本报讯 一种快速生长的三文鱼日前成为美国批准的全球第一种获准上市供人类食用的转基因动物。


由美国食品药品监督管理局(FDA)于11月19日作出的这一决定将三文鱼从20年的监管困境中解放出来。然而此举迅速遭到了一些环境及食品安全团体的反对。


但对于这项技术的倡导者而言,这一政策的出台可谓是一个漫长而恼人的等待过后的安慰。他们表示,它可以刺激其他转基因动物的发展。


“它开启了利用这一技术的可能性。”加利福尼亚大学戴维斯分校动物遗传学家Alison Van Eenennaam表示,“监管障碍真的曾阻止全世界使用这项技术。”


这种转基因鱼名为“基因改造”三文鱼,是由马萨诸塞州的梅娜德AquaBounty技术公司培育的,它能够比野生三文鱼更高水平地表达一种生长激素。这种转基因鱼长足尺寸只需18个月而非3年。


按照这项技术的支持者所言,这些基因修饰意味着每公斤收获的鱼只需要更少量的食物和其他资源,并且转基因三文鱼还可以减轻因过度捕捞对野生三文鱼种群造成的压力。


然而反对者却担心转基因鱼会从它们的养殖场中逃脱进而改变自然生态系统。他们同时还批评没有要求这些肉类食品必须贴上转基因标签。


华盛顿哥伦比亚特区环保组织食品安全中心政策分析专家Jaydee Hanson表示:“许多人都说:‘是的,我们希望它们被贴上标签。’”Hanson说,“如果这是一个很好的产品,那么企业自身就应该为它贴上标签。”


FDA在2010年完成了转基因三文鱼的食品安全评估,并在2012年底发布了其环境影响报告。完成这些步骤和最后决定之间的长期延误有传闻是由于政治干预所致。然而FDA下属兽医医学中心政策分析专家Laura Epstein指出,之所以用了这么长时间才批准转基因三文鱼上市完全因为它是第一种供人类食用的转基因动物。她说:“与大多数同类中第一个上市的产品一样,我们都会非常小心。”Epstein同时强调,该机构在最终作决定之前还要费力通过一系列公众评论。


FDA拒绝就其他申请是否在批准的监管通道上发表评论。Van Eenennaam表示,目前还不清楚该机构将如何处理使用最新基因组编辑技术(例如CRISPR)进行转基因操作的动物。


FDA兽医医学中心在一份声明中说,基于可靠的科学证据及全面评估,FDA确定转基因三文鱼的数据与信息满足监管要求,“包括利用这种鱼类制成的食品可以安全食用”。


普通的大西洋三文鱼通常在春夏季节的温暖水流中发育生长,需要3年才能长大。此次获得批准的转基因三文鱼,是通过在大西洋三文鱼的受精卵中植入太平洋奇努克三文鱼的生长激素基因及大洋鳕鱼的抗冻蛋白基因培育的。


太平洋奇努克三文鱼是鲑鱼家族中体形最大的一种,而大洋鳕鱼的抗冻蛋白让其可以在寒冷的水域中生存。这样,转基因大西洋三文鱼能在寒冷的环境中分泌生长激素,让生长周期缩短为一年半,“身材”也要大得多。


FDA详细说明了批准转基因三文鱼上市的原因。首先,满足监管规定,包括该三文鱼可安全食用、基因改造对鱼自身是安全的以及有关加快生长速度的说法属实。


其次,转基因三文鱼与普通三文鱼一样有营养,并没有因为经过转基因处理而与普通三文鱼有营养上的差异。


第三,转基因三文鱼只能养殖在加拿大和巴拿马两个封闭的陆上养殖场内,不得在美国和其他地方养殖。


第四,该公司采取多种措施防止转基因三文鱼逃到野外,包括给养殖槽和出水管加装多重物理防护设施。此外,这些三文鱼都不具有繁殖能力,就算进入自然环境,也不可能与野生三文鱼交配产生种群,因此对环境“将不会产生明显影响”。


FDA说,将对转基因三文鱼的养殖及其设施进行监管,并通过检查确保三文鱼养殖场采取足够物理防护措施。此外,加拿大和巴拿马政府也将对生产设施进行检查。


FDA当天还发布两项有关转基因动物和植物标识的规定,称像转基因三文鱼这样的转基因食品与其非转基因的对应食品在物质上并没有区别,因此不用进行强制标识。(赵熙熙)
