Workers in microwave popcorn factories, coffee roasting facilities, and other food manufacturing plants are among those at highest risk of diacetyl exposure.
Occupational Exposure
Workers who inhale diacetyl vapors over prolonged periods may develop a condition known as bronchiolitis obliterans, a serious and irreversible lung disease. This condition is often referred to as “popcorn lung” due to its prevalence among workers in the popcorn industry. The symptoms of bronchiolitis obliterans can be severe and include chronic cough, wheezing, and shortness of breath, significantly impacting the quality of life.
How Does Diacetyl Cause Disease?
Research suggests that diacetyl causes disease by damaging the smallest airways in the lungs, leading to inflammation and scarring. This damage can result in the obstruction of airways, making it harder for oxygen to reach the bloodstream. The exact mechanisms by which diacetyl causes this damage are still under investigation, but it is believed that the chemical’s ability to form reactive compounds that damage lung tissue plays a critical role.
Symptoms of Diacetyl Exposure
The symptoms of diacetyl exposure can vary widely among individuals, depending on the level and duration of exposure. Mild symptoms may include coughing, wheezing, and shortness of breath, which can mimic those of common respiratory infections. However, as exposure continues, these symptoms can progress to more severe conditions.
Severe Symptoms and Conditions
- Chronic cough: A persistent cough that does not improve with treatment.
- Wheezing: High-pitched sounds while breathing out, indicative of obstructed airways.
- Shortness of breath: Difficulty breathing or feeling winded even when at rest.
- Chest tightness: Feeling of tightness or constriction in the chest.
- Fatigue: Unusual tiredness that does not improve with rest.
In severe cases, diacetyl exposure can lead to bronchiolitis obliterans, as mentioned earlier, which can significantly impair lung function and lead to disability.
