... it did not have bag filters installed in the cyclone dust-collection system, thereby allowing the release of large amounts of soybean dust into the air. High barometric pressure and low southeasterly to southwesterly wind speeds were registered on epidemic days appropriate weather conditions for moving air from the harbor to the city.

... Only castor-bean dust has been reported to be specifically causative of asthma epidemics.~~'° In New Orleans, the marked decline in asthma outbreaks has recently been attributed both to better socioeconomic conditions and the availability of better medical care for indigent patients with asthma, rather than to the disappearance of specific allergens or industrial chemical pollutants." In New York City, asthma-epidemic days were more likely to occur when susceptible persons spent more time indoors, suggesting an exposure to agents in the home.28 No relation was found, however, between outdoor air pollution and outbreaks of asthma,36 as in Barcelona. In Birmingham, a large asthma outbreak appeared to be caused by D2dimella ex~t~alis,5 but a more recent study could not confirm this hypothesis,37 and the question of the origin of the epidemic remains open.38 Soybeans have been identified as causing bronchial asthma, although infrequently so.
