Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of DSM 32651 when used as a technological additive to improve ensiling of fresh plant material. The additive is intended for use in all fresh 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 EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) 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 should be considered as a potential skin and respiratory sensitiser, and any exposure through skin and respiratory tract is considered a risk. The additive is not an eye irritant. The FEEDAP Panel concluded that the additive consisting of DSM 32651 at a minimum concentration of 1 × 10 CFU/kg fresh material may extend the aerobic stability of silage prepared from fresh plant material with a DM range of 28%-45%.
应欧盟委员会的要求，欧洲食品安全局（EFSA）被要求就DSM 32651用作技术添加剂以改善新鲜植物材料青贮效果的安全性和有效性提供科学意见。该添加剂拟用于所有动物物种的所有新鲜材料，建议最低浓度为1×10菌落形成单位（CFU）/千克新鲜植物材料。欧洲食品安全局认为该细菌物种适用于安全性评估的合格假定安全性方法。确定了该菌株的身份，未检测到令人担忧的获得性抗菌耐药基因。因此，欧洲食品安全局动物饲料添加剂和产品或物质专家小组（FEEDAP）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，该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。该添加剂不是眼部刺激物。FEEDAP专家小组得出结论，最低浓度为1×10 CFU/千克新鲜材料的由DSM 32651组成的添加剂可能会延长由干物质含量在28%-45%的新鲜植物材料制备的青贮饲料的有氧稳定性。
