歐盟食品安全局動(dòng)物飼料專家組審查了以下內(nèi)容：

 

    產(chǎn)肉動(dòng)物與寵物的銅需求；

 

    飼料物料與成品中的銅含量；

 

    銅的生物利用度；

 

    飼料成品中銅的計(jì)算背景；

 

    銅對(duì)腸道微生物以及耐藥性的影響；

 

    經(jīng)過(guò)審查相關(guān)數(shù)據(jù)發(fā)現(xiàn)，有必要降低銅在飼料中的限量。

 

    部分原文報(bào)道如下：

 

    The Panel on Additives and Products or Substances used in Animal Feed （FEEDAP） reviewed （i） the copper requirements of food-producing and pet animals, （ii） the copper concentration in feed materials and complete feed, （iii） the copper bioavailability, and （iv） the calculated background copper concentration of complete feed. Also considered were （i） the influence of dietary copper on gut microbiota profile and on the bacterial antibiotic resistance in target animals and （ii） the environmental occurrence of bacterial heavy metal tolerance （copper resistance） and resistance to certain antibiotics. The data collected supported the possibility of a reduction in some of the currently authorised maximum contents （CAMC） for total copper in feed.
