2022年4月21日，欧盟食品安全局（EFSA）发布消息，欧盟食品安全局（EFSA）发布关于乳酸乳球菌（Lactococcus lactis）NCIMB 30117作为所有动物饲料添加剂的授权更新申请的评估。
经过评估，专家小组得出结论，该添加剂在授权使用条件下对所有动物物种、消费者和环境都是安全的。在授权更新的情况下，无需评估添加剂的功效。部分原文报道如下：
Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of the application for renewal of Lactococcus lactis NCIMB 30117 as a technological additive for use in forage for all animal species. The additive aims to improve the production of silage and is authorised for all animal species. The applicant has provided evidence that the additive currently on the market complies with the existing conditions of authorisation. There is no new evidence that would lead the FEEDAP Panel to reconsider its previous conclusions. Thus, the Panel concludes that the additive remains safe for all animal species, consumer and the environment under the authorised conditions of use. Regarding user safety, the additive should be considered as a respiratory sensitiser. No conclusions can be drawn on the skin sensitisation, and eye and skin irritancy potential of the additive. There is no need for assessing the efficacy of the additive in the context of the renewal of the authorisation.
