2024年3月11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）研究小组就硫酸氢钠（sodium bisulphate）作为除水生动物外所有动物饲料添加剂的安全性和有效性发表科学意见。
经过评估，专家小组认为在建议的使用条件下该添加剂对所有陆生动物物种、消费者和环境是安全的。在授权更新的情况下，没有必要评估添加剂的功效。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 assessment of the application for renewal of authorisation of sodium bisulphate (SBS) as a feed additive for all terrestrial animal species (category: technological additive; functional group: preservative), and for all terrestrial animal species other than cats, mink, pets and other non-food-producing animals (category: technological additive; functional group: acidity regulator). EFSA has also been asked to assess the new use of the product as an acidity regulator and flavouring compound in all pets and other non-food-producing animals except aquatic animals. The applicant provided evidence that the additive currently in 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 terrestrial animal species, consumer and the environment under the authorised conditions of use. The FEEDAP Panel considers that the proposed new use would not introduce risks not already considered in the previous assessment and therefore the same conclusions on all terrestrial animal species, consumers of products from animals fed the additive and the environment would apply. Regarding user safety, the additive is irritant to the skin, eyes and the respiratory tract, and should be considered a skin and respiratory sensitiser. There is no need to assess the efficacy of the additive in the context of the renewal of the authorisation. The Panel considers that the additive has the potential to be efficacious as an acidity regulator and sensory additive (flavouring compound) in feed for pet and non-food-producing animals (except aquatic animals).
