Airborne Microorganisms in Cotton Mills over Several Years

Janet J. Fischer, Karin K. Foarde, John Neefus


 
ABSTRACT

The mill environment has been changing. This paper documents the stability of the environment as measured by levels of airborne GNB, LPS, and dust over a period of two weeks during which mill conditions did not change. Five years of data on commercial mills document the gradual decrease in levels of airborne GNB, LPS, and dust as conditions change (improvements are made in the mills) . The mills are divided (for comparison purposes) into those processing >50% cotton, those processing <50% cotton, and those processing synthetic fibers. They are also grouped as to whether the carding and spinning areas are separate or together.
