Abstract
Introduction/ framework/ objectives “Baker’s Asthma” is a common type of occupational asthma in the bakery industry, related to the inhalation of allergens present in the work environment. It is a disease that produces high rates of absenteeism and temporary unfit for duty (sick leave). This study aimed to gather information about the presence of allergens present in the bakery sector that can develop occupational asthma, with the aim of potenciate the intervention by occupational health services. Methodology A literature review was carried out, including studies found in the online databases SciELO.Org, RCAAP, CINAHL, MEDLINE and MedicLatina, with research carried out between January and March 2022, with the keywords “Baker”, “Occupational Asthma” and “Allergens”. Full text articles published in the last five years, in English, Portuguese or Spanish, were defined as inclusion criteria. The protocol issue of this review is: “What are the allergens likely to trigger occupational asthma in the bakery area, as well as the preventive behaviors to be adopted?”. Results Baker’s asthma is one of the most common types of occupational asthma associated to exposure to flour dust and the allergens contained in it. Persistent exposure to airborne allergens may result in the initiation or worsening of asthma, as well as ocular and/or nasal symptoms. There is a strong relationship between occupational asthma and workers exposed to cereal flour dust, as well as some behaviors adopted by bakery workers as risk factors. The main allergens are those present in the dust of wheat, rye, barley, corn, oat and soy flours, as well as eggs, milk, buckwheat, sesame seeds, nuts and yeasts present in yeast as enhancers of the development of occupational asthma in the bakery sector. Conclusions The review of allergens and occupational asthma is important for the health of workers who continually inhale flour dust. It is important to identify the allergens that cause baker’s asthma, as it can help to improve the diagnosis and treatments of this disease and prevention programs. Workplace interventions, through the introduction of preventive measures (including individual and collective protection), health education and adequate training of workers, aimed at reducing exposure to allergens, contribute to reduce the incidence of occupational asthma.
