2024年11月7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）研究小组就阿舒假囊酵母（Eremothecium ashbyi）CCTCCM 2019833生产的维生素B2（核黄素）作为所有动物饲料添加剂的安全性发表科学意见。
经过评估，专家小组认为在建议的使用条件下，该添加剂对目标物种和消费者是安全的。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 of a feed additive consisting of vitamin B2/riboflavin produced with Eremothecium ashbyi CCTCCM 2019833 intended for use as a nutritional additive (functional group: vitamins, pro-vitamins and chemically well-defined substances having similar effects) for all animal species. The characterisation, safety and efficacy of the additive have been already assessed previously; however, the FEEDAP Panel could not conclude on the safety of the additive for the target species, consumers and the users due to lack of reliable toxicological data. In the present assessment, the applicant submitted new genotoxicity and repeated dose oral toxicity studies. After the assessment of the data newly submitted, the FEEDAP Panel concluded that the use of the feed additive in animal nutrition under the conditions of use proposed is of no safety concern for the target species and the consumer. The additive is not a skin/eye irritant nor a skin sensitiser, but it is considered a respiratory sensitiser.
