Occupational exposure to airborne endotoxins during poultry processing during poultry processing operations was investigated. Dust samples were collected over a 2 week period from the shackling room of a poultry processing facility and were analyzed for concentrations of gram-negative bacterial endotoxins. All dust samples contained appreciable amounts of endotoxins. The mean time weighted averages for total dust endotoxin concentrations were approximately 918 nanograms per cubic meter (ng/Cum) at the entrance and about 634 mg/Cum at the exit of the shackling room. Mean endotoxin concentrations in respirable dust fractions were about 44.3 ng/cum at the entrance and about 33.6 ng/cum at the exit. The differences between entrance and exit concentration levels were not significant. The authors conclude that the potential exists for respiratory and systemic pathophysiology from the inhalation of gram negative biological endotoxins. Frequent testing of exposed workers is recommended.
