2022年5月5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）研究小组就日落黄FCF作为猫和狗、观赏鱼、食粮观赏鸟和小型啮齿动物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是安全的，但无法对添加剂的功效做出结论。部分原文报道如下：
Following a request from the European Commission, the EFSA 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 Sunset Yellow FCF for cats, dogs, ornamental fish, grain-eating ornamental birds and small rodents when used as an additive that adds or restores colour in feedingstuffs. Sunset Yellow FCF is considered safe for the target species at the following concentrations in complete feed: 165 mg/kg for cats, 198 mg/kg for dogs, 733 mg/kg for ornamental fish, 24 mg/kg for grain-eating ornamental birds and 750 mg/kg for small rodents. In the absence of adequate information, the FEEDAP Panel cannot conclude neither on the eyes and skin irritation potential of Sunset yellow FCF, nor on its skin sensitisation potential. Exposure by inhalation is considered to be unlikely. The FEEDAP Panel cannot conclude on the efficacy of the additive.
