This case involves a 36 year old non-smoker who worked in a factory producing food flavourings for potato crisps. He developed exertional breathlessness associated with fixed airway obstruction shortly after an uncharacteristically high exposure to the food flavouring chemical diacetyl. Unfortunately, even though he was removed from further exposure to this agent, his symptoms and spirometry did not improve.

This case study explores the applicability of transcriptome data to characterize a common mechanism of action within groups of short-chain aliphatic α-, β-, and γ-diketones. Human reference data indicate that the α-diketone diacetyl induces bronchiolitis obliterans in workers involved in the preparation of microwave popcorn. The other three α-diketones induced inflammatory responses in preclinical animal studies, whereas beta and gamma diketones in addition caused neuronal effects.

Article Synopsis
- Exposure to diacetyl and related chemicals in flavoring and popcorn production has been linked to serious respiratory issues, including obliterative bronchiolitis, as shown in both workers and laboratory animals.
- In coffee processing facilities, increased exposure to these chemicals has been observed, particularly among workers who grind roasted coffee beans.
- Implementing engineering controls, like ventilated enclosures around grinding equipment, significantly reduced harmful chemical concentrations in the air, highlighting effective measures to protect worker health.

The case definition of inhalational constrictive bronchiolitis (CB) has changed over the generations. We identify changes in the description of this illness over time associated with different exposures and present the natural history of CB in a case attributed to military burn pit exposure. The initial descriptions of this disease began with nitric acid spills and silage exposures.

Diacetyl (CHO) is a toxicant commonly found in electronic cigarettes (e-Cigs) as a flavoring component and an enhancer of e-juices. Lung injury in current and former workers in popcorn manufacturing suggests a possible association with diacetyl inhalation exposure. Although the number of e-Cig users continues to rise steadily among the teens and adults, the potential risk of pulmonary disease has not been characterized.
