欧盟评估枯草芽孢杆菌PB6菌株作为育肥鸡等家禽饲料添加剂的安全性和有效性2020年11月10日，应欧盟委员会要求，欧盟动物饲料添加剂和产品（FEEDAP）研究小组就枯草芽孢杆菌（Bacillus subtilis）PB6菌株作为育肥鸡、蛋鸡、小型家禽，观赏性、运动性和游戏性鸟类饲料添加剂的安全性和有效性发布科学意见。
　　经过评估，专家小组认为该添加剂对目标物种、消费者和环境是安全的。在FEEDAP小组先前进行的评估中，该添加剂在育肥鸡和蛋鸡的饲料中以1×107 CFU/kg的水平添加时被证明是一种有效的动物饲料添加剂。考虑到已经显示出相同水平的功效，这一结论可被外推至观赏性、运动性和游戏性鸟类。
　　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 renewal of the authorisation of Bacillus subtilisPB6, the extension of use to ornamental, sporting and game birds and a modification on the concentration of the said additive. The product under assessment is based on viable spores of a strain originally identified as Bacillus subtilis. During the course of the current assessment, the active agent has been redesignated as Bacillus velezensisATCC PTA‐6737. The bacterial species B. velezensis is considered suitable for the qualified presumption of safety (QPS) approach to safety assessment. The identity of the active agent is established and the compliance with the other qualifications /confirm/ied. Therefore, B. velezensisATCC PTA‐6737 is presumed safe for the target species, consumers of products derived from animals fed the additive and the environment. The additive is not a dermal/eye irritant or a skin sensitiser. Exposure via inhalation is unlikely. In the previous assessments performed by the FEEDAP Panel, the additive showed to be efficacious as a zootechnical additive in feedingstuffs for chickens for fattening and chickens reared for laying at the level of 1 × 107 CFU/kg. Considering that efficacy at the same level has been shown, this conclusion is extrapolated to ornamental, sporting and gaming birds.
