Exposure-response relations of alpha-amylase sensitisation in British bakeries and flour mills.
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...

متن کاملDust and flour aeroallergen exposure in flour mills and bakeries.
As part of an epidemiological study among workers exposed to flour total dust and flour aeroallergen concentrations were measured with personal samplers over a workshift in three large bakeries and four flour mills and packing stations. In the bakeries geometric means for total dust concentrations ranged from 0.4 mg/m3 in the bread wrapping area up to 6.4 mg/m3 at the dough brake. The flour aer...
متن کاملExposure-response relations for work related respiratory symptoms and sensitisation in a cohort exposed to alpha-amylase.
AIMS To explore relations between exposure to fungal alpha-amylase and the risk of new work related respiratory symptoms or sensitisation. METHODS A prospective cohort study among 300 bakers and millers was followed up for a maximum of seven years. Exposure to alpha-amylase was estimated by air measurements and questionnaires and classified into three categories. Symptoms were recorded with a...
متن کاملWork related symptoms, sensitisation, and estimated exposure in workers not previously exposed to flour.
Findings are presented from the initial cross sectional phase of a cohort study of employees exposed to flour in bakeries or mills. Of 401 eligible workers in seven sites 344 (86%) were surveyed; symptoms assessed by self completed questionnaire, and sensitisation measured by the response to skin prick tests, were related to intensity of exposure both to total dust and to flour aeroallergen. Am...
