欧盟食品安全局评估一种地衣芽孢杆菌作为青贮饲料添加剂的安全性和有效性2019年8月8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）研究小组就地衣芽孢杆菌DSM 32457作为青贮饲料添加剂的安全性和有效性发表科学意见。
　　经过评估，FEEDAP小组得出结论认为，此种添加剂对目标物种、饲喂动物人员和环境是安全的。由于缺乏数据，其有效性无法确定。
　　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 Bacillus licheniformis DSM 32457 as a silage additive for all animal species. Bacillus licheniformis DSM 32457 is presumed safe for the target species, consumers of products from animals fed treated silage 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 skin sensitiser. Given the proteinaceous nature of the active agent, the additive should be considered a potential respiratory sensitiser. In the absence of appropriate data, the FEEDAP Panel cannot conclude on the efficacy of Bacillus licheniformis DSM 32457 as a silage additive.
