It is established that the number of studies in certain years differs greatly in number. After all, the peak number of studies fell on 2012 (51985 samples), but in 2020 it was only 25.796 samples or 49.6 % to the peak level of studies. The highest percentage of pathogen isolation was observed in the period from 2013 to 2015, respectively 0.39, 0.48 % and 0.38 %. In 2016–2018, there was a decrease in the number of positive samples, respectively, the number of positive samples was 0.24–0.33 %, the lowest percentage in 2019–2021, the number of positive samples was minimal and amounted to 0.05 %, 0.22 % and 0.13 %. Thus, there is a clear trend of decreasing the amount of pathogen. The largest number of positive samples of biological material for salmonellosis in the period 2012–2021 was found in Sumy and Luhansk regions, 156 and 186 samples, respectively.
