A study on the occurrence of genetically modified soybean and maize feed products in the Jordanian market [Genetik Olarak Modifiye Edilmiş Soya Fasülyesi ve Mi{dotless}si{dotless}ri{dotless}n Oluşturulmasi{dotless}]

There are concerns on the bio-safety of genetically modified (gm) products and indications on transfer of gm sequences from gm feed products to the food chain. thus the idea of this study was aimed to survey the status of occurrence of genetically modified soybean and maize feed products sold in the jordanian market by qualitative polymerase chain reaction based methods. genomic dna was extracted by cetyltrimethylammonium bromide (ctab) method from maize and soybean-based feed products. the molecular genomic analysis was designed to identify plant species specific genes of maize (zein) and soybean (lectin),expression control specific systems 35s promoter and nos terminator,and specific transgenic events. according to the results obtained in this analysis,100% of soy and 18.18% of maize used in production of feed were genetically modified and were unlabeled. the results of present investigation confirmed the occurrence of the genetic event hsp70 exon1/intron1 region of mon810 in the identified genetically modified maize feed products. the possibility of transfer of gm sequences from feed to food chain is discussed.
