• Description:
  Two former microwave popcorn production plant workers had pathology consistent with bronchiolitis obliterans. The prevalence of respiratory problems and airways obstruction among current workers were higher than expected. Exhaled nitric oxide (ENO) was measured in workers at risk for developing lung disease. One hundred thirty five workers completed a questionnaire, spirometry and ENO measurement. Workers with relatively high exposures (n= 107, mixing, microwave packaging, maintenance, and quality control) were compared to workers with low exposure from other areas of the plant (n= 28). ENO was lower in the 135 current workers (median 5.9 ppb) when compared to an external control group of 31 healthy never smokers (median 7.6 ppb) (p=0.001). ENO was lower in the high-risk group of workers (median 5.5 ppb) when compared to the low risk group (median 6.6 ppb) (p=0.03). There were no significant associations between ENO and current respiratory symptoms or lung function. However, after adjusting for smoking status, workers with current systemic symptoms were more likely than other workers to have a high ENO [chills OR: 7.8 (95% CI: 1.1-58.3); night sweats OR: 8.3 (95% CI: 1.1-64.6); fever OR: 4.0 (95% CI: 0.9-18.3)]. In this study of microwave popcorn workers, ENO was not useful for distinguishing between groups of workers with and without respiratory symptoms or lung function abnormalities. However, the association of ENO with systemic symptoms suggests that ENO might be useful in the study of inhalation fever or other inhalation syndromes. [Description provided by NIOSH]
