2024年7月26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）研究小组就靛蓝胭脂红作为猫、狗和观赏鱼饲料添加剂的安全性发表科学意见。
经过评估，专家小组认为靛蓝胭脂红(纯度至少为85%的色素)在250毫克/千克全价饲料的水平下对猫和狗是安全的，在1000毫克/千克全价饲料的水平下对观赏鱼是安全的。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 of indigo carmine as a colourant feed additive for cats, dogs and ornamental fish. In its previous opinion, the FEEDAP Panel concluded that indigo carmine is safe for cats and dogs at levels up to 250 mg/kg complete feed and for ornamental fish up to 1000 mg/kg complete feed. These conclusions were limited to indigo carmine with a purity of at least 93% colouring matter. For the current assessment, the applicant submitted additional data on the characterisation and on the toxicological profile to support the safety of the additive with the purity of at least 85% colouring matter. based on the new data submitted, the FEEDAP Panel concludes that indigo carmine (purity of at least 85% colouring matter) is safe for cats and dogs at levels up to 250 mg/kg complete feed and for ornamental fish up to 1000 mg/kg complete feed.
