歐盟評(píng)估枯草芽孢桿菌DSM 33862和布氏乳桿菌DSM 12856作為所有動(dòng)物青貯飼料添加劑的安全性和有效性

   食品伙伴網(wǎng)訊  2024年11月7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)研究小組就枯草芽孢桿菌DSM 33862和布氏乳桿菌DSM 12856作為所有動(dòng)物青貯飼料添加劑的安全性和有效性發(fā)表科學(xué)意見(jiàn)。
  
  經(jīng)過(guò)評(píng)估,專(zhuān)家小組認(rèn)為在建議的使用條件下該添加劑對(duì)動(dòng)物物種、消費(fèi)者和環(huán)境是安全的。部分原文報(bào)道如下:
  
  Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on a formulation of Bacillus subtilis DSM 33862 and Lentilactobacillus buchneri DSM 12856 when used as a technological additive to improve ensiling of fresh plant material. The additive is intended for use with fresh plant material with a dry matter (DM) range of 32%–65% at a proposed minimum concentration of 1 × 108 colony forming units (CFU)/kg fresh plant material to be used for all animal species. The bacterial species B. subtilis and L. buchneri are considered by EFSA to be suitable for the qualified presumption of safety approach to safety assessment. The identity of the strains was established, no acquired antimicrobial resistance genes of concern were detected in any of the two active agents and no evidence of toxigenic potential was found in B. subtilis DSM 33862. Therefore, the FEEDAP Panel concluded that the use of the strains as a silage additive is considered safe for all the animal species, for consumers of products from animals fed with the treated silage and for the environment. Regarding user safety, the additive contains microorganisms and therefore should be considered as a potential skin and respiratory sensitiser. The additive is not irritant to skin or eyes. Inhalation and dermal exposure is considered a risk. These conclusions would apply, in principle, to any preparations containing the active agents. The FEEDAP Panel concluded that the additive containing B. subtilis DSM 33862 and L. buchneri DSM 12856 at a minimum concentration of 1 × 108 CFU/kg fresh material has the potential to extend the aerobic stability of silage prepared from fresh plant materials with a DM range of 32%–65%.
