BACKGROUND Exposure to airborne wheat allergen is a well-known cause of bakers' allergy and asthma. Airborne wheat allergen can be measured by enzyme immunoassays (EIAs) in extracts of inhalable dust samples, but only limited knowledge is available on the size distribution of wheat allergen-carrying particles. Recently, a new sampling medium, porous polyurethane foam, has been introduced for th...

OBJECTIVES To describe the levels of exposure to fungal alpha-amylase in British bakeries and flour mills, and to describe the relation between exposure to alpha-amylase and sensitisation to fungal alpha-amylase. METHODS 495 personal flour dust samples were taken in seven British bakeries and flour mills and analysed for alpha-amylase with an immunoassay. Workers at the sites were asked to fi...

Objectives—To describe the levels of exposure to fungal á-amylase in British bakeries and flour mills, and to describe the relation between exposure to á-amylase and sensitisation to fungal á-amylase. Methods—495 personal flour dust samples were taken in seven British bakeries and flour mills and analysed for á-amylase with an immunoassay. Workers at the sites were asked to fill out questionnai...

The present birth cohort study investigated whether or not childhood wheeze and asthma are associated with parental exposure to occupational sensitisers that cause asthma. Parental occupation, from the Avon Longitudinal Study of Parents and Children (ALSPAC), was related to wheeze, asthma, ventilatory function, airway responsiveness and atopic sensitisation in children aged 0-102 months. Occupa...

EVALUATION OF EXPOSURE TO FLOUR DUST AND RESPIRATORY COMPLICATIONS IN BAKERY WORKERS URMIA 2021

Baker’s asthma is one of the most common forms of occupational asthma. The increasing knowledge in exposure–response relations accumulated in recent years is important in the understanding of baker’s asthma. This development has made scientifically based prevention feasible today and baker’s asthma should not be regarded as an inevitable occurrence any more. In 1700 Bernardo Ramazzini described...

Investigation of Respiratory Exposure to Flour Dust in Workers Different Bakeries Urmia, Iran, 2021

Two laboratory workers, who spent a considerable time each day handling grain infested by the grain weevil (Sitophilus granarius), developed allergic responses to this insect varying from rhinitis and pruritus to marked asthma. These findings suggested that weevil protein present in mill dust could result in sensitization in those exposed continuously. A pilot study was therefore undertaken on ...
