2022年11月30日，据欧盟食品安全局（EFSA）消息，欧盟营养、新型食品和食物过敏源（NDA）研究小组就小浮萍和鼓凸浮萍（整株）（Lemna minor and Lemna gibba whole plant material）作为新型食品的安全性发表科学意见。
经过评估，专家小组得出结论，该营养成分可能存在安全问题，目前无法确定其安全性。部分原文报道如下：
Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on Lemna minor and Lemna gibba whole plant material as a novel food (NF) pursuant to Regulation (EU) 2015/2283. Lemna minor and Lemna gibba are aquatic plants commonly named water lentils. The NF is produced by cultivation of Lemna minor and Lemna gibba plants, washing with water and heat treatment. The main constituents of the NF are water, protein and fibre. The Panel notes that the concentration of trace elements and contaminants in the NF is highly dependent on the conditions of cultivation of the plant and the fertiliser composition. The NF is intended to be used as a vegetable, similar to other leafy vegetables. The target population is the general population. The Panel considers that, with the exception of concerns related to the manganese intake, taking into account the composition of the NF and the proposed conditions of use, the consumption of the NF is not nutritionally disadvantageous. The Panel considers that the risk that the consumption of the NF may trigger allergic reactions in humans is low. The Panel concludes that the NF, in consideration of its proposed uses and the concentration of manganese as compared to the normally present concentration of manganese in other leafy vegetables, may be of safety concern, therefore, the safety of the NF cannot currently be established.
