Beyond 'substantial Equivalence'
ثبت نشده
چکیده
Whenever official approval for the introduction of genetically modified (GM) foods has been given in Europe or the United States, regulatory committees have invoked the concept of 'substantial equivalence'. This means that if a GM food can be characterized as substantially equivalent to its 'natural' antecedent, it can be assumed to pose no new health risks and hence to be acceptable for commercial use. At first sight, the approach might seem plausible and attractively simple, but we believe that it is misguided, and should be abandoned in favour of one that includes biological, toxicological and immunological tests rather than merely chemical ones.

Evaluation of Substantial Equivalence of salinity-resistant transgenic potato
Transgenic plants and their products are being developed day by day due to their improved characteristics, and it is necessary to evaluate the safety of these plants before releasing them. Hence, the importance of the issue of biosafety of transgenic plants and the use of their products has led the regulatory agencies to create some laws called substantial equivalence. based on that, the essent...
متن کاملBeyond Substantial Equivalence : Ethical Equivalence
The concept of substantial equivalence, introduced for the risk assessment of genetically modified (GM) food, is a reducing concept because it ignores the context in which these products have been produced and brought to the consumer at the end of the food chain. Food quality cannot be restricted to mere substance and food acts on human beings not only at the level of nutrition but also through...
متن کاملEquivalence criteria for the safety evaluation of a genetically modified crop: a statistical perspective
Safety evaluation of a genetically modified (GM) crop is accomplished by establishing its substantial equivalence to non-GM reference crops with a history of safe use. Testing hypotheses of equivalence rather than difference is the appropriate statistical approach. A necessary first step in this regard is to specify a reasonable equivalence criterion that includes a measure for discrepancy betw...
