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 an additive consisting of DSM 33189 and (formerly ) DSM 12856 as a technological additive for all animal species. The additive is intended to improve the production of silage at a proposed application rate of 1 × 10 colony-forming units (CFU)/kg fresh material. The bacterial species and are considered by EFSA to be suitable for the qualified presumption of safety (QPS) approach to assessment. As the identity of the strains has been clearly established and no acquired antimicrobial resistance determinants of concern were detected, the use of the strains as a silage additive is considered safe for livestock species, for consumers and for the environment. The additive is not irritant for eyes or skin but should be considered a respiratory sensitiser. In the absence of data, the FEEDAP Panel could not conclude on the potential of the additive to be a skin sensitiser. The additive at the proposed application rate of 1 × 10 CFU/kg fresh plant material showed the potential to improve the aerobic stability silage with dry matter content ranging from 30% to 70%.
应欧盟委员会的要求，动物饲料添加剂及产品或物质专家小组（FEEDAP）被要求就一种由DSM 33189和（原）DSM 12856组成的添加剂作为所有动物物种的技术添加剂的安全性和有效性发表科学意见。该添加剂旨在以1×10菌落形成单位（CFU）/千克新鲜物料的建议施用量提高青贮饲料的产量。欧洲食品安全局（EFSA）认为细菌物种和适合采用合格安全推定（QPS）评估方法。由于菌株的身份已明确确定，且未检测到令人担忧的获得性抗菌耐药性决定因素，因此将这些菌株用作青贮饲料添加剂被认为对牲畜物种、消费者和环境都是安全的。该添加剂对眼睛或皮肤无刺激性，但应被视为呼吸道致敏剂。由于缺乏数据，FEEDAP小组无法就该添加剂成为皮肤致敏剂的可能性得出结论。以1×10 CFU/千克新鲜植物物料的建议施用量使用该添加剂，显示出有潜力提高干物质含量在30%至70%之间的青贮饲料的有氧稳定性。
