Objective: To investigate the incidence of occupational asthma induced by occupational exposure to detergents and spices.
Methods: The occupational history, case data, and results of auxiliary examinations were collected from patients with asthma induced by occupational exposure to detergents and spices and submitted to the expert group for diagnosis of occupational diseases to obtain the diagnostic results.
Results: Both patients with asthma were exposed to asthmogenic substances in the working environment and developed the symptoms of asthma after a certain latency period. In case 1, the patient had positive results from bronchial dilation test and peak expiratory flow test; in case 2, the patient had positive results from allergen skin prick test for spices and essence and allergen bronchial provocation test. Therefore, the possibility of asthma induced by occupational factors could not be excluded.
Conclusion: Occupational exposure to detergents and spices can induce occupational asthma.
