Background/Objective: Poorly fitted work organization is high risk factors for developing work related musculoskeletal disorders (WMSDs). Bottling tasks require workers to maintain awkward posture while continually performing a machine paced repetitive motions throughout the work period thereby increasing risk for developing WMSDs. Determination of the association between such exposure to work-organizational factors and WMSDs can be the appropriate base for planning and implementing interventional program. This study was conducted among bottling workers of three bottling companies in Eastern Nigeria to investigate associations between work-organizational risks exposure and prevalence of WMSDs. 

Method: In this cross-sectional study, 301workers were purposefully recruited from bottling task workstations of 3 bottling companies in Enugu state, South East Nigeria. Standard Nordic musculoskeletal questionnaire (NMQ) was applied to study the prevalence of WMSDs while Organizational factor questionnaire (OFQ) was applied to evaluate work organization association with WMSDs. 

Result: There was a high prevalence (91.4%) of WMSDs among the bottling workers. Significant association existed between organizational risk scores and the prevalence of WMSDs in all the nine body parts studied (p=0.000). Moreover, all the domain of organizational factors was significantly associated with WMSD in at least one body part. Conclusion: Bottling task is a high risk occupation for developing WMSDs. These WMSDs are associated with work organization indices of work recovery cycles, task variability, work rate, workers’ control and mental stress as well as working posture adopted the workers. Therefore, intervention aimed at reducing risks and/or its effect on workers is essential.
