Exposure To Flour Dust Makes Bakery Workers Vulnerable To Respiratory Diseases
A high prevalence of allergic sensitization and asthma was recently reported in South African supermarket bakeries. So researchers set out to conduct a detailed exposure assessment of these bakeries so as to provide the baseline for a broader intervention study.
A total of 211 full-shift personal samples were collected on randomly selected individuals within five different job categories in 18 bakeries. The samples were analyzed for particulate mass and specific flour dust allergens (wheat, rye, and fungal alpha-amylase). Exposure models were developed using job, bakery size, tasks, and specific ingredients used.
The researchers found bread bakers had the highest average (geometric mean) exposures. For alpha-amylase allergens, most samples were below the limit of detection for several occupational titles.
Elevated exposure to inhalable dust particulate as well as wheat and rye allergen concentrations were seen in large bakeries, bread baking, and in the use of cereal flours, while tasks such as confectionery work were negatively correlated with these exposure metrics.
Weighing tasks and use of premix products were associated with increased exposure to fungal alpha-amylase. A high correlation between particulate dust and wheat as well as rye was observed, with a much lower correlation between particulate dust and fungal alpha-amylase. Overall, a low proportion (39%) of bakery stores implemented various control measures to reduce dust exposures in the bakeries.

Now a correlation between flour dust and respitory diseases is confirmed what about people who were slapping dough in pizza shops for ten plus years?
