欧盟评估海泡石作为所有动物饲料添加剂的安全性和有效性

经过评估，专家小组认为在建议的使用条件下该添加剂对奶牛等其他乳反刍动物是安全的，由于缺乏足够的数据，无法得出添加剂对其他目标物种/类别的安全性的结论。在建议的使用条件下，海泡石作为所有动物物种饲料中的增稠剂-悬浮剂、粘合剂和抗结块剂是有效的。部分原文报道如下：

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 the re-evaluation of the authorisation of sepiolite as a feed additive for all animal species. The FEEDAP Panel considered that sepiolite is unlikely to be absorbed. Harmful amounts of residues of any chemical component in edible tissues/products, as a consequence of the use of sepiolite as a feed additive, are not expected. Sepiolite is not genotoxic and does not induce any toxicity effects following oral administration and, therefore, it was considered safe for the consumers. The additive was considered safe for dairy cows at the recommended use level with a safety factor of 2.5. The conclusion was extrapolated to other dairy ruminants but owing to the lack of sufficient data, no conclusions can be drawn on the safety of the additive for the other target species/categories. based on the results of a chronic inhalation toxicity study, the additive is considered a respiratory irritant. Owing to the dusting potential of the additive and its silica content, handling the additive was considered a risk by inhalation for the users. It is not irritant or corrosive to skin or eyes. Due to the nickel content, it is considered a skin and respiratory sensitiser. The additive was considered safe for the environment. The FEEDAP Panel concluded that sepiolite was efficacious as a thickener-suspending agent, binder and anticaking agent in feed for all animal species under the proposed conditions of use.
