The purpose of the paper is to show how the soybean meal is tested for the GMO content after the acceptance in the feed concentrate factory, arriving from Brazil and Hungary. After acceptance of the soybean meal the analysis for the protein and moisture contend is made and the average monthly sample is sent to an external laboratory for testing for GMO content. According to the regulations the GMO content must not exceed 0,9% and is determined by the PCR (polymeraze chain reaction) method. Ten analyses for GMO content have been performed by establishing the influence of the origin on the GMO content and the average percentage of GMO in the soybean meal. In two cases the results of analyses of the soybean meal were negative, which means that the soybean meal did not contain any GMO; in eight cases the test was positive, but none of them exceeded the sill of 0,9%. Irrespective of the supplier or origin the average percentage of the GMO in soybean meal is approximately identical, i.e., 0,3%. Only the soybean meal, arriving from Brazil, has a smaller percentage of the GMO, i.e., 0,22%. It means that not the supplier, but only the origin has an influence on the percentage of the GMO in soybean meal. On the average, the soybean meal coming from Hungary contains more GMO, i.e., 0,3%, than the soybean meal coming from Brazil, which contains 0,22%. The research showed that most soybean meals were genetically modified, but in no case the limit prescribed by the regulations, i.e., 0,9%, was exceeded.
