第一、凡是出口产品,不允许使用的抗生素成分有:氯霉素、庆大霉素、甲砜霉素、金霉素、阿维菌素、土霉素、四环素等多种抗生素,都是因为这些抗生素对人体有间接的致癌危害。

第二、磺胺类:长期应用能造成积蓄中毒,其残留能破坏人造血系统,造成溶血性贫血症、粒细胞缺乏症、血小板减少症等。

第三、喹乙醇:在饲料中添加可促进畜禽生长,因其效果好,价格便宜,饲料厂普遍使用。但它是一种基因毒剂,生殖腺诱变剂,有致突变、致畸和致癌性。

第四、氯霉素:其对畜禽的不良反应是对造血系统有毒性,使血小板、血细胞减少和形成视神经炎,雏鸡肝内酶系统尚未发育完全,影响肝对氯霉素的解毒,肾脏排泄功能低下,使氯霉素滞留。其残留的潜在危害是氯霉素对骨髓造血机能有抑制作用,可引起人的粒细胞缺乏病,再生障碍性贫血和溶血性贫血,对人产生致死效应。

第五、土霉素:长期大剂量使用土霉素能引起肝脏损伤以致肝细胞坏死,致使中毒死亡。如未执行停药期间规定,残留使人体产生耐药性,影响抗生素对人体疾病的治疗,并易产生人体过敏反应。

第六、硫酸庆大霉素:用于养鸡中易出现尿酸盐沉积、肾脏肿大、过敏休克和呼吸抑制,特别是对脑神经前庭神经有害,而且反复使用易产生耐药性。

第七、呋喃唑酮(痢特灵):续长期应用,能引起连出血综合症。如不执行停药期的规定,在鸡肝、猪肝、鸡肉中有残留,其潜在危害是诱发基因变异和致癌。

第八、也有一些要求在出栏前14天停用的抗生素,如青霉素、链霉素;要求出栏前5天停用的抗菌素,有恩诺沙星、泰乐菌素;要求出栏前3天停用的抗生素,有盐霉素、球痢灵。为了人类安全、健康和食品安全,每个养殖从业者,都应科学、谨慎使用抗生素。
