Cotton dust is often present in the air during cotton handling and processing. Cotton dust may contain many substances including ground-up plant matter, fiber, bacteria, fungi, soil, pesticides, non-cotton matter, and other contaminants that may have accumulated during growing, harvesting, and subsequent processing or storage periods.
Byssinosis, also called brown lung disease or Monday fever, is an occupational lung disease caused by exposure to cotton dust in inadequately ventilated working environments. [1] Byssinosis commonly occurs in workers who are employed in yarn and fabric manufacture industries. It is not thought that the cotton dust directly causes the disease and some believe that the causative agents are endotoxins that come from the cell walls of gram negative bacteria that grow on the cotton.
