2022年7月19日，據歐盟食品安全局（EFSA）消息，應歐盟委員會要求，歐盟動物飼料添加劑和產品（FEEDAP）研究小組就釀酒酵母（Saccharomyces cerevisae ）CNCM I-1077作為奶牛、育肥牛、小型反芻動物和駱駝科動物飼料添加劑的有效性發表科學意見。
經過評估，專家小組認為該添加劑有可能提高用于育肥牛、小型反芻動物和用于肉類生產的駱駝科動物的性能，但無法就該添加劑在擬定使用條件下對奶牛或其他反芻動物的功效做出結論。部分原文報道如下：
Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the re-evaluation of the authorisation of the feed additive containing Saccharomyces cerevisae CNCM I-1077 (Levucell® SC) as a zootechnical additive for ruminants. The additive is already authorised for use in dairy sheep and dairy goats, lambs and horses, calves, all minor ruminant species (for rearing) other than lambs and camelids (for rearing) and dairy cows. The additive is intended for use in complete feed for dairy cows, minor ruminant species for milk production and all camelids at the minimum dose of 4 × 108 CFU/kg and for cattle for fattening and minor ruminant species for fattening at the minimum dose of 5 × 108 CFU/kg. In a previous opinion, the FEEDAP Panel concluded that the additive has a potential to improve the performance of cattle raised for fattening, minor ruminant species and camelids raised for meat production but could not conclude on the efficacy of Levucell® SC for dairy cows or extrapolate to minor dairy ruminant species or dairy camelids. The applicant has provided supplementary information to support efficacy of the additive in dairy cows. based on the data provided, the FEEDAP Panel is not in the position to conclude on the efficacy of the additive for dairy cows or other dairy ruminants under the proposed conditions of use.
