Chicken bedding material may be an underestimated source of pathogens. Currently, there is a lack of information concerning the impact of the bedding material used on fungal development. We aimed to characterize fungal exposure in poultry facilities during birds growth cycle.info:eu-repo/semantics/publishedVersio

Mycotoxin exposure may occur in this occupational setting since coffee beans are frequently contaminated with these fungal secondary metabolites due the crop infection by toxigenic fungi that commonly infect the plant during the various production stages. A study was developed in two milling industries located in Brazil aiming to evaluate workplace contamination with mycotoxins.info:eu-repo/semantics/publishedVersio

In occupational studies focusing on microbiological contamination in poultry farms, air sampling is typically the only sampling method used. To better understand the relationship between factors influencing microbial contamination and adverse health effects, data regarding the amount, composition, and risk category of the common microorganisms are needed. This study intends to apply a multi-approach sampling protocol and corroborate the importance of its application for a wider microbial characterization.info:eu-repo/semantics/publishedVersio

To assess that exposure, the sampling strategy is crucial to accurately determine the possible health consequences for workers and gather data on microbial viability. It has been suggested that using scoring rubrics in performance assessments has several benefits, such as enhanced scoring uniformity, allowing correct evaluation of difficult abilities, and learning promotion. This evaluation aims to generate a score that will offer current data to determine the best sampling technique for occupational exposure to fungal contamination.info:eu-repo/semantics/publishedVersio

It has been found in different occupational environments, such as sawmills and waste sorting. Its cryptic species show intrinsic resistance to several antifungals. Resistance in A. fumigatus is emerging due to selective pressure caused by the prolonged use of azoles. It is often associated with mutations in the Cyp51A gene. The fungal priority pathogens list (WHO), includes A. fumigatus with critical priority. Further analysis to identify potential resistance mechanisms and mutations is needed. Objective: This evaluation aims to offer a protocol for mutation detection in Aspergillus section Fumigati isolates. It will contribute to the development of guidance that can support future occupational exposure assessments.info:eu-repo/semantics/publishedVersio

Workers in the sawmill industry may be exposed to wood derivatives, microorganisms, and their products. Wood products can cause health effects such as decreased lung function, bronchial hyperresponsiveness, and various respiratory disorders. Exposure to wood dust infected with microorganisms, particularly fungi, can lead to allergic alveolitis and asthma in woodworkers. There is a knowledge gap in the field of microbial occupational exposure assessment in sawmills. The importance of an accurate assessment and risk management should be emphasized. This study aims to define a protocol that allows a proper assessment of microbial contamination in woodworking environments.info:eu-repo/semantics/publishedVersio
