    2023年8月10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）研究小组就地衣芽孢杆菌DSM 33099生产的蛋白酶（protease）作为育肥家禽和饲养用于产蛋/繁殖家禽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。该添加剂在30，000 NFP/千克全价饲料的水平下对所有育肥家禽和饲养用于产蛋/繁殖的家禽物种都是有效的。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 a protease (ProAct 360) produced by a genetically modified strain of Bacillus licheniformis (DSM 33099) as a zootechnical feed additive for poultry species for fattening or reared for laying/breeding. The production strain and its recombinant DNA were not detected in an intermediate concentrated product representative of the final formulation. The final product did not trigger a safety concern with regard to the genetic modification. The Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that ProAct 360 is considered safe for all growing poultry species at the recommended inclusion level of 30,000 NFP/kg complete feed. The use ProAct 360 as a feed additive did not give rise to concerns for the consumers or the environment. The additive is not an eye or a dermal irritant but should be considered a respiratory sensitiser. In the absence of data, no conclusions could be reached on the skin sensitisation potential of the additive. The FEEDAP Panel concluded that the additive has the potential to be efficacious at 30,000 NFP/kg complete feed for all poultry species for fattening or reared for laying/breeding.
