FCT:新研究证实转基因作物安全性

  1. 转基因

转基因作物是否安全,公众和科学界的观点存在巨大差异。代表公众的环保组织甚至将转基因和污染等同起来。法国的一项最新研究显示,转基因作物不太可能对健康构成威胁。 研究人员检查了24项长期和持续数代的抗虫和耐除草剂转基因作物研究,认为目前的证据显示,转基因作物的营养相当于同类的非转基因作物,可以安全地用于食品和饲料。 由于转基因是一种过程而不是一种产品,因此每一种转基因作物都必须单独的进行评估。

Assessment of the health impact of GM plant diets in long-term and multigenerational animal feeding trials: A literature review
Snell Chelsea, Bernheim Aude, Bergé Jean-Baptiste, Kuntz Marce, Pascal Gérard, Paris Alain, Agnès E. Ricroc
The aim of this systematic review was to collect data concerning the effects of diets containing GM maize, potato, soybean, rice, or triticale on animal health. We examined 12 long-term studies (of more than 90 days, up to 2 years in duration) and 12 multigenerational studies (from 2 to 5 generations). We referenced the 90-day studies on GM feed for which long-term or multigenerational study data were available. Many parameters have been examined using biochemical analyses, histological examination of specific organs, hematology and the detection of transgenic DNA. The statistical findings and methods have been considered from each study. Results from all the 24 studies do not suggest any health hazards and, in general, there were no statistically significant differences within parameters observed. However, some small differences were observed, though these fell within the normal variation range of the considered parameter and thus had no biological or toxicological significance. If required, a 90-day feeding study performed in rodents, according to the OECD Test Guideline, is generally considered sufficient in order to evaluate the health effects of GM feed. The studies reviewed present evidence to show that GM plants are nutritionally equivalent to their non-GM counterparts and can be safely used in food and feed.
