Hygienic assessment of working conditions and measures to preserve the health of workers in modern livestock complexes

Introduction. The impact on livestock workers of a complex of harmful industrial conditions is associated with health risks. The high level of general morbidity and an increase in the number of occupational diseases, as well as a decrease in labor productivity, emphasize the need to develop effective measures to improve working conditions and protect workers' health. The study aims to devise a set of measures designed to prevent the negative impact of hazardous working conditions on employees in modern livestock facilities. Materials and methods. Hygienic assessment of working conditions and analysis of the results of periodic medical examinations, survey data of employees of modern livestock complexes were carried out. Results. The study showed that concentrations of hydrogen sulfide, methyl mercaptan and ammonia in the workplace of livestock complexes exceed the maximum permissible concentration by 1.22–2.0 times, and dust by 1.62–18.5 times. The work of livestock breeders is associated with significant physical exertion. The working conditions of the animal care workers, the feed preparation shop, and the maternity ward were the most unfavorable (general assessment of working conditions 3.2). The highest incidence was recorded among employees of the feed preparation shop (76.4–76.8%). Limitations. The study is limited by the number of employees, the number of research objects, and the volume of data on the results of periodic medical examinations. Conclusions. The results of the study serve as the basis for the development of effective measures to improve working conditions and preserve the health of workers in modern livestock complexes and increase labor productivity. Ethics. The study was conducted in compliance with ethical principles, including voluntary participation of workers and confidentiality of their data.
