As a result of the risk assessment process, to date, no biotech proteins in foods have<br />

been documented to cause allergic reactions, 816, 817, 818 though a number of studies have<br />

raised concerns of potential implications for allergic reactions. Despite several studies<br />

showing the potential for allergic reactions, or even specific cases of identified allergens,<br />

no commercially grown GE crop has been shown to cause allergic reactions owing to a<br />

transgenically introduced allergenic protein or a significant increase in the endogenous<br />

allergenicity of a crop. 819<br />

At present, it is clear that if and when a protein gene is derived from a source with a<br />

history of allergenicity, there is a reasonable certainty that the GE crop will be allergenic.<br />

Unfortunately, many studies have highlighted that the use of a gene from something that<br />

820, 821,<br />

is not allergenic will not guarantee that the GE crop will not possess allergenicity.<br />

822 In the absence of reliable methods for allergenicity testing, particularly the lack of<br />

good animal models, it is very difficult to completely assess if a GE crop may be<br />

823, 824<br />

allergenic or not.<br />
