This article analyzes the reasons of temporary disability of laborers in Agro Industrial Complex, dealing with microbial content in industrial premises. Development and implementation of equipment for correction of microbial content level results in reduction of general morbidity rate and duration of temporary disability among laborers in Agro Industrial Complex. It will help to increase labor efficiency and decrease labor intensity of production. Biofilm resistance against antibacterial agents is a vital problem during disinfection treatments. Increase in bacteria survival potential and reduction in sensitivity to the substances eliminating them, results in need for increased dosing of the latter decreased efficiency of sanitation. This is a stimulus to develop alternative antibacterial compositions and methods of disinfection treatment. The basic difference of the suggested photodynamic treatment from the disinfection methods with application of antimicrobial preparations is the lack of resistibility to destabilizing oxidant – singlet oxygen. Before disinfection treatment, we determined total microbial air contamination according to the original method, providing a possibility to use air medium sampling of the total volume of indoor area. Experimental results have shown a decrease in total microbial contamination by a factor of 5.5 on average.
