2021年7月20日，据欧盟食品安全局（EFSA）消息，应欧盟委员会要求，动物饲料添加剂和产品（FEEDAP）研究小组被要求就丁基羟基茴香醚（butylated hydroxyanisole）作为猫饲料添加剂的安全性发表科学意见。
部分原文报道如下：
Following a request from the European Commission, the 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 butylated hydroxy anisole (BHA) when used as a technological additive (antioxidant) in feed for cats. BHA is a waxy solid consisting for > 98.5% of the active substance, a mixture of 3-tert-butyl-4-hydroxyanisole and 2-tert-butyl-4-hydroxyanisole and is currently authorised for use in all animal species except in cats. In support of the safety of the additive for the target species, the applicant has submitted a tolerance study which demonstrated that BHA is tolerated by cats at a concentration up to 150 mg/kg complete feed. The additive should be considered a skin, eye irritant and a potential skin sensitiser. Exposure of the user via inhalation was considered unlikely; therefore, a risk is not expected. BHA is authorised as an antioxidant for food use at comparable use levels; therefore, no studies were required to demonstrate the efficacy of BHA as an antioxidant in complete feed for cats.
