    This research project is focused on analysing the ergonomic risk factors in the poultry sheds of the company "Avícola Pérez", in order to determine the main causes that generate musculoskeletal disorders and ailments, analysing the working conditions to identify the tasks that affect the physical deterioration of the workers. Implementing various research and evaluation methodologies, such as; the Kuorinka Nordic questionnaire that allowed us to determine the most affected body areas (neck, dorsal and lumbar area). The ISO TR 12295:2014 technical standard allowed us to determine that manual lifting of loads, repetitive movements and pushing or pulling loads are the ergonomic risk factors with the highest prevalence in the tasks performed by the workplace. The assessment of the ergonomic risk due to repetitive movements was carried out using the OCRA Check List method, showing an "Uncertain and Unacceptable" risk level in the poultry shed worker position. For the risk due to manual lifting of loads, the INSHT Technical Guide was used, showing a "Not tolerable" risk level in relation to the weight handled in a single lift and the total weight transported daily (PTTD) presented a "Tolerable" risk level. Finally, the risk from load pushing was assessed using ISO 11228-2:2019 in conjunction with the Snook and Ciriello Tables showing an "Unacceptable" risk level. Based on these results, a proposal for improvement is put forward that focuses on preventing, correcting and controlling the working conditions to which workers are exposed, through the use of intervention strategies and the development of instructions in order to safeguard the integrity and health of employees.
