2025年4月9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（thiamine hydrochloride）和硝酸硫胺（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 vitamin B1 (thiamine hydrochloride and thiamine mononitrate) for the renewal of its authorisation as nutritional feed additive for all animal species. The Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that vitamin B1 remains safe for all animal species, consumers and the environment. Thiamine mononitrate is not irritant to the eyes, while hydrochloride is not irritant to skin, but it is irritant to the eyes. Both salts of thiamine are considered skin and respiratory sensitisers, and any exposure is considered a risk. These conclusions would apply, in principle, to any preparations produced with the thiamine mononitrate. The Panel concluded there is no need for assessing the efficacy of the additive in the context of the renewal of the authorisation.
