Detection of GM Soybean in Food Products by Simultaneous Employment of Three Pairs of PCR Primers - Nikolić, Taški-Ajduković, Jevtić i Marinković, 2009.

Abstract

Genetically modified soybean was explored in food samples, labeled as “non-GM” and unlabeled, using multiplex PCR and Real-time PCR techniques. In total 110 (2006) and 237 food samples (2007) containing soybean were analyzed. The 7% of the products were shown to consist of material derived from the Roundup Ready soybean in 2006 and 13% of the foods samples in 2007. The most of analyzed samples were correctly labeled, but ten of food products are demonstrated to contain material above the threshold levels for labeling of 0.9%. This is the first report of the validity of labels on imported food samples from different countries and uptake of GM food derived from soybean into the food chain in Serbia.

Conclusion

On the ground of the PCR measurements, 11% of the examinedfoods, deriving from the Serbian food market, proved to be GMOpositive and 3% of these samples contained RR soybean above0.9%. The product labels did not indicate the presence of GMOingredients in the food. On the basis of our results, it would beadvisable to control all of the imported ingredients and food prod-ucts by the authorities responsible for the food chain. The labelingrules should be informative to consumers, but should also take ac-count of the realities of international trade. The current uncer-tainty about ‘‘GM free” labeling are causing avoidable problems in the food industry.
