Dermatoses--an occupational hazard in the canning industry

Despite the recognition that occupational dermatitis is extremely common, few data exist on the prevalence of skin disorders in South African industry. A cross-sectional prevalence study among 686 female workers in a canning factory in the western Cape showed high rates of dermatoses--in particular, chronic paronychia, intertrigo and dermatitis of the hands. A statistically significant association was found between exposure to 'wet work' in the industry and the prevalence of chronic paronychia and intertrigo. Age was also found to be associated with these dermatoses, irrespective of duration of service. The prevalence of dermatitis of the hands was increased among high-exposure workers, but not significantly. Dermatoses are an important occupational hazard in the canning industry, and there is a need for improved preventive measures.
