  1. Determinants of wheat antigen and fungal alpha-amylase exposure in bakeries.

    Article - En anglais

    The study's objectives were to measure flour antigen exposure in bakeries and define the determinants of exposure.

    Ninety-six bakery workers, employed in seven different bakeries, participated in the study.

    Two side-by-side full-shift inhalable dust samples were obtained from each study participant on a single occasion.

    The flour antigen exposure was measured as wheat antigen and fungal alpha-amylase content of the water-soluble fraction of inhalable dust, assayed via enzyme-linked immunosorbent assays.

    During the entire sampling period bakers were observed and information on 14 different tasks was recorded at 15-minute intervals.

    Other production characteristics were also recorded for each sampling day and used in statistical modeling to identify significant predictors of exposure.

    The mean alpha-amylase antigen exposure was 22.0 ng/m3 (ranging from below the limit of detection of 0.1 ng/m3 to 307.1 ng/m3) and the mean wheat antigen exposure was 109 mug/m3 (ranging from below the limit of detection of 1 mug/m3 to 1018 mug/m3).

    Regression models that explained 74% of variability in wheat antigen and alpha-amylase antigen exposures were constructed.

    The models indicated that tasks such as weighing, pouring, and operating dough-brakers increased flour antigen exposure, while packing and decorating resulted in lower exposures. (...)
