Health and safety consequences of shift work in the food processing industry

Abstract
Both a questionnaire survey and an evaluation of health and safety records were used to characterize the health and safety consequences of day versus afternoon, night and rotating shifts for approximately 1000 food processing workers. Relative to the day workers, the results indicated that those on shift work, particularly rotating and night shifts, showed greater adverse effects. These included poorer sleep, altered eating habits, greater alcohol consumption, greater incidence of sick absence and greater incidence of work-related injuries. Shift work was not related to self-reported health complaints or self-reported chronic disease states. The impact of shift work on sick absence and work-related injuries differed depending on worker sex, age and work tenure.
