2025年3月19日，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DL‐蛋氨酸铬螯合物（chromium chelate of DL-methionine）作为鲑鱼饲料添加剂的安全性和有效性发布科学意见。
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, EFSA was asked to deliver a scientific opinion on the safety and efficacy of a feed additive consisting of chromium chelate of DL-methionine (Availa® Cr) for salmonids. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that the additive is safe for salmonids at the maximum recommended of 600 mg additive/kg complete feed (corresponding to 0.6 mg Cr/kg complete feed). The use of the additive in animal feed is considered safe for the consumers and the environment. The additive is not an eye nor skin irritant. Due to the presence of nickel, the additive is considered a skin and respiratory sensitiser. Inhalation and dermal exposure are considered a risk. The FEEDAP Panel concludes that the additive may have the potential to be efficacious in improving the performance of salmonids at 200 mg additive/kg complete feed (0.2 mg Cr/kg complete feed).
