2025年4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）研究小组就胍基乙酸（guanidinoacetic acid）作为育肥火鸡和饲养用于繁殖的火鸡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目标物种、消费者和环境是安全的。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 safety and efficacy of guanidinoacetic acid (GAA) when used as zootechnical additive in feed and water for drinking for turkeys for fattening and turkeys reared for breeding, and a preparation of GAA when used in feed for the same target species. The FEEDAP Panel concluded that GAA at 1200 mg/kg complete feed or 600 mg/L water is safe for turkeys for fattening and turkeys reared for breeding. There is no concern on consumer safety resulting from the use of GAA for turkeys at the proposed conditions of use. GAA is not toxic by inhalation, not irritant to skin and eyes and not a dermal sensitiser. The FEEDAP Panel concluded that the use of GAA as feed additive is not expected to pose a risk to the environment. The use of the additive under assessment in animal nutrition at the proposed conditions of use has the potential to be efficacious in turkeys for fattening and turkeys reared for breeding. The above conclusions apply to both the active substance GAA and the preparation of GAA.
