2025年4月16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）研究小組就硅藻土（Kieselguhr）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，專家小組認為在建議的使用條件下該添加劑對目標物種、消費者和環境是安全的.專家小組得出結論，該添加劑在最低濃度為15，000毫克/千克時是有效的抗結塊劑。部分原文報道如下：
Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of Kieselguhr (diatomaceous earth, three forms: natural, purified calcined and purified flux-calcined) as a technological additive (functional group: anticaking and binder) for all animal species. Kieselguhr is predominantly amorphous silica (non-crystalline silicon dioxide (SiO2)). based on the information submitted, Kieselguhr natural, purified calcined and purified flux-calcined are safe when used at 5000 mg/kg of complete feed in all terrestrial animals. No conclusions can be reached on the safety of its use in aquatic animals. The use of Kieselguhr natural, purified calcined and purified flux-calcined in animal nutrition under the proposed conditions of use is safe for the consumer and the environment. Kieselguhr natural and purified flux-calcined are not irritant to the skin. All the three forms of the additive are irritant to the eyes and should be considered dermal and respiratory sensitisers. Any exposure is considered a risk. The FEEDAP Panel concluded that the additive is effective as a pellet binder. Kieselguhr is efficacious as an anticaking agent at a minimum concentration of 15,000 mg/kg.
