Abstract :Nitrates are very toxic matters, which are stimulant methemoglobinemy and produce carcinogenic matters like nitrosoamines and nitrosoamides. The purpose of our research is to find out content of nitrates in different kinds of food products, which are produced in territory of the Republic of Macedonia and from import. Investigations were providing by an enzymatic method (reducing nitrates to nitrites) and after that, determining contents of nitrates spectrophotometricaly. All products are investigated by bioquant nitrate test. It was found that the medium values for nitrates in investigated products are less then maximum levels for nitrates in our country and less then regulation in WHO
