Rice (Oryza sativa L.) is one of the most important cereals in the world. Monitoring of the occurrence of unapproved GM rice on the Czech market is part of the "HYGIMON" study, which is addressed as part of subsystem 4 of "Total diet study" within the framework of "Environmental health monitoring system". The "HYGIMON" study is focused on the monitoring of food that do not meet the requirements for food safety according to EU  Regulation No. 178/2002. A total of 816 samples of rice, 240 samples of rice-based products and 192 samples of dishes containing rice were collected during the years 2008-2023.  The qualitative polymerase chain reaction (PCR) method was used to detect a specific DNA sequence. A total of 56 (4.5%) positive food samples containing GM rice were detected. The obtained results confirm that unauthorized GM rice is being detected in food products in the Czech market.

Keywords: genetically modified rice, “HYGIMON”, PCR
