A NIOSH-indexed experimental study included barley among brewery materials whose dust extracts produced dose-related contractions in isolated guinea-pig tracheal tissue; this is an experimental airway-effect finding and not a workplace disease-rate estimate.

The effect of brewery dust extracts was studied using water-soluble extracts of dust obtained from brewery materials, including hops, barley, and brewery yeast. ... We suggest that brewery dust extracts cause a dose-related airway smooth muscle constriction by nonimmunologic mechanisms.
