This review summarizes the available scientific literature on the detection of dietary DNA and protein in animal products and briefly discusses the implications of mandatory GE labeling for products from animals that have consumed GE feed.
…
Researchers have concluded that there is nothing to suggest that DNA from GE crops behaves any differently in the gastrointestinal tract of animals than non-GE counterparts. Absorption of dietary DNA across the intestinal wall appears to be a normal process that does not have adverse effects on food animals, regardless of whether the DNA is transgenic or endogenous.

Traces of dietary DNA and protein cannot be reliably detected in meat, milk, or eggs. Numerous studies have looked for the presence of rDNA and recombinant proteins in animal products, and the bottom line is that meat, milk, and eggs from animals that have consumed GE feed are analytically indistinguishable from those that have eaten non-GE feed. This makes mandatory labeling of such products misleading, because it would require labeling for something that was not discernible in the products. Given the wide trade and usage of GE livestock feeds globally, managing separate supply chains for indistinguishable animal products based on the GE content of the diet they consumed would be inefficient and expensive and would have no public health benefit based on available scientific data.
