2023年11月3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Weizmannia faecalis DSM 32016作为育肥家禽和饲养用于产蛋/繁殖家禽以及哺乳和断奶仔猪饲料添加剂的安全性和有效性发表科学意见。
经过评估，专家小组认为该添加剂在建议的使用水平下对目标物种、消费者和环境是安全的。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 safety and efficacy of Weizmannia faecalis (formerly identified as Bacillus coagulans) DSM 32016 (TechnoSpore50®) as a zootechnical feed additive for poultry reared for breeding/laying/fattening, ornamental birds and suckling and weaned Suidae piglets. The additive is authorised for use in feed for poultry for fattening, ornamental birds and suckling and weaned Suidae piglets. This application sought the extension of use in feed for poultry reared for breeding/laying and the new authorisation in water for drinking for suckling and weaned Suidae piglets, poultry for fattening, reared for breeding/laying and ornamental birds. Moreover, the applicant requested the authorisation of simultaneous use in feed for poultry reared for breeding and laying with coccidiostats. The identity and the lack of toxigenic activity of the active agent was /confirm/ied, and it did not show resistance to relevant antibiotics; therefore, the strain was presumed safe for the target species, consumers and the environment. Since other components did not introduce concerns, TechnoSpore50® was also considered safe for the target species, consumers and the environment. The additive is not a skin/eye irritant but is a respiratory sensitiser. No conclusions could be drawn on the skin sensitisation potential of the additive. TechnoSpore50® was considered to be efficacious in feed for poultry reared for laying/breeding at 1 × 109 CFU/kg and in water for drinking for poultry reared for fattening, poultry reared for laying/breeding, ornamental birds and for suckling and weaned Suidae piglets at 5 × 108 CFU/L. TechnoSpore50® is compatible with halofuginone, diclazuril, monensin sodium, robenidine hydrochloride, salinomycin sodium and monensin sodium + nicarbazin, but not with narasin or narasin + nicarbazin. No conclusions could be drawn on the compatibility of TechnoSpore50® with decoquinate, lasalocid A sodium, semduramicin sodium, nicarbazin or amprolium hydrochloride.
