GM Food Animals Coming

چکیده
Heritable vs non-heritable modifications The Codex Alimentarius Commission of the United Nations is preparing guidelines for safety assessment of foods derived from recombinant-DNA animals [1], which is a sure sign that GM animal food is coming to our table. Codex distinguishes between heritable and non-heritable genetic modification of food animals. Heritable genetic modification involves genetic changes that persist in sperm and egg while non-heritable modification involves the introduction of modified genes such as vaccines into the somatic tissue of animals. Codex asks: “Are there specific food safety questions (e.g. with regard to types of vectors) that should be considered relative to the assessment of safety of food from animals containing heritable versus nonheritable traits?” We present an overview of heritable and non-heritable modifications, which are not as distinct as Codex thinks, and point to risks that have not been seriously considered. This article is base on a report we submitted to Codex [2], Genetically Modified Food Animals Coming, which contains all the detailed references.

Does GM work? Is GM technology too imprecise? Are GM genes more unstable than resident genes? Is it necessary to produce many transgenic plants to obtain an acceptable one? Could GM derived food be more toxic, more carcinogenic, or nutritionally less adequate when compared to other foods? And what is the potential for GM technology to produce foods with enhanced nutritional content or reduced t...
