2026年4月15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）研究小组就由常春藤提取物和百里香酚组成的饲料添加剂对除家禽、观赏鸟和水生动物外所有动物物种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 a feed additive consisting of an extract from the dried leaves of Hedera helix L. (common ivy extract) and thymol, when used as a sensory additive in feed for all animal species and categories except poultry, ornamental birds and all aquatic animal species. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that the additive under assessment is safe up to the maximum proposed use levels in complete feed of 450 mg/kg for piglets and veal calves; 300 mg/kg for pigs for fattening, sows, rabbits and guinea pigs; 280 mg/kg for horses; 250 mg/kg for ruminants; and 600 mg/kg for dogs and cats. These levels are extrapolated to physiologically related species. For any other species, the additive is safe at 250 mg/kg complete feed. The use of the additive in animal feed under the proposed conditions of use is safe for the consumer and the environment. Regarding user safety, the extract under assessment should be considered as irritant to skin and eyes and respiratory sensitiser. Exposure of users by any route is considered a risk. The data provided indicate that the additive under assessment (common ivy extract and thymol) has the potential to be efficacious as a sensory additive in feed. However, the Panel notes that, considering the well-known flavouring properties of thymol, it is not possible to conclude on the flavouring properties of the common ivy extract alone.
