2022年4月13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）ATCC PTA-6737作为育肥火鸡、饲养繁殖火鸡、产蛋鸡、用于产蛋的小型家禽物种、仔猪(断奶)、断奶小型猪物种和母猪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。该小组重申了之前就添加剂用于目标物种时的功效得出的结论。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 Bacillus subtilis ATCC PTA-6737 (Bacillus subtilis PB6) when used as a feed additive for turkeys for fattening, turkeys reared for breeding, laying hens, minor poultry species for laying, piglets (weaned), weaned minor porcine species and sows. With this application, the company requested the modification of the current authorisations as regards the strain taxonomy from B. subtilis ATCC PTA-6737 to Bacillus velezensis ATCC PTA-6737. The FEEDAP Panel concluded that the active agent of B. subtilis PB6 should be taxonomically designated as B. velezensis ATCC PTA-6737. The Panel also concluded that Bacillus velezensis PB6 is presumed safe for the target species, consumers and the environment and is not a dermal/eye irritant or a skin sensitiser but should be considered a respiratory sensitiser. The Panel reiterated the previous conclusions reached on the efficacy of the additive when used with the target species.
