2024年2月29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）研究小组就羟丙基纤维素（hydroxypropyl cellulose）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，专家小组认为该添加剂对目标物种、消费者和环境都是安全的。在缺乏数据的情况下，专家小组无法对用户的安全性做出结论。部分原文报道如下：
Following a request from the European Commission, the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety of hydroxypropyl cellulose as a technological feed additive for all animal species. In its previous opinions on the safety and efficacy of the product, the FEEDAP Panel could not conclude on proper identification and characterisation as required for a feed additive. The occurrence of potential toxic impurities could also not be assessed. based on the new data provided, the feed additive hydroxypropyl cellulose was properly identified and characterised and was shown to meet the specifications set for the food additive. Therefore, the conclusions of the safety assessment reached in the previous opinion for hydroxypropyl cellulose meeting the food additive specifications, apply to the hydroxypropyl cellulose under assessment as a feed additive. The feed additive is considered safe for all animal species, the consumer and the environment. In the absence of data, the FEEDAP Panel is not in the position to conclude on the safety for the user.
