食品伙伴網(wǎng)訊  2019年1月31日，歐盟食品安全局（EFSA）發(fā)布用作飼料添加劑的轉(zhuǎn)基因枯草芽孢桿菌產(chǎn)生的維生素B2對人類造成風(fēng)險(xiǎn)的聲明。

 

　　應(yīng)歐盟委員會要求，歐洲食品安全局就飼料添加劑中存在的轉(zhuǎn)基因物質(zhì)對人類構(gòu)成的風(fēng)險(xiǎn)提供科學(xué)建議，特別是在抗微生物藥物耐藥性（AMR）方面。EFSA評估了歐盟食品和飼料類快速預(yù)警系統(tǒng)（RASFF）關(guān)于添加劑和飼料中AMR基因存在的分析數(shù)據(jù)，結(jié)果顯示檢測出轉(zhuǎn)基因枯草芽孢桿菌DNA的存在呈陽性。

　　The detection of recombinant DNA in a vitamin B2 used as feed additive was notified by the Belgian national authorities on 2 October 2018 via the Rapid alert System for Food and Feed （RASFF）。 The European Commission requested scientific advice from EFSA on the risk posed to humans by the presence of genetically modified material in the feed additive, particularly with regard to antimicrobial resistance （AMR）。 EFSA assessed the analytical data from RASFF regarding the presence of AMR genes in both additive and feed. Samples of the additive and feed tested positive for presence of DNA of a genetically modified Bacillus subtilis. The results were compatible with, but did not demonstrate the presence of, a full-length chloramphenicol resistance gene. No information was made available on the presence of other AMR genes or viable cells of the Bacillus subtilis. The statement provides a risk assessment pathway indicating the events needed to produce adverse human health effects from the presence of AMR genes in feed additives. Data on the likelihood of occurrence of all events are needed to produce an evidence-based estimate of the risk. All the events are theoretically possible, but there are no scientific data available to estimate the probability of each taking place.
