2024年11月7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）研究小组就枯草芽孢杆菌DSM 33862和布氏乳杆菌DSM 12856作为所有动物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，专家小组认为在建议的使用条件下该添加剂对动物物种、消费者和环境是安全的。部分原文报道如下：
Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on a formulation of Bacillus subtilis DSM 33862 and Lentilactobacillus buchneri DSM 12856 when used as a technological additive to improve ensiling of fresh plant material. The additive is intended for use with fresh plant material with a dry matter (DM) range of 32%–65% at a proposed minimum concentration of 1 × 108 colony forming units (CFU)/kg fresh plant material to be used for all animal species. The bacterial species B. subtilis and L. buchneri are considered by EFSA to be suitable for the qualified presumption of safety approach to safety assessment. The identity of the strains was established, no acquired antimicrobial resistance genes of concern were detected in any of the two active agents and no evidence of toxigenic potential was found in B. subtilis DSM 33862. Therefore, the FEEDAP Panel concluded that the use of the strains as a silage additive is considered safe for all the animal species, for consumers of products from animals fed with the treated silage and for the environment. Regarding user safety, the additive contains microorganisms and therefore should be considered as a potential skin and respiratory sensitiser. The additive is not irritant to skin or eyes. Inhalation and dermal exposure is considered a risk. These conclusions would apply, in principle, to any preparations containing the active agents. The FEEDAP Panel concluded that the additive containing B. subtilis DSM 33862 and L. buchneri DSM 12856 at a minimum concentration of 1 × 108 CFU/kg fresh material has the potential to extend the aerobic stability of silage prepared from fresh plant materials with a DM range of 32%–65%.
