2025年5月28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）研究小组就贝莱斯芽孢杆菌ATCC PTA-6737 (PB6)作为产蛋母鸡和小型家禽品种饲料添加剂的安全性和有效性以及授权将其使用范围扩大到其他产蛋/繁殖禽类发表科学意见。
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 safety and efficacy of a feed additive consisting of Bacillus velezensis ATCC PTA-6737 (PB6) as a zootechnical feed additive. With the current application, the applicant is seeking the renewal of the authorisation for laying hens and minor poultry species for laying. In addition, the applicant is seeking the modification of the terms of the existing authorisation to obtain the authorisation of a more concentrated form of the additive (from 1 × 1010 to 8 × 1010 colony forming units (CFU)) and the authorisation of the additive for other birds kept for egg production or breeding. The evidence provided showed that the additive complies with the new specifications and the current terms of the authorisation. The FEEDAP Panel concludes that the additive is safe for laying hens, birds kept for egg production or breeding, the consumer and the environment. Regarding safety for the user, the additive is not irritant to the skin and eyes but should be considered a skin and respiratory sensitiser and inhalation and dermal exposure is considered a risk. The additive has the potential to be efficacious in other birds kept for egg production or breeding at the minimum inclusion level of 1 × 108 CFU/kg complete feed.
