Endotoxins in agricultural dusts.
Biodeterioration 6, the 6th International Biodeterioration Symposium, Washington, DC, August, 1984. Barry S; Houghton DR; Llewellyn GC; O'Rear CE, eds., Slough, UK, Oxford University Press, 1987 Dec; :312-315
In an effort to quantify the levels of endotoxins to be found in a variety of airborne agricultural dusts, samples of such dusts were collected and subjected to spectrophotometric modification of the Limulus amebocyte lysate gel test. Endotoxins were detected in dusts from cotton carding, grain handling, peanut shelling, poultry confinement and processing, and silo unloading operations. There were various levels of contamination in each of the dusts not only between industries but within those samples taken from the same operation. The lowest level of endotoxin in a dust was found in grain dusts at 0.4 nanogram/milligram (ng/mg) and the most highly contaminated dusts were from carded Texas cotton at 390.2ng/mg. Dusts from cottons carded similarly and at similar gravimetric dust levels varied markedly from 40.3 to 390.2ng/mg, due to the source of the cotton. The authors conclude that airborne dusts from various agricultural operations do contain gram negative bacterial endotoxin which can elicit respiratory pathophysiology on inhalation.
