食品伙伴網(wǎng)訊   2020年5月29日，據(jù)歐盟食品安全局（EFSA）消息，應(yīng)歐盟委員會要求，歐盟動物飼料添加劑和產(chǎn)品（FEEDAP）研究小組就PHYTAFEED（6-植酸酶（6-phytase））作為蛋雞和其他產(chǎn)蛋家禽飼料添加劑的安全性和有效性發(fā)表科學意見。

 

　　據(jù)了解，該添加劑是一種6-植酸酶制劑，由一種轉(zhuǎn)基因巴斯德畢赤酵母（Komagataella phaffii）產(chǎn)生。經(jīng)過評估，專家小組認為該添加劑對目標物種、消費者和環(huán)境是安全的，在使用水平為300 U/kg飼料時，可能對目標物種有效。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 zootechnical feed additive for laying hens and other poultry species for laying. 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/categories. 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 laying hens and other poultry species for laying would not modify the previously drawn conclusions with respect to the consumers, users and the environment. A tolerance trial in laying hens and a subchronic oral toxicity study were made available to support the safety of the additive for the target species/categories subject of this new application; from the results obtained, the Panel concluded that the additive is safe for laying hens at the recommended level of use （300 U/kg feed） with a wide margin of safety and therefore the conclusion was extrapolated to other laying birds.
