2023年3月7日，据欧盟食品安全局（EFSA）消息，应欧盟委员会要求，欧盟动物饲料添加剂和产品（FEEDAP）研究小组就枯草芽孢杆菌（Bacillus subtilis）菌株CNCM I-4606、CNCM I-5043、CNCM I-4607和乳酸乳球菌（Lactococcus lactis）CNCM I-4609作为所有动物饲料添加剂的有效性发表科学意见。
部分原文报道如下：
Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the efficacy of the preparation consisting of viable cells of Bacillus subtilis CNCM I-4606, B. subtilis CNCM I-5043, B. subtilis CNCM I-4607 and Lactococcus lactis CNCM I-4609 when used as a technological additive (hygiene condition enhancer) for all animal species. In a previous opinion, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that the additive is safe for the target species, consumers and the environment. The Panel also considered the additive to be non-irritant to skin and eyes, nor a dermal sensitiser, but a respiratory sensitiser. Moreover, the data provided were not sufficient to conclude on the efficacy of the additive to significantly reduce the growth of Salmonella Typhimurium or Escherichia coli in feed. In the current assessment, the applicant provided supplementary information to address these flaws and limited the claimed effect to ‘prevent (re)contamination by Salmonella Typhimurium’. based on the new studies, the Panel concluded that the additive at a minimum proposed inclusion level of 1 × 109 colony forming units (CFU) B. subtilis and 1 × 109 CFU L. lactis per litre showed potential to reduce Salmonella Typhimurium growth in feeds with high moisture content (60–90% moisture).
