“…Due to their importance, maize and soybean are among the first crops to be genetically engineered and commercially used. There are several registered GM maize and soybean plants available worldwide (Aulrich et al, 2001;Tony et al, 2003;Greiner et al, 2005;Ujhelyi et al, 2008).…”

ABSTRACT. Despite the controversy about genetically modified (GM) plants, they are still incrementally cultivated. In recent years, many food and feed products produced by genetic engineering technology have appeared on store shelves. Controlling the production and legal presentation of GM crops are very important for the environment and human health, especially in terms of long-term consumption. In this study, 11 kinds of feed obtained from different regions of Turkey were used for genetic analysis based on foreign gene determination. All samples were screened by conventional polymerase chain reaction (PCR) technique for widely used genetic elements; cauliflower mosaic virus 35S promoter (CaMV35S promoter), and nopaline synthase terminator (T-NOS) sequences for GM plants. After determination of GM plantcontaining samples, nested PCR and conventional PCR analysis were performed to find out whether the samples contained Bt176 or GTS-40-3-2 for maize and soy, respectively. As a result of PCR-based GM plant analysis, all samples were found to be transgenic. Both 35S-and NOS-containing feed samples or potentially Bt176-containing samples, in other words, were analyzed with Bt176 insect resistant cryIAb gene- Genetic modified organism detection in feed samples specific primers via nested PCR. Eventually, none of them were found Bt176-positive. On the other hand, when we applied conventional PCR to the same samples with the herbicide resistance CTP4-EPSPS construct-specific primers for transgenic soy variety GTS-40-3-2, we found that all samples were positive for GTS-40-3-2.

“…Soybeans are a rich source of essential nutrients and high quality protein and are suitable for all ages (20). Soy and soy derivatives, such as protein isolates, concentrates and textured soy proteins, are widely used as ingredients in different food products due to their functional and nutritional properties (24). Soy protein products are also being used at an increasing rate in various processed meat products, which have become the major application of functional soy protein ingredients (1 0, 12).…”

“…in order to detect and determine the validity of the labelling systems, several countries have conducted surveys to monitor the presence of GMO (Partridge & Murphy 2004;Brod & Arisi 2007;Kyrova et al 2008;Ujhelyi et al 2008;Ari & Cakir 2008;Zilio Dinon et al 2010). In Serbia, over the past ten years have several studies dealt with the detection of GMOs in commercially available raw and processed foods (Maksimović et al 2002;Nikolić et al 2009;Taški-Ajduković et al 2009;Matić et al 2010;Miljuš-Djukić et al 2010).…”

Zdjelar G., Nikolić Z., Vasiljević I., Bajić B., Jovičić D., Ignjatov M., Milošević D. (2013): Detection of genetically modified soya, maize, and rice in vegetarian and healthy food products in Serbia. Czech J. Food Sci., 31: 43-48.The presence of genetic modifications was analysed in a total of 100 samples of non-labelled vegetarian and healthy food products. The basic raw materials in the samples tested comprised maize, soya, and/or rice. The screening of all samples was performed using the primers for CaMV35S promoter. The positive samples from this initial screening were further subjected to the analysis of specific transgenic material to determine the type of GMO present with subsequent quantification. Roundup Ready soya was found in eight samples, but its content was below the limit of 0.9%. None of the analysed samples of food products contained GM maize and GM rice. Considering that the investigated samples were imported mainly from EU countries, it can be concluded that the control of GMOs is carried out systematically and in accordance with the Serbian GMO Law.
