Allergenicity
As a matter of principle, the transfer of genes from commonly allergenic
organisms to non-allergic organisms is discouraged unless it can be
demonstrated that the protein product of the transferred gene is not
allergenic. While foods developed using traditional breeding methods are
not generally tested for allergenicity, protocols for the testing of GM
foods have been evaluated by the Food and Agriculture Organization of
the United Nations (FAO) and WHO. No allergic effects have been found
relative to GM foods currently on the market.
