SAFETY ASSESSMENT OF FOOD-STUFF RAW MATERIAL AND FOOD PRODUCTS IN BURYAT REPUBLIC

Abstract

The aim of study was a hygienic assessment on sanitary and chemical, microbiological indicators of food and the food staples, realized in the territory of the Buryat Republic during 2008-2012. Preparation for processing of primary data and the subsequent statistical analysis made with Excel and the integrated package STATISTICA 6.0. Calculation of percent of tests of hygienic standards not conforming to requirements (%) on areas and as a whole on the republic is carried out. The specified sizes are determined as for separate years, and on the average for the period. To average values 95% confidential intervals (CI) are calculated. As significant deviations from the average levels the sizes which are going out of CI were considered. The performed result of assessment of the laboratory studies may testify that the stable high percent of the samples which don't accord to the normative in the sanitary-chemical indices is available at present. Using the cluster analyses allowed to reveal that according to the sanitary-chemical indices 52,4 % of all the regions in which the portion of the non-standard samples was found to be in the range of 95% confidence interval (CI) [6,5-9,0] % of the average level have formed the more numerous (1st) cluster. The second cluster consisted of the Zaigrayevskiy and Bichurskiy regions in which the statistically significant increase in the prevalence of the non-standard samples was revealed. In 5 regions and the capital of Republic (Ulan-Ude) in the third cluster the most significant percent of the samples which don't accord to the hygienic claims (CI [15,0-29,0] %) is continuously registered. The fourth cluster consisted of three regions situated in the northern part of Buryat Republic in which the non-standard samples are extremely rare revealed (CI [0,5-2,2] %). The samples portion which don't accord to the hygienic normative in the microbiological indices was found to increase by 1,4-fold compared to the 2009-2011 years and amounted 3,8 % in 2012 year. The analysis based on the territorial factor has shown that the high levels of the non-standard samples of the food products in the microbiological indices were found to be in the regions of the first cluster: Eravninskiy, Mukhorshibirskiy, Kabanskiy and Ulan-Ude (CI [5,1-7,8] %), the last revealed level is the regions of the third cluster: Zakamenskiy, Bichurskiy, Barguzinskiy, Kurumkanskiy, Okinskiy, Bauntovskiy (CI [0,10-0,24] %). The control of microbiological safety allowed to reveal the most significant, in epidemic relation, food products: milk, meat, fish products, the products of children's food as well as the poultry products.
