓飼料的安全性和有效性發(fā)表科學意見。

　　據了解，這種羅伊氏乳桿菌在貓飼料中使用的劑量為每只動物每天6×109 CFU。由于數據的缺乏，歐盟食品安全局動物飼料專家組（FEEDAP）無法斷定該添加劑對皮膚和眼睛有刺激性或是皮膚致敏的可能性，同時也無法得出羅伊乳酸桿菌NBF - 2對貓的功效。

　　部分原文報道如下：

　　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 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.
