2020年7月21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）研究小组就类谷糠乳杆菌（Lactobacillus parafarraginis ）DSM 32962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，专家小组认为该添加剂对目标物种、消费者和环境是安全的。浓度为1×108 CFU/kg植物原料的类谷糠乳杆菌DSM 32962表现出显着改善干物质含量为30％至70％的牧草原料青贮饲料有氧稳定性的潜力。部分原文报道如下：
Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed was asked to deliver a scientific opinion on the safety and efficacy of Lactobacillus parafarraginis DSM 32962 when used as a technological additive intended to improve the production of silage at a proposed application rate of 1 × 108 colony forming units （CFU ）/kg fresh material. The bacterial species L. parafarraginis is considered by EFSA to be suitable for the qualified presumption of safety approach to safety assessment. As the identity of the strain has been clearly established and no acquired antimicrobial resistance determinants of concern were detected, the use of the strain as a silage additive is considered safe for livestock species, for consumers of products from animals fed the treated silage and for the environment. The additive is not an eye or dermal irritant but should be considered a potential respiratory sensitiser. No conclusions can be drawn on the skin sensitisation potential of the additive. Three studies with laboratory‐scale silos were made using samples of easy and moderately difficult to ensile forage. In each case, replicate silos containing untreated forage were compared with identical silos containing the same forage to which Lactobacillus parafarraginis DSM 32962 was added to reach an intended concentration of 1 × 108 CFU /kg fresh matter. The results showed that the addition of the additive improves significantly the aerobic stability of the silage tested.
