食品伙伴網(wǎng)訊 2023年10月19日,據(jù)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(chǎn)品(FEEDAP)研究小組就一種內(nèi)切-1,4-β-木聚糖酶(endo-β-1,4-xylanase)作為所有禽類和所有豬科動物飼料添加劑的安全性和有效性。
據(jù)了解,該添加劑是由米曲霉DSM 33700生產(chǎn)的。經(jīng)過評估,專家小組認為在建議的使用條件下該添加劑對目標物種、消費者和環(huán)境是安全的。評估小組認為,在100和200 FXU/千克全價飼料的劑量下,該添加劑可能對所有家禽和所有豬有效。部分原文報道如下:
The additive RONOZYME® WX (CT/L) contains endo-1,4-beta-xylanase produced with a genetically modified strain of the filamentous fungus Aspergillus oryzae; the additive is currently authorised for poultry for fattening, weaned piglets, pigs for fattening, lactating sows and laying hens. The applicant has requested to change the production strain, substituting strain A. oryzae DSM 26372 with A. oryzae DSM 33700, and to extend the use of the additive to all poultry species and all Suidae. RONOZYME® WX (CT/L), manufactured with the production strain A. oryzae DSM 33700, did not give rise to safety concerns with regard to the genetic modification of the production strain. No viable cells of the production strain nor its DNA were detected in an intermediate product representative of both final formulations of the additive. RONOZYME® WX (CT/L) was considered safe for all poultry species and all Suidae at the recommended inclusion levels. The use of RONOZYME® WX CT and L manufactured with the production strain A. oryzae DSM 33700 raised no concerns for consumers. RONOZYME® WX L is not an eye irritant; however, no conclusions could be drawn on the potential of RONOZYME? WX CT to be an eye irritant. Both formulations are not irritant to the skin, but due to the lack of data, the FEEDAP Panel was not able to conclude on the potential of both formulations of the additive to be skin sensitisers. Due to the proteinaceous nature of the active substance, the additive is considered a respiratory sensitiser. The additive manufactured by A. oryzae DSM 33700 raises no safety concerns for the environment. The additive has the potential to be efficacious in all poultry species and all Suidae at 100 and 200 FXU/kg complete feed, respectively.
