2023年4月20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）研究小组就茴香油作为家禽和马饲料添加剂、茴香酊剂作为家禽、狗、猫和马饲料添加剂的安全性和有效性发表科学意见。
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 anise oil and anise tincture obtained from the fruit of Pimpinella anisum L., when used as sensory additives. The use of the anise oil at the proposed use level in complete feed of 1.9 mg/kg for laying hens and 5 mg/kg for horses was considered of low concern. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) had no safety concern when anise oil is used at the proposed use levels of 1.5 mg/kg for chickens for fattening and at 1.7 mg/kg for turkeys for fattening. The use of anise tincture at the proposed conditions of use was considered of low concern in dogs, cats, horses and laying hens, and of no concern in chickens for fattening. The use of the additives up to the highest level in feed which was considered of low or no concern for target animals was also expected to be of no concern for consumers. The additives under assessment should be considered as irritants to skin and eyes, and as dermal and respiratory sensitisers. Due to the high concentration of estragole (≥ 1%), anise oil is classified as suspected of causing genetic defects and of causing cancer and should be handled accordingly. When handling anise tincture, exposure of unprotected users to estragole may occur. Therefore, to reduce the risk, the exposure of the users should be minimised. The use of these additives in animal feed was not expected to pose a risk to the environment. Since the fruit of P. anisum and its preparations are recognised to flavour food and their function in feed would be the same, no further demonstration of efficacy was considered necessary.
