    歐盟評(píng)估一種L-蘇氨酸作為飼料添加劑的安全性
    日期:2019-11-08  來源:食品伙伴網(wǎng)
      食品伙伴網(wǎng)訊  2019年11月6日,據(jù)歐盟食品安全局EFSA)消息,應(yīng)歐盟委員會(huì)要求,歐盟動(dòng)物飼料添加劑和產(chǎn)品(FEEDAP)研究小組被要求就大腸桿菌(Escherichia coli)菌株CGMCC 11473發(fā)酵產(chǎn)生的L-蘇氨酸(L‐threonine)作為所有動(dòng)物物種營(yíng)養(yǎng)添加劑的安全性發(fā)布科學(xué)意見。
     
      經(jīng)過評(píng)估, FEEDAP研究小組認(rèn)為,該種添加劑對(duì)所有動(dòng)物物種、消費(fèi)者和環(huán)境都是安全的。對(duì)于該添加劑對(duì)皮膚和眼睛是否存在刺激性或是否會(huì)導(dǎo)致皮膚過敏,專家小組無法得出結(jié)論。
     
      部分原文報(bào)道如下:
     
      The l‐threonine under assessment is produced by fermentation with a genetically modified strain of Escherichia coli and it is intended to be used as a nutritional additive for all animal species. In 2017 the Panel on Additives and products or Substances used in Animal Feed (FEEDAP) of EFSA issued an opinion on the safety and efficacy of the product. In that assessment, the Panel could not conclude on the safety of the additive for the target species, consumers and the environment due to the lack of data regarding the characterisation of the production strain and the resulting product. The applicant provided additional data on the identity of the production strain, the genetic modification, the susceptibility to antibiotics and the absence of cells and recombinant DNA of the production strain in the final product. The recipient strain is safe and the genetic modification does not raise concerns. Moreover, viable cells or DNA of the production strain were not detected in the final product. With this new information the FEEDAP Panel concluded that l‐threonine produced by E. coli CGMCC 11473 is safe for the all animal species, the consumers and the environment. The FEEDAP Panel could not conclude on the potential of the additive to be irritant to skin and eyes or on the skin sensitisation potential. It was concluded that there is a risk of exposure to endotoxins by inhalation for persons handling the additive.
