- This study investigated musculoskeletal symptoms among fish trimmers (skinners and polishers) in a fish processing factory in Ghana. The methods used included administration of questionnaire, walk through observation, interview, task analysis and future workshop. All 50 female participants answered and submitted their questionnaires. Of the 11 operations performed by skinners only 1 was rated as low risk. Also of the 12 operations performed by polishers only 2 were rated as low risk. Neck side bending, neck flexion, prolonged standing, shoulder elevation, abducted arms, repetitious reaching forward and wrist deviation were observed in most operations. This corresponds with questionnaire results in which musculoskeletal symptoms were mostly prevalent in the neck, the shoulder, the low back, the wrist/hand and the knee regions. There was no significant correlation (p < .05) between musculoskeletal symptoms and age, working hours and length of service. Task redesign, workplace changes and worker training were suggested to improve the work.

Journal article (peer-reviewed)abstract
- This study investigated musculoskeletal symptoms among sanitation workers of a fish-processing factory. The methods used included administration of a questionnaire, walk through observation, interview, task analysis and future workshop. All 27 male participants answered and submitted their questionnaires. Of the 11 operations identified, all except one was considered safe. Bent back, bent legs, and heavy manual handling were observed to impose intolerable health risk on participants. This corresponds with questionnaire results in which musculoskeletal symptoms were mostly prevalent in the neck, the shoulder, the low back, the wrists/hands and the upper back regions. Poor psychosocial complaints were also made on the job. There was no significant correlation (p < .05) between musculoskeletal symptoms and age, working hours and length of service. Neither was any significant correlation observed (p < .05) between psychosocial work factors and musculoskeletal symptoms. Recommendations such as task redesign to eliminate high-risk elements in operations, workplace changes and worker training were suggested
