2023年12月1日，欧盟食品安全局（EFSA）发布消息，欧盟食品安全局（EFSA）发布关于乳酸肠球菌（Enterococcus lactis）NCIMB 11181作为饲养用于断奶仔猪、育肥犊牛和饲养犊牛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目标物种、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 the authorisation of Enterococcus lactis NCIMB 11181 (Lactiferm®) as a zootechnical additive for weaned piglets, calves for fattening and calves for rearing. The product under assessment is based on a strain originally identified as Enterococcus faecium. During the current assessment, the active agent has been reclassified as Enterococcus lactis. The additive currently authorised is marketed in two formulations: Lactiferm Basic 50 (a solid formulation to be used in feed), and Lactiferm WS200 (a solid ‘water-soluble’ formulation to be used in water for drinking). The applicant has provided evidence that the additive currently on the market complies with the existing conditions of authorisation. The Panel concludes that the use of Lactiferm® under the authorised conditions of use remains safe for the target species (calves up to 6 months and weaned piglets up to 35 kg), consumers and the environment. The Lactiferm WS200 formulation of the additive is not irritant to skin or eyes. Owing to the proteinaceous nature of the active agent, both formulations of the additive are considered respiratory sensitisers. It is not possible to conclude on the irritating potential for skin and eyes of the Lactiferm Basic 50 formulation or on the potential of both forms of the additive to cause skin sensitisation. There is no need for assessing the efficacy of the additive in the context of the renewal of the authorisation.
