欧盟评估一种6植酸酶作为饲料添加剂的安全性和有效性

　　2019年11月7日，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）研究小组就PHYTAFEED® 20,000 GR/L（6-植酸酶（6-phytase））作为火鸡和小型家禽饲料添加剂的安全性和有效性发表科学意见。

　　据了解，该添加剂是一种6-植酸酶制剂，其中6-植酸酶由一种转基因巴斯德毕赤酵母（Komagataella phaffii） 菌株产生。经过评估，FEEDAP小组得出结论认为，此种添加剂不会给消费者和环境带来安全问题，在250 U/kg饲料的使用水平下对目标物种有效。

　　Following a request from the European Commission, the EFSA 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 APSA PHYTAFEED® 20,000 GR/L （6‐phytase） as a feed additive turkeys for fattening, turkeys reared for breeding and minor poultry species. The additive is a preparation of 6‐phytase produced by a genetically modified strain of Komagataella phaffii and has been previously assessed by the FEEDAP Panel in the context of an application for its use in feed for chickens for fattening. The Panel concluded in that opinion that the production strain is safe, and that the use of the additive as a feed additive would raise no safety concerns for the consumers and the environment. The additive was also considered not to be irritant to skin or eyes or a dermal sensitiser but that should be considered as a respiratory sensitiser. The Panel considered that the new use in turkeys would not modify the previously drawn conclusions with respect to the consumers, users and the environment.
