2026年10月7日，欧盟食品安全局（EFSA）发布消息，欧盟食品安全局发布关于胍基乙酸及其制剂作为育肥鸡、繁殖/产蛋鸡、断奶仔猪和育肥猪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 feed additives guanidinoacetic acid (GAA) and a preparation of GAA (Creamino®) for chickens for fattening and reared for laying and breeding, weaned piglets and pigs for fattening for the renewal of their authorisation and their extension of use in feed for suckling pigs. The additives are already authorised for use in chickens for fattening and reared for laying and breeding, weaned piglets and pigs for fattening. The FEEDAP Panel concludes that the additives remain safe for the target species, consumers and environment and that the extension of the use to suckling piglets would not affect these conclusions. Regarding user safety, the additives were not considered irritant to skin or eyes and were not considered a potential skin sensitiser. There is no need for assessing the efficacy of the additives in the context of the renewal of the authorisation for chickens for fattening, chickens reared for laying and breeding, weaned piglets and pigs for fattening. The Panel concludes that the additives are efficacious in feed for suckling piglets at 600 mg/kg complete feed.
