2019年7月25日，欧盟食品安全局（EFSA）发布消息，应欧盟委员会要求，动物饲料添加剂和产品（FEEDAP）研究小组就赖氨酸和谷氨酸锌螯合物（zinc chelates of lysine and glutamic acid （Zinc‐LG））作为所有动物物种营养饲料添加剂的安全性和有效性发表科学意见。
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 zinc chelates of lysine and glutamic acid （Zinc‐LG） as a nutritional feed additive for all animal species. The EFSA Panel on Additives and Products or Substances used in Animal Feed （FEEDAP） Panel concludes that, owing to safety considerations, the simultaneous use of both feed and water supplemented with Zinc‐LG should be avoided. Zinc‐LG is safe for chickens for fattening; this conclusion can be extrapolated to all animal species/categories provided that the maximum authorised levels in the EU for total zinc in feed are not exceeded. No increases in the zinc content of animal tissues and products are expected from the use of Zinc‐LG in animal nutrition. There is no indication that the toxicity of Zinc‐LG is essentially different from that described for inorganic divalent zinc. The use of Zinc‐LG in animal nutrition is of no concern for consumer safety provided that the maximum authorised total zinc levels in feed are respected. Owing to its zinc content, the handling of the additive poses a risk to users by inhalation.
