2022年10月25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）研究小组就酿酒酵母（Saccharomyces cerevisae）CNCM I-1079作为牛犊、所有其他反刍动物以及饲养和育肥用骆驼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目标物种、消费者和环境是安全的。该添加剂不是皮肤或眼睛刺激物，也不是皮肤致敏物，但应被视为呼吸致敏物。另外，评估小组无法就添加剂对目标物种的功效做出结论。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 Saccharomyces cerevisiae CNCM I-1079 when used as a zootechnical additive (gut flora stabilisers and physiological condition stabilisers) for calves, all other ruminant species and for camelids for rearing and for fattening. The product, manufactured in two forms, as a powder and an encapsulated form, is intended for use in complete feed at a minimum inclusion level of 1 × 109 CFU/kg complete feed. S. cerevisiae is considered by EFSA to be suitable for the qualified presumption of safety approach to safety assessment. Since the identity of the strain has been clearly established and the additive is composed mainly by dried cells of the active agent, the use of the additive in animal nutrition is considered safe for the target species, the consumer and the environment. The additive is not a skin or eye irritant, or a skin sensitiser, but should be considered a respiratory sensitiser. However, exposure by inhalation to the encapsulated form is unlikely. The Panel was not in the position to conclude on the efficacy of the additive for the target species.
