欧盟评估戊糖片球菌DSM 32292作为所有动物饲料添加剂的安全性和有效性

 　　  2022年7月18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）研究小组就戊糖片球菌（Pediococcus pentosaceus） DSM 32292作为所有动物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，该添加剂对所有牲畜品种、消费者和环境都是安全的。建议用量为5×10⁷CFU/kg饲料具有提高中等难度至青贮饲料的青贮饲料产量的潜力。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 (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of Pediococcus pentosaceus DSM 32292 as a technological additive for all animal species. The additive is intended to improve the production of silage at a proposed application rate of 5 × 10⁷ colony forming units (CFU)/kg forage. The bacterial species P. pentosaceus is considered by EFSA to be suitable for the qualified presumption of safety (QPS) approach. As the identity of the strain has been established and no antimicrobial resistance determinants of concern were detected, the use of the strain as a silage additive is considered safe for livestock species, for consumers and for the environment. In the absence of data, the FEEDAP Panel cannot conclude on the potential of the additive to be a skin/eye irritant or a skin sensitiser. Given the proteinaceous nature of the active agent, the additive should be considered a respiratory sensitiser. The additive at the proposed application rate of 5 × 10⁷ CFU/kg forage has the potential to improve the production of silages from moderately difficult to ensile forages.
