Objective: Work-related Musculoskeletal Disorders (WMSDs) have a multifactorial origin: work-related risk factors and individual factors (age, sex, anthropometric characteristics). The purpose of the current study was the risk assessment of upper limb-WMSDs of workers engaged in tasks of anchovies filleting and packaging in a fish industry considering the ergonomic evaluation and the painful symptomatology complained by employees of different age. The activities were analysed by the American Conference Governmental Industrial Hygienists (ACGIH) method, the Strain Index (SI) method, the Rapid Upper Limb Assessment (RULA) method as well as the Occupational Rapid Assessment (OCRA) checklist. Workers answered the Italian version of the Nordic Musculoskeletal Questionnaire (NMQ).
Results: The ACGIH method showed that packaging needs greater protection, while filleting requires ergonomic interventions. The SI showed a significant increasing risk for both tasks. The final score identified by RULA, for tasks of fish filleting and packaging, suggested a medium level of action, therefore were required additional observations. By OCRA checklist the final score for both tasks denoted a high risk.
