Genetically modified Roundup Ready soybean in processed meat products in the Kingdom of Saudi Arabia

This work was conducted to monitor the presence of Roundup Ready (RR) soybean in processed meat products in the Kingdom of Saudi Arabia (KSA). Seventy-two samples of processed meat products were collected from the Kingdom of Saudi Arabia (KSA) food market. DNA was extracted and analyzed by polymerase chain reaction (PCR) to amplify the soybean lectin gene, and screened by GMOScreen 35S/NOS test kit for qualitative detection of GMO varieties on food, feed, and seed to amplify both 35S promoter and NOS terminators that present in Roundup Ready soybean by PCR. The positive samples for Roundup Ready soybean (GMO) were subjected to real-time quantification of GMO using TaqMan real-time PCR. The results showed that all collected samples were positive for lectin gene and 45 samples out 72 samples were positive for Roundup Ready soybean. Twenty-three samples contained more than 10 g kg−1 GMO and 22 samples contained less than 10 g kg−1 GMO.
