2022年2月25日，应欧盟委员会要求，欧盟动物饲料添加剂和产品（FEEDAP）研究小组就贝莱斯芽孢杆菌（Bacillus velezensis）NITE BP-01844作为育肥鸡、饲养产蛋鸡、育肥火鸡、饲养繁殖火鸡和所有育肥禽类或饲养至屠宰或产蛋点（包括非食品生产物种）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、使用该添加剂的动物产品的消费者和环境是安全的，但无法就添加剂对目标物种的功效作出结论。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 BA-KING? Bacillus velezensis when used as a feed additive for chickens for fattening, turkeys for fattening, chickens reared for laying, turkeys reared for breeding and all avian species for fattening, or rearing to slaughter or point of lay including non-food producing species. The product under assessment is based on viable spores of a strain identified as B.?velezensis, which is considered suitable for the qualified presumption of safety (QPS) approach to safety assessment. The identity of the active agent was established, and it does not harbour acquired antimicrobial resistance genes, lacks toxigenic potential and does not have the capacity to produce aminoglycosides. Following the QPS approach to safety assessment, B. velezensis NITE BP-01844 is presumed safe for the target species, consumers of products derived from animals fed the additive and the environment. Since no concerns are expected from the other components of the additive, BA-KING? is also considered safe for the target species, consumers of products derived from animals fed the additive and the environment. BA-KING? is not irritant to skin but is potentially irritant to eyes. In addition, should be considered a skin and respiratory sensitiser. The Panel is not in the position to conclude on the efficacy of BA-KING? for the target species.
