欧盟评估硒酸钠作为饲料添加剂的安全性和有效性
据欧盟食品安全局（EFSA）消息，应欧盟委员会要求，欧盟动物饲料添加剂和产品（FEEDAP）研究小组对硒酸钠（sodium selenate）作为反刍动物营养饲料添加剂的安全性和有效性进行了评估。
经过评估，FEEDAP小组认为该添加剂是一种皮肤过敏剂和呼吸过敏剂，在其作为反刍动物饲料添加剂的预期用途中，是其他授权硒添加剂的替代品，不会进一步增加硒的环境负担，通过注射给反刍动物的硒酸钠能够满足动物需求的有效硒源。
部分原文报道如下：
Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of sodium selenate as a nutritional feed additive for ruminants, when used via an intraruminal bolus in ruminants. The EFSA Panel on Additives and Products or Substances used in Animal Feed （FEEDAP） Panel concludes that based on （i） the estimation of the release of selenium from the bolus, （ii） the similarities in bioavailability with sodium selenite, （iii） the experience with the use of boluses in ruminant nutrition and （iv） the wide margin of safety compared with the maximum tolerable levels of selenium in ruminants, the additive is safe for ruminants. The use of sodium selenate by bolus administration providing a selenium intake not exceeding that resulting from the maximum authorised EU level of total selenium in feed presents no concerns for consumer safety. The additive does not pose a risk to users by inhalation and is considered as non‐corrosive but irritant for the skin and the eyes.
