2019年3月4日，欧盟食品安全局（EFSA）发布消息，应欧盟委员会要求，欧盟动物饲料添加剂和产品（FEEDAP）研究小组被要求就Beltherm MP/ML作为猪饲料添加剂的安全性和有效性发表科学意见。

 

　　据了解Beltherm MP/ML含有内切- 1，4 -β-木聚糖酶，可作为断奶仔猪、育肥猪和育肥小种猪的动物技术添加剂。经过评估，专家小组得出结论此添加剂对目标物种是安全的，在推荐水平下有可能有效。

　　Beltherm MP/ML contains endo-1,4-beta-xylanase and it is to be used as a zootechnical additive for weaned piglets, pigs for fattening and minor porcine species for fattening. The safety and efficacy of the additive when used for poultry species have been evaluated previously by the EFSA Panel on Additives and Products or Substances used in Animal Feed （FEEDAP Panel）。 In that assessment, the safety for the consumers, environment and the users was assessed. The applicant has requested for the authorisation in new species/categories. The Panel considered that the new use would not introduce hazards that have not already been considered. Therefore, it was concluded that the additive is safe for the consumers and the environment. Considering the safety for the user, the Panel concluded that the additive, in either form, is not toxic by inhalation or irritant for skin or eye but it is considered a potential respiratory sensitiser. The Panel could not conclude on the dermal sensitisation potential of the additive. In a trial with weaned piglets, the animals tolerated well a 200-fold the level recommended in feed by the applicant; therefore, the Panel concluded that the additive is safe for weaned piglets, pigs for fattening and minor porcine species at the recommended level. based on the data provided to support the efficacy of the additive in weaned piglets and pigs for fattening, the Panel concluded that the additive has the potential to be efficacious at the recommended level in those species/categories. The conclusions on the safety and efficacy for weaned piglets and pigs for fattening were extrapolated to minor porcine species.
