There is a list of dangerous flavors? Could you share the list please? I'd like to avoid them too. Thanks!
These are LorAnn's dangerous flavors, but the chemicals that produce the given dangerous flavor would be the same across all manufacturers, they just have it laid out nicely:

Ie, the recent scare of people dying from microwaved popcorn is over the fragrance used to scent the popcorn (butter smell... same used in ecigs, and no one actually inhales their popcorn...) is diacetyl ... well diacetyl is used in everything that has a butter (and maybe banana, and custards, anything that has been blended with a hint of buttery).
Well, here, from the horses mouth:

A number of employees exposed to FFCD have developed serious respiratory illness presenting with persistent dry cough, wheezing, shortness of breath upon exertion, and fixed airways obstruction on spirometry. Several employees have been diagnosed with asthma or bronchiolitis obliterans. Bronchiolitis obliterans occurs when small airways become inflamed and scarred, resulting in the thickening and narrowing of the airways. The symptoms and airways obstruction range from mild to severe, and do not improve when the employee goes home or on vacation. Because bronchiolitis obliterans is a rare disease, some employees may have been potentially misdiagnosed with asthma, bronchitis, emphysema, and/or pneumonia. The loss of pulmonary function associated with severe bronchiolitis obliterans is permanent and some patients have been placed on lung transplant waiting lists.
The National Institute for Occupational Safety and Health (NIOSH) has, and continues to investigate, the occurrence of severe lung disease in employees at microwave popcorn packaging plants (NIOSH, 2003) and flavorings manufacturing facilities (Kanwal and Kullman, 2007). NIOSH reported that medical tests of employees at microwave popcorn plants showed fixed airways obstruction, some cases consistent with bronchiolitis obliterans, and other respiratory illnesses such as occupational asthma. NIOSH concluded that the lung diseases identified in these microwave popcorn plant employees were likely due to exposure to butter flavoring chemicals (NIOSH, 2003; Kanwal, et al., 2006). NIOSH also described cases of fixed airways obstruction, including three cases consistent with bronchiolitis obliterans, among employees producing butter and vanilla flavorings containing diacetyl at a flavorings manufacturing facility (Kanwal and Kullman, 2007). NIOSH concluded that, in this facility, “
t is highly likely that exposures to diacetyl contributed to the occurrence of severe fixed obstructive lung disease...”, but that the role of other flavoring chemicals was unknown (Kanwal and Kullman, 2007).
