2021年4月21日，欧盟據歐盟食品安全局（EFSA）消息，评估應歐盟委員會要求，牛蒡動物飼料添加劑和產品（FEEDAP）研究小組被要求就牛蒡根提取物（a dried extract from the roots of Arctium lappa L. ）作為貓和狗飼料添加劑的安全性發表科學意見。

在沒有數據的取物全性情況下，專家小組無法對用戶的猫和安全性得出結論。在沒有證據表明提取物在動物飼料中起著調味作用或對適口性有影響的料添情況下，專家小組無法就添加劑的加剂功效得出結論。部分原文報道如下：

Following a request from the European Commission,效性 the EFSA 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 a dried extract prepared from the roots of Arctium lappa L. (A. lappa dry extract) when used as a sensory additive (flavouring compound) in feed for cats and dogs. A. lappa dry extract is specified to contain at least 2% inulin. Since uncertainty remains concerning the nature of up to 77% of the additive, the FEEDAP Panel was unable to conclude on the safety of the extract at the proposed use levels of up to 40 mg/kg complete feed for cats and dogs. In the absence of data, no conclusions can be drawn on the safety for the user. In the absence of convincing evidence that the extract acts as a flavour in animal feed or has an effect on palatability, the FEEDAP Panel was unable to conclude on the efficacy of the additive.
