欧盟评估鼠李糖乳杆菌IMI 507023 作为所有动物饲料添加剂的安全性和有效性

 

　　经过评估，专家小组认为该菌株用作青贮饲料添加剂对目标物种、消费者和环境都是安全的。由于缺乏数据，专家组无法就鼠李糖乳杆菌IMI 507023可能成为皮肤/眼睛刺激物或皮肤敏化剂得出结论。部分原文报道如下：

 

　　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 Lacticaseibacillus rhamnosus (formerly Lactobacillus rhamnosus) IMI 507023 as a technological additive for all animal species. The additive is intended to improve the production of silage at a proposed application rate of 1 × 109 colony-forming units (CFU)/kg fresh material. The bacterial species L. rhamnosus is considered by EFSA to be suitable for the qualified presumption of safety approach. As the identity of the strain has been established and no acquired antimicrobial resistance determinants of concern were detected, the use of the strain as a silage additive is considered safe for livestock species, for consumers and for 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 additive at the proposed application rate of 1 × 109 CFU/kg fresh material has the potential to improve the fermentation of the silages from easy to moderately difficult to ensile forages.
