Description:In October 2015, the National Institute for Occupational Safety and Health received a management request for a health hazard evaluation at two coffee processing facilities regarding concerns about exposures to and health effects from diacetyl and 2,3-pentanedione during coffee roasting and grinding. In May 2016, we conducted a ventilation assessment, an industrial hygiene survey, and a medical survey at each coffee facility. The industrial hygiene surveys consisted of the collection of air samples and bulk samples of coffee for the analysis of diacetyl, 2,3-pentanedione, and 2,3-hexanedione. We used continuous monitoring instruments to measure total volatile organic compounds, carbon monoxide, and carbon dioxide in specific areas and during specific work tasks. The medical survey consisted of a health questionnaire and breathing tests. Facility A: Four of 12 full-shift personal air samples taken on six employees over two days showed air levels of diacetyl above the National Institute for Occupational Safety and Health's recommended exposure limit of 5.0 parts per billion, with a maximum concentration of 17.6 parts per billion. Two of 12 full-shift personal air samples showed air levels of 2,3-pentanedione above the recommended exposure limit of 9.3 ppb with a maximum concentration of 11.8 ppb. Facility B: Six of nine full-shift personal air samples taken on five employees over two days show air levels of diacetyl above the National Institute for Occupational Safety and Health's recommended exposure limit of 5.0 parts per billion, with a maximum concentration of 9.4 parts per billion. None of the full-shift personal air samples exceeded the recommended exposure limit for 2,3-pentanedione. We identified jobs where some work tasks resulted in relatively higher air concentrations of diacetyl than other tasks. Specifically, grinding roasted coffee beans, blending roasted coffee beans by hand, and weighing and packaging roasted coffee were associated with higher diacetyl levels. Nose and eye symptoms were the most commonly reported symptoms at both facilities. Some employees reported their nose and eye symptoms were caused or aggravated by green coffee beans, burlap bags, grinding coffee, or dust. Breathing trouble or shortness of breath were among the most commonly reported lower respiratory symptom at both facilities. One (9%) of eleven participants had high exhaled nitric oxide, a marker of allergic airways inflammation. Another participant had an abnormal spirometry test (one of 10 spirometry tests). We recommend training employees about work-place hazards and the use of respiratory protection. We also recommend a medical monitoring program to identify any employees who may be developing work-related lung disease (e.g., asthma, obliterative bronchiolitis) and to help management prioritize interventions to prevent occupational lung disease.
