2026年5月22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）研究小组就一种内切-1,4-β-木聚糖酶（endo-1,4-β-xylanase）作为所有猪种饲料添加剂的安全性和有效性发表科学意见。
据了解，这种内切-1,4-β-木聚糖酶是由法夫驹形氏酵母ATCC PTA-127053生产的。经过评估，专家小组认为在建议的使用条件下该添加剂对目标物种、消费者和环境是安全的。由于缺乏足够的数据，专家组无法就该添加剂对所有猪种的有效性得出结论。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 the additive containing endo-1,4-β-xylanase produced with Komagataella phaffii ATCC PTA-127053 as a zootechnical feed additive (functional group: digestibility enhancers) for all porcine species. The additive is intended to be used in feed for all porcine species at a recommended minimum level of 90,000 U/kg complete feed for porcine species for fattening and reared for reproduction, and 45,000 U/kg complete feed for reproductive porcine species. In a previous FEEDAP opinion, the production strain was considered suitable for the qualified presumption of safety (QPS) approach to safety assessment and the additive was considered safe for the consumers and for the environment; the Panel also concluded that the additive is not irritant to eyes and skin, but it is considered a dermal and respiratory sensitiser. The FEEDAP Panel could not conclude on the safety for gestating sows and on the efficacy for all porcine species. based on the no observed adverse effect level (NOAEL) derived from a sub-chronic oral toxicity study conducted in rats, the Panel concluded that the additive is safe at the proposed minimum levels for all porcine species. Due to the lack of sufficient data, the Panel was not in a position to conclude on the efficacy for all porcine species.
