[Occupational asthma in food packers]

This report describes the case of a 26-year-old woman working in a fish-processing factory who developed bronchial asthma when transferred to the packing department. Various tests, including a specific bronchial challenge test, confirmed a diagnosis of occupational asthma. While polyvinyl chloride (PVC) appeared to be the causal agent in this case, the possible role of other etiological agents is also discussed. Although occupational asthma in food packers is rare, we nonetheless consider it important to recognize this type of asthma given the widespread use of PVC.
