Argument: Not all GM foods are detectable; labeling is inaccurate
"Labeling of GM foods." Think Quest: "Limitation of Detection Methods. Difficulties in detection of GM materials include:- At present, there is no standard analytical method on detection of GM materials. Not all GM food products can be identified by end-product analysis. Detection methods for highly processed foods e.g. soy lecithin are less sensitive and reliable when compared with raw or lightly processed foods, e.g. tofu (soy). For highly refined food items such as oil and sugar, it is impossible to detect the presence of any GM materials. There is no single test that can be used to detect all types of GM materials."
