Salmon allergen exposure, occupational asthma, and respiratory symptoms among salmon processing workers
Abstract Background This investigation was triggered by three cases of asthma—about 10% of the workforce—occurring in a salmon processing plant over a short period of time. The aim of the investigation was to characterize the work exposure of inhalable organic particles with personal measurements. R...
