    2023年6月12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）研究小组就布氏乳杆菌（Lentilactobacillus buchneri） DSM 32650作为所有动物饲料添加剂的安全性和有效性发表科学意见。

经过评估，专家小组认为在拟议的使用条件下，该添加剂对目标物种、消费者和环境是安全的。部分原文报道如下：

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of Lentilactobacillus buchneri DSM 32650 as a technological feed additive (functional group: silage additive) for all animal species. The additive is intended to improve the production of silage at a proposed application rate of 1 × 10⁸colony-forming units (CFU)/kg fresh material. The bacterial species L. buchneri is considered by the European Food Safety Authority to be suitable for the qualified presumption of safety (QPS) approach. As the identity of the strain has been established and no antimicrobial resistance determinants of concern were detected, the use of the strain as a silage additive is considered safe for the target species, consumers and the environment. In the absence of data, the FEEDAP Panel cannot conclude on the potential of the additive to be a skin/eye irritant or a skin sensitiser. Given the proteinaceous nature of the active agent, the additive should be considered a respiratory sensitiser. The FEEDAP Panel concluded that Lentilactobacillus buchneri DSM 32650 at a minimum concentration of 1 × 10⁸CFU/kg fresh material may extend the aerobic stability of silage from easy and moderately difficult to ensile fresh material with a dry matter content ranging from 28% to 45%.
