Food risks analysis and water safety

Water in its native form or as a component of various food products is the greatest and most frequently consumed part of daily nutrition. Scientifically justified criteria of its quality include epidemiologic and radiation safety, chemical harmlessness, and favorable organoleptic (aesthetic) properties. Over recent years in Russia more than 91.5 % population, and more than 96% in cities, have access to drinking water that conforms to all safety requirements. However, about 4-5 % of water samples taken from centralized water supply systems are not safe as per epidemiologic criteria. A drastic growth in chemical contamination of surface drinking water sources is another great concern. The authors focus on a modified procedure for detecting dextrose-positive bacteria that is, apart from being greatly informative, makes performance of sanitary-epidemiologic analysis much faster (approximately 1 day faster). It is confirmed that microbiologic control over blue pus bacilli occurrence is vital...
