Abstract

In the meat industry, operations on slaughter lines entail a high physical workload that compromises workers' occupational health and quality of life. This study evaluates the impact of dysergonomic risks at the Municipal Slaughterhouse in Riobamba, Ecuador, where tasks associated with the slaughter of cattle, pigs, and sheep involve prolonged standing, awkward postures, intensive use of cutting tools, and heavy load handling. To characterize occupational exposure and propose control measures, a mixed-methods approach (quantitative and qualitative) was applied, integrating the OCRA and Job Strain Index (JSI) ergonomic methods and complementing them with symptom surveys administered to workers. The results revealed a 72% prevalence of musculoskeletal disorders (MSDs), manifesting primarily as chronic ailments and disabilities that affect the facility's productivity and operational safety. It is concluded that the severe presence of dysergonomic factors necessitates an urgent, comprehensive intervention based on the implementation of Safe Work Procedures (SWP), job rotation, active break programs, workstation redesign, and continuous training. Furthermore, extending the assessment to other risk factors (physical, chemical, and biological) is recommended to ensure a safe and holistic work environment.
