The purpose of the research is the analysis of the incidence rate of population and detection of characteristics of animals’ infection by Trichinella activator in Novosibirsk region. Materials and methods. Research of epidemical situation on trichinellosis have been conducted based on analysis and data systematization of Authority of Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing around Novosibirsk region about trichinellosis incidence rate of people during 2003–2016, as well as on the materials introduced in National reports "About the status of sanitary and epidemiological welfare of the population of Russian Federation and Novosibirsk region” for 2003–2016. The following criteria were used for evaluation of epidemical situation on trichinellosis – incidence rate parameter, long-time average annual incidence rate parameter, as well as grow rate parameter (lowering) incidence rate was calculated. Monitoring of epizootic situation have been conducted using data of Authority of veterinary science of Novosibirsk region.Results and discussion. Surveillance studies certify that human and animals’ trichinellosis was registered in Novosibirsk region practically annually over the last 16 years. Dynamics of people incidence rate on trichinellosis in Novosibirsk city and region significantly overlap. Superior limit of diseased people was marked in 2004 and the inferior limit was marked in 2008. The incidence rate of population of Novosibirsk region varied from 1.93 to 0.04 and was average 0.4 per 100 thousand of population. Average annual rate of growth/ lowering of incidence rate over 5 year period show clear tendency to incidence rate of population. In the disease distribution portion of the rural population is 63.6%. The pig and the badger are the most dangerous among domestic and wild animals of Novosibirsk region in respect of human infection by Trichinella, trichina larvae were recorded in their muscular tissue in 71.1% and 15.8% cases.
