2022年8月4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）研究小组就罗伊氏乳杆菌（Limosilactobacillus reuteri）DSM 32264作为猫饲料添加剂的安全性和有效性发表科学意见。
Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the efficacy of a product consisting of Limosilactobacillus reuteri (formerly Lactobacillus reuteri) DSM 32264 as a zootechnical additive for cats. The additive is a preparation of viable cells of L. reuteri DSM 32264 and it has not been previously authorised as a feed additive in the European Union. The additive is intended for use in complete feed for cats at a minimum inclusion level of 6 × 109 colony forming units (CFU) per animal and day. In a previous opinion, the FEEDAP Panel could not conclude on the efficacy of L. reuteri DSM 32264 for cats. The applicant has provided supplementary information to support the efficacy of the additive for cats. based on the data provided, the FEEDAP Panel concluded that L. reuteri DSM 32264 has the potential to improve faecal consistency by reducing the moisture content of stools from cats receiving the additive at 1 × 1010 CFU/kg feed. However, the Panel had some reservations on the effects in the moisture content, which if maintained overtime, might cast doubts on the benefits on the long-term use of the additive since it could lead to constipation.
