(110,264 posts)have succeeded in restricting the research that's done and approving only the publication of favorable research.
And, since any GMO food is now considered safe by the FDA, unless proven otherwise (which can't be done unless approved by the producers), that means that allergenic elements from one species can be introduced into another -- and this wouldn't show up in any labeling.
It was proven long ago that allergens can be transferred through genetic engineering from one species to another.

CONCLUSIONS
The 2S albumin is probably a major Brazil-nut allergen, and the transgenic soybeans analyzed in this study contain this protein. Our study shows that an allergen from a food known to be allergenic can be transferred into another food by genetic engineering.
