近年来,转基因农作物及其副产品以其独有的优势在世界粮食和饲料资源中扮演了越来越重要的角色。但到目前为止,人们对于转基因作物的安全性仍然没有一个定论。围绕转基因农作物及其副产品用作食品及饲料的安全性问题,各国学者作了大量研究。本文综述了近年来转基因农作物及其副产品的安全性问题由来及其用作动物饲料时与非转基因作物相比的安全性和饲喂价值差异等方面的一些研究进展,并对未来转基因农作物饲用安全性的研究方向提出了作者的观点。 相似文献

随着全球农业生物技术产业的迅速发展,转基因作物种植面积日益迅速扩大。这些转基因作物与人类的食物和动物的饲料密切相关。近年来,转基因作物及其产品作为饲料原料的安全性问题越来越引起人们的关注。转基因饲料安全与转基因食品安全二者紧密相关,前者也是后者的重要环节,因此本文将转基因饲料安全问题与转基因食品安全问题一同加以阐述。 相似文献

转基因技术带来了很多高产优质和具有特殊用途的作物品种,随着转基因技术的迅速发展与应用,现已有大量的转基因作物用为饲料原料,由此引发了人们对转基因作物、对食物链安全乃至对环境、生态系统安全的忧虑。那么,转基因作物及其加工副产品进入饲料,对饲养动物的安全性影响如何,进而可能对人类健康造成何种影响。从央视主持人崔永元赴美考察的纪录片、新浪网以及农业部网站的科普问答,到"两会"的讨论,再到专家学者的试验研究,人们都在试图找到关于转基因的清晰认知与明了答案…… 相似文献

目前大部分转基因（GM）植物及其产品被用作饲料原料,而且随着今后转基因技术的不断发展,转基因植物种类将会不断增多。但转基因饲料的安全性一直受到质疑,我国对转基因问题一贯持谨慎态度,于2002年颁布了《农业转基因生物标识管理办法》,规定作为饲料原料的转基因豆粕、玉米、油菜籽粕,必须进行标识。鉴于转基因饲料存在非预期风险,对转基因饲料的使用应加强监管,确保动物源性食品安全。 相似文献

转基因生物的安全性 总被引：7，自引：0，他引：7
随着转基因技术日趋成熟,由实验室走向大田中试,不少转基因作物及其产品已在生活中与人们休戚相关。与此同时,转基因作物的生态风险,可能带来的环境问题、转基因产品作为食品对人体的健康问题和产品流通过程中的加贴标签问题、运输问题、国际贸易问题、知识产权问题等,已引起世界性的“生物安全”的讨论。我国进口的转基因作物排在前3位的是大豆、玉米、油菜籽。这些转基因食品,一方面经加工后直接进入人们的餐桌;另一方面大豆、油菜籽加工后的副产品(如豆粕、菜粕)以及玉米等作为饲料饲喂畜禽后间接进入人们的生活。关注转基因生物的同时,也正是关注依靠食物链而生存的人类自身的健康。本期专题让我们的视线一同聚焦——— 相似文献

<正>转基因饲料(genetically modified feed,GMF)是指通过基因重组技术获得的基因改良生物加工而成的饲料(SN/T1201-2003)。目前,转基因农作物的商业化种植面积正在逐年增加,品种日益丰富,鉴于转基因作物潜在的风险性,世界各国纷纷制定相应的政策要求对用于饲料的转基因作物进行风险性评估,并且要求在饲料中的转基因成分不能超过一定数量,如欧盟要求饲料中的转基因成分不能超过 相似文献

When early people made their appearance, zoonotic infectious diseases were already waiting, but epidemic diseases did not appear in human history until people began to live in large numbers under conditions of close contact, mainly during the last 10,000 years. Disease has decimated urban populations, conquered armies, and disrupted society. The focus here is on (1) the plague of Athens and the Black Death; (2) smallpox, influenza, and rabies; (3) avian influenza prion diseases, and foot & mouth disease; and (4) emerging and re-emerging diseases. All have veterinary public health associations. In Athens, Greece, in 430 BC, when the Spartans ravaged the countryside, hordes crowded into Athens so that orderly movements, space in which to live, and adequate supplies of food became impossible. Crowding of any population fosters disease transmission; chaos and disorder enhance it all the more. Out of northern Egypt came a terrible plague from across the Mediterranean Sea. The identity of the plague of Athens remains unsure, but the well-considered conclusion is Rift Valley Fever, a mosquito borne, viral zoonosis. The Black Death, also called the Plague, raged in Asia for centuries. In 1347, the Black Death was brought by a ship out of Asia to Sicily. The scenes of devastation were repeated throughout Europe, with 90% or more of the people dying in city after city. Influenza, too, has been a cause of periodic human epidemics, but the great pandemic of influenza occurred in the last months of World War I. In the years of highest occurrence, more than half the world's population became clinically infected. If veterinary public health had been born earlier, it could have led to elucidating the epidemiology of influenza and the plagues of Athens, Europe, and Asia. In turn, smallpox had also caused continual tragedy. In 1796, Edward Jenner began to harvest pustules of cowpox from children or infected cows and inject them into susceptible children. In 1980, the World Health Organization declared that smallpox had been eliminated from the world. Rabies, though, still strikes terror. A number of animal diseases, broadly termed emerging and re-emerging diseases, need surveillance because they have the potential to impact human health. From late in 2003 to 2007, the highly pathogenic H5N1 influenza virus in poultry infected at least 121 people and caused 62 deaths in four countries. The prion diseases, too, all have very high numbers in concentrated contacts. To control these diseases, veterinary public health is essential, with diagnosis, epidemiological surveillance, clinical manifestations, and prevention as primary measures. 相似文献

On 26th of july 2007 a new case of bluetongue was notified in the Netherlands and on 2nd of august 2007 foot-and-mouth disease was diagnosed in Surrey, England, which raised the threat of having both infections simultaniously in one area. Bluetongue and foot-and-mouth disease have a different pathogenesis, but symptoms may resemble each other at a later stage of infection. The pathogenesis and possible clinical symptoms of both infections are discussed and illustrated with pictures. 相似文献
