Occurrence of genetically modified food in Egyptian food market [electronic resource].

Includes references.

The use of genetically modified organisms (GMOs) as food or products is becoming widespread. The European Union has implemented a set of very strict procedures for the approval to grow, import and/or utilize GMOs as food or food ingredients. Recently, DNA-based techniques became very common for the detection of GMOs in food products. For rapid and easy detection of GMOs, polymerase chain reaction (PCR) screening methods, which amplify common transgenic elements, are applied in routine analysis. In this study, A total of 140 maize, maize products, soy and soybean products were collected from the Egyptian food market during 2005/2008. DNA based methods were used to detect the genetic modification in proportion above 1% in all samples. Maize samples were analyzed to detect the presence of maize line Bt 176, Bt 11, Mon 810, maize line T25 and starlink maize. On the other hand soy samples were analyzed to detect the genetic modified soybean line Roundup Ready, The results indicated that 18.57 % from maize samples were positive for maize line Bt176, 15.7 % positive for maize line Bt11, and 12.85 % positive for maize line StarLink™. On the other hand, 25.7 % from soybeen samples positive for the presence of Roundup Ready soy bean.
