2019年5月15日，据欧盟食品安全局（EFSA）消息，应欧盟委员会的要求，动物饲料添加剂和产品（FEEDAP）研究小组就Natuphos E（6-植酸酶（6‐phytase））作为部分禽类饲料添加剂的安全性和有效性发表科学意见。
据了解，此种添加剂用于蛋鸡、小型家禽和其他禽类的产蛋。Natuphos E的生产菌株是转基因黑曲霉。该饲料添加剂在200 FTU/Kg饲料使用时，对目标物种、消费者和环境是安全的，也能够有效改善蛋鸡的产蛋性能等。

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 safety and efficacy of Natuphos? E （6‐phytase） as a feed additive for laying hens, minor poultry and other avian species for laying. The additive Natuphos? E consists of 6‐phytase （phytase; Enzyme Commission Number 3.1.3.26） and is intended to be used as a feed additive for laying hens, minor poultry and other avian species for laying as a zootechnical additive, functional group of digestibility enhancers. This additive was previously assessed by the FEEDAP Panel in 2017 for avian and porcine species. The production strain of the phytase present in the product is a genetically modified strain of Aspergillus niger. based on the previous opinion, the FEEDAP Panel concluded that the genetic modification of the production strain does not give rise to safety concerns.
