2025年4月10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）研究小组就辣椒素（capsaicin）作为所有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、消费者和环境是安全的，该添加剂有可能成为所有动物饲料中的有效调味添加剂。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 capsaicin as a sensory feed additive for all animal species (flavouring compounds). The additive is specified to have a purity of at least 98% with a ratio of (E)-capsaicin (trans-capsaicin) to (Z)-capsaicin (cis-capsaicin) of ≥ 6:1. The FEEDAP Panel concludes that the additive capsaicin is safe at the recommended maximum use level proposed by the applicant (6.5 mg/kg complete feed) for use in all poultry species, all porcine species, all bovines, ovines, caprines, cervids and camelids, all equids, leporids, salmonids and minor fin fish species, dogs, ornamental birds and ornamental fish. For cats and other species not considered above, 5.3 mg/kg complete feed is considered safe. The use of capsaicin as a feed additive is considered safe for consumers and the environment. Capsaicin is a skin and respiratory irritant and is assumed to be an eye irritant. It is not a dermal sensitiser. Any exposure of users is considered a risk. The Panel concluded that the additive has the potential to be efficacious as a flavouring additive in feed for all animal species under the proposed conditions of use.
