Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on DSM 34271 when used as a technological additive to improve ensiling of fresh plant material. The additive is intended for use in easy and moderately difficult to ensile fresh plant material for all animal species at a proposed minimum concentration of 1 × 10 colony forming units (CFU)/kg fresh plant material. The bacterial species is considered by EFSA to be suitable for the qualified presumption of safety approach to safety assessment. The identity of the strain was established and no acquired antimicrobial resistance genes of concern were detected. Therefore, the FEEDAP Panel concluded that the use of the strain as a silage additive is considered safe for all the animal species, for consumers of products from animals fed the treated silage and for the environment. Regarding user safety, the additive containing DSM 34271 should be considered as a potential skin and respiratory sensitiser, and any exposure through skin and respiratory tract is considered a risk. One preparation was shown not to be irritant to skin or eyes. However, the Panel cannot assess the irritation potential of other possible preparations. The FEEDAP Panel concluded that DSM 34271 has the potential to improve the fermentation of the silage prepared from fresh plant material with a DM range of 30%-35% at a minimum concentration of 1 × 10 CFU/kg fresh material.
应欧盟委员会的要求，欧洲食品安全局（EFSA）被要求就DSM 34271用作技术添加剂以改善新鲜植物材料青贮时提供一份科学意见。该添加剂拟用于所有动物物种的易于青贮和中等难度青贮的新鲜植物材料，建议最低浓度为1×10菌落形成单位（CFU）/千克新鲜植物材料。EFSA认为该细菌物种适用于安全评估的合格假定安全性方法。已确定该菌株的身份，未检测到令人担忧的获得性抗菌抗性基因。因此，饲料添加剂和动物产品添加剂专家小组得出结论，将该菌株用作青贮添加剂对所有动物物种、食用经处理青贮饲料的动物产品的消费者以及环境而言被认为是安全的。关于使用者安全，含有DSM 34271的添加剂应被视为潜在的皮肤和呼吸道致敏剂，通过皮肤和呼吸道的任何接触都被视为有风险。有一种制剂被证明对皮肤或眼睛无刺激性。然而，专家小组无法评估其他可能制剂的刺激潜力。饲料添加剂和动物产品添加剂专家小组得出结论，DSM 34271有潜力在最低浓度为1×10 CFU/千克新鲜材料的情况下改善由干物质含量在30%-35%的新鲜植物材料制备的青贮饲料的发酵。
