經過評估，專家小組認為該添加劑對目標物種、消費者和環境都是安全的。該添加劑不是皮膚/眼睛刺激物或皮膚敏化劑，但應被視為呼吸敏化劑。根據所提供的數據，專家小組不能就貝萊斯芽孢桿菌DSM 15544對奶牛或其他反芻動物的功效做出結論。部分原文報道如下：

 

　　Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the assessment of Calsporin? (Bacillus velezensis DSM 15544) as a zootechnical additive for dairy cows and other dairy ruminants. The product under assessment is ba sed on viable spores of Bacillus velezensis DSM 15544. B. velezensis is co nsidered suitable for the qualified presumption of safety (QPS) approach to safety assessment. The identity of the active agent was established and compliance with the applicable qualifications /con firm/ied. Therefore, B. velezensis DSM 15544 is presumed safe for the target species, co nsumers of products derived from animals fed the additive and the environment. Since no co ncerns are expected from the other compo nents of the additive, Calsporin? is also co nsidered safe for the target species, co nsumers of products derived from animals fed the additive and the environment. The additive is not a dermal/eye irritant or a skin sensitiser but should be co nsidered a respiratory sensitiser. The FEEDAP Panel is not in the position to co nclude on the efficacy of Calsporin? for dairy cows or other dairy ruminants ba sed on the data provided.
