2025年4月28日，欧盟食品安全局（EFSA）发布消息，欧盟食品安全局（EFSA）发布关于盐酸硫胺素（thiamine hydrochloride）和硝酸硫胺素（thiamine mononitrate）作为所有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 safety and efficacy of thiamine hydrochloride and thiamine mononitrate (vitamin B1) for the renewal of its authorisation as nutritional feed additives for all animal species. The Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that thiamine mononitrate and thiamine hydrochloride remain safe for all animal species, consumers and the environment. Regarding the user safety, both thiamine salts are regarded as skin and eye irritants, and skin and respiratory sensitisers. The Panel concluded there is no need for assessing the efficacy of the additives in the context of the renewal of the authorisation.
