Abstract
DURING an evaluation of the Limulus lysate assay procedure1–6 for the detection of Gram negative endotoxins, deionized water was found to be contaminated with endotoxins. Endotoxins were also present in samples of New Orleans tap water, which comes from deep levels of the Mississippi River. To appreciate the environmental distribution of endotoxins, studies were undertaken to compare the Gram negative endotoxin content of New Orleans water with that of other cities, as well as endotoxin distribution in various beverages and biological fluids.
