欧盟食品安全局动物饲料专家组审查了以下内容:
产肉动物与宠物的铜需求;
饲料物料与成品中的铜含量;
铜的生物利用度;
饲料成品中铜的计算背景;
铜对肠道微生物以及耐药性的影响;
经过审查相关数据发现,有必要降低铜在饲料中的限量。
部分原文报道如下:
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.
