2021年7月30日，據歐盟食品安全局（EFSA）消息，應歐盟委員會要求，歐盟動物飼料添加劑和產品（FEEDAP）研究小組就野油菜黃單胞桿菌（Xanthomonas campestris strains）菌株生產的黃原膠（xanthan gum）作為所有動物飼料添加劑的安全性和有效性發表科學意見。
經過評估，在缺乏關于評估中的添加劑的充分信息的情況下，專家小組無法就黃原膠對目標物種、消費者、使用者和環境的安全性得出結論。在建議的使用條件下，黃原膠被認為是所有動物品種飼料中有效的穩定劑和增稠劑。部分原文報道如下：
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 xanthan gum as a feed additive for all animal species. Xanthan gum is manufactured using different production strains belonging to the X. campestris species. The identity of the strains producing xanthan gum was not unambiguously established, data on antimicrobial susceptibility were incomplete, and it was not possible to exclude the presence in the additive of viable cells/DNA of the production strains. Consequently, no conclusions could be drawn on the safety of the X. campestris strains ■■■■■. Considering the above and in the absence of adequate information on the additive under assessment, the FEEDAP Panel cannot conclude on the safety of xanthan gum produced by the X. campestris strains ■■■■■ for the target species, the consumer, the user and the environment. Xanthan gum is considered as an efficacious stabiliser and thickener in feedingstuffs for all animal species at the proposed conditions of use.
