• Description:
  The gram-negative bacterial endotoxin activity in airborne and settled dust samples from poultry and swine confinement areas was investigated. Airborne and settled dust samples were collected at six Midwestern United States swine and poultry confinement units, and were analyzed spectrophotometrically. The results were calibrated against the Food and Drug Administration reference Klebsiella endotoxin. All dust samples contained gram-negative bacterial activity. Concentrations from swine areas ranged from 4.51 to 11.81 micrograms per gram of settled dust, and from 4.77 to 47.74 micrograms per gram for airborne dust. Mean bacterial activity in settled dust from poultry areas was 11.39 micrograms per gram. The authors conclude that employees in the animal confinement industry are exposed to a potential occupational respiratory health risk. They suggest that animal feces rather than feed is responsible for these high endotoxin concentrations, since gram-negative bacterial activity in animal feed is less than 10 percent of that found in animal confinement areas.
