2025年4月11日，欧盟食品安全局（EFSA）发布消息，欧盟食品安全局发布关于酿酒酵母CBS 493.94作为奶牛、小型哺乳反刍动物、育肥牛和育肥小型反刍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 authorisation of a preparation of dried cells of Saccharomyces cerevisiae CBS 493.94 (Yea-Sacc®) as a zootechnical additive for dairy cows, minor dairy ruminant species, cattle for fattening and minor ruminant species for fattening. The feed additive is marketed in two solid forms (Yea-Sacc® C and Yea-Sacc® TS) differing by the granulometry. The applicant provided evidence that the additive currently in the market complies with the existing terms of the authorisation. The Panel concluded that the additive remains safe for the target species, consumers and the environment. Regarding the safety for the user, Yea-Sacc® TS is non-irritant to the skin or eyes while Yea-Sacc® C is not irritant to the skin but irritant to the eyes. The additive in both formulations should be considered a skin and respiratory sensitiser and any exposure through skin and respiratory tract is considered a risk. There is no need to assess the efficacy of the additive in the context of the renewal of the authorisation.
