    食品伙伴網訊  2020年1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PHYTAFEED® 20000 GR/L(6-植酸酶(6-phytase))作為豬育肥飼料添加劑的安全性和有效性發表科學意見。
     
      據了解,該添加劑是一種6-植酸酶制劑,其中6-植酸酶由一種轉基因巴斯德畢赤酵母(Komagataella phaffii) 菌株產生。經過評估,FEEDAP小組得出結論認為,此種添加劑不會給消費者和環境帶來安全問題,在1000 U/kg飼料的使用水平下對目標物種是安全的,但無法得出其有效性。
     
      部分原文報道如下:
     
      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 for pigs for fattening. 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 three applications for its use in different species. The Panel concluded in those opinions 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 it should be considered as a respiratory sensitiser. The Panel considered that the new use in pigs for fattening would not modify the previously drawn conclusions with respect to the consumers, users and the environment. A tolerance trial in weaned piglets and a subchronic oral toxicity study were made available to support the safety for the new target species.
