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）研究小组就由羟丙基甲基纤维素（hydroxypropyl methyl cellulose）和甲基纤维素（methyl cellulose）组成的饲料添加剂对所有动物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。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 methyl cellulose and methyl cellulose as technological feed additives for all animal species. In its previous opinions on the safety and efficacy of the products, 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 additives hydroxypropyl methyl cellulose and methyl cellulose were properly identified and characterised and were shown to meet the specifications set for the food additives. Therefore, the conclusions of the safety assessments reached in the previous opinions for hydroxypropyl methyl cellulose and methyl cellulose meeting the food additive specifications, apply to the hydroxypropyl methyl cellulose and methyl cellulose under assessment as feed additives. The additives are 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.
