2023年9月29日，欧盟食品安全局（EFSA）发布消息，欧盟食品安全局（EFSA）发布关于氢氧化钠（sodium hydroxide）作为狗、猫和观赏鱼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所有动物物种和环境都是安全的。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, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the assessment of the application for renewal of authorisation of sodium hydroxide as a technological additive (acidity regulator) for dogs, cats and ornamental fish. The applicants have provided evidence that the additive currently on the market complies with the existing conditions of authorisation. There is no evidence that would lead the FEEDAP Panel to reconsider its previous conclusions. Thus, the Panel concluded that the additive remains safe for all animal species and the environment under the authorised conditions of use. Regarding user safety, the additive is corrosive and therefore the provision of the authorisation that ‘breathing protection, eye protection, gloves and protective clothing shall be used during handling’ should be /confirm/ied. There is no need for assessing the efficacy of the additive in the context of the renewal of the authorisation.
