Improvement of working conditions in agricultural production by reducing microbial contamination of its facilities

Abstract

Food production carried out by workers in a number of sub-sectors of the agro-industrial complex is inextricably linked with their identification with the sources of microbial contamination. Largely, this applies to the types of activity carried out in stationary facilities of the industry year-round or seasonally in some types of work. This is evidenced by the information provided in the article on the annual commissioning of new stationary facilities in the country for year-round keeping of animals, poultry, storage and processing of products in order to resolve issues of food supply of the population and raw materials for industry. As a rule, these are objects with permanent sources of microbial contamination. Workers engaged in industries with increased microbial contamination are susceptible to pathological processes caused by the chronicity of the infectious process and a decrease in the body's immune resistance. Microorganisms and their waste products found in the working area of a number of livestock, poultry, plant growing, fruit and vegetable (including greenhouse) industries lead to an increased susceptibility to infections, diseases, and, consequently, to an increase in the periods of temporary disability. Designing technical means and compiling disinfectant compositions to correct the level of microbial contamination leads to a decrease in the overall incidence rate and periods of temporary disability of workers, which will increase labor productivity and reduce the labor intensity of obtaining products. In this regard, an original model system was proposed in which the antioxidant properties of essential oils were studied by reaction with thiobarbituric acid under different experimental conditions (with and without heating). As a result of the experiments, it was found that heated anise essential oil and Morrison mustard plaster essential oil have the greatest anti-free radical activity. Devices for introducing essential oils into the respiratory tract have been developed. A method of phytodisinfection is proposed for air treatment, as a result of which the total microbial contamination in the premises is reduced on average by 3 times, the content of mold fungi - by 4 times.
