In the article, there were shown the experimental researches describing the influence of parameters of electrical ozonization of the premises of egg storehouse at concentration of ozone in 20 mg/m3 on survival of following stimulants: S. aureus, S. choleraesuis, P. vulgaris, E. coli. There was determined that ozone has an ability to detain the growth of fungi on biological substrates as well as it slows down the process of mould appearance on egg shell surface even at 90% of relative moisture. The aim of scientific experiment is obtaining of regression models of influence of parameters of electrical ozonization on main sanitary-model microorganisms contaminating the shell of incubation eggs. To assess the effectiveness of ozonization there was adopted the parameter of survival for four main pathogenic microbiological test-objects which predominate on egg shells. The correlation and regression analysis of factors and determination of value of equation coefficients there were conducted using the program STATISTICA 6.1. The correlation analysis was made by the method of Pierson. Approximation was obtained by the method of polynomial. On the results of researches there was determined that the least survival of present test-bacteria at concentration of ozone in 20 mg/m3 is achieved at exposition 84 minutes. So, the rational time the electrical technological process of ozonization of egg storehouse of poultry factories presents the sum of obtained exposition and time of regulation
