2021年4月28日，據歐盟食品安全局（EFSA）消息，應歐盟委員會要求，歐盟動物飼料添加劑和產品（FEEDAP）研究小組就一種內切-1,4-β-木聚糖酶（endo‐1,4‐β‐xylanase ）作為斷奶仔豬、育肥豬、育肥雞、產蛋雞、蛋雞、育肥火雞、養殖火雞和小型家禽品種飼料添加劑的安全性和有效性。
據了解，該添加劑是由里氏木霉CBS 140027生產的。部分原文報道如下：
Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of ECONASE? XT (endo‐1,4‐β‐xylanase) produced by a genetically modified strain of Trichoderma reesei (CBS 140027) as a zootechnical feed additive for piglets (weaned), pigs for fattening, chickens for fattening, chickens reared for laying, laying hens, turkeys for fattening, turkeys reared for breeding and minor poultry species. The recipient strain and the production strain T. reesei CBS 140027 are considered safe. The additive is safe for chickens for fattening and weaned piglets at the maximum recommended doses (16,000 and 24,000 BXU/kg feed, respectively) with a wide margin of safety (100‐fold and 50‐fold, respectively). These conclusions are extended to chickens reared for laying and to pigs for fattening at 16,000 and 24,000 BXU/kg feed, respectively. The additive is safe for turkeys for fattening or reared for breeding at 16,000 BXU/kg feed. The FEEDAP Panel cannot conclude on the safety of the additive for laying hens and for minor poultry species for laying at the proposed conditions of use. The information provided does not allow to conclude on the safety of the use of EConASE XT? P/L produced by T. reesei CBS 140027 in animal nutrition for the consumers. The use of the additive under assessment in animal nutrition does not raise safety concerns for the environment. ECONASE? XT L is non‐irritant to the skin or to the eyes. In absence of data, the FEEDAP Panel cannot conclude on the potential of the solid product to be irritant to skin and eyes and on the potential of the additive in all forms to be a dermal sensitiser. All forms of the additive should be considered as respiratory sensitisers. All forms of the additive are considered efficacious at the minimum recommended levels for the target species.
