2019年2月25日，欧盟食品安全局（EFSA）发布消息，应欧盟委员会要求，欧盟食品安全局就TYFER™（酪氨酸铁螯合物）（TYFER™ （ferric tyrosine chelate））作为家禽、火鸡和小型家禽的动物技术饲料添加剂的安全性和功效发表科学意见。
经过评估，欧盟食品安全局认为，该添加剂在最高预期水平200毫克TYFER /千克全价饲料下对目标物种是安全的。
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 the product TYFER? （ferric tyrosine chelate） as zootechnical feed additive for chickens, turkeys and minor poultry species for fattening or reared for laying/breeding. The additive is safe for chickens for fattening at the maximum expected level of 200 mg TYFER?/kg complete feed; this conclusion can be extended to chickens reared for laying/breeding and extrapolated to turkeys and all minor poultry species for fattening or reared for laying/breeding. No concerns for consumer safety are expected from the use of the additive in poultry nutrition. The EFSA Panel on Additives and Products or Substances used in Animal Feed （FEEDAP） considers that the additive poses a risk to users by inhalation, and should also be considered as an irritant to skin, eyes and mucous membranes. Due to the presence of nickel, ferric tyrosine chelate should also be considered as a dermal and respiratory sensitiser. The supplementation of feed with the additive is not expected to pose an environmental risk.
