GMOs ayaa mar kale ku jira jahwareer ka dib daabacaadda daraasadda Professor Gilles-Eric Séralini Sebtembar 19, 2012, oo muujinaya saameynta isticmaalka galleyda transgenic ee jiirka. Sabab wanaagsan oo lagu qiimaynayo xaqiiqada xaaladda iyo saamaynta suurtogalka ah ee noolaha hidde ahaan wax laga beddelay ee caafimaadkeenna.

Nafleyda hidde ahaan wax laga beddelay, ama GMOs, waa noolaha oo DNA-da lagu beddelay faragelinta aadanaha Thanks to injineernimada hidaha (farsamooyinka bayoolaji molecular isticmaalaya genetics si ay u isticmaalaan, dib u soo saarida ama wax ka beddelka genome ee noolaha). Farsamadani waxay markaa suurtogal ka dhigaysaa in hiddo-wadaha laga wareejiyo noole (xayawaanka, dhirta, iwm.) loona wareejiyo noole kale oo ka tirsan nooc kale. Waxaan markaa ka hadlaynaa transgenic.
