Comprehensive analysis of particulate matter, gaseous pollutants, and microbiol...
Furst, Leonardo; Cipoli, Yago; Galindo, Nuria; Yubero, Eduardo; Viegas, Carla; Gomes, Bianca; Cervantes, Renata; Nunes, Teresa; Feliciano, ManuelIn this study, indoor air quality was assessed in a store belonging to one of Portugal's largest commercial retail groups. A variety of methodologies were used, including gravimetric analysis for particulate matter (PM), optical monitors for real-time PM measurements, gas sensors and analyzers for CO2 and other gaseous pollutants, diffusion tubes for VOCs, and passive deposition for microorganisms. The average ...
Preliminary results concerning school staff personal exposure to microbial load...
Pena, Pedro; Cervantes, Renata; Dias, Marta; Gomes, Bianca; Riesenberger, Bruna; Marques, Liliana; Rodriguez, Margarida; Viegas, CarlaSchool environments are potential exposure scenarios to bioaerosols. Breading such contaminants can contribute to the development of respiratory infection. Most studies performed in schools regarding air quality focus on children’s health, neglecting the personal exposure of teachers and school staff. This study aims to provide a first insight into the personal exposure of teachers and school staff to bacteria ...
Levels of fungi in the air of poultry farms following different stages of birds...
Gomes, Bianca; Dias, Marta; Pena, Pedro; Cervantes, Renata; Rodriguez, Margarida; Marques, Liliana; Riesenberger, Bruna; Carolino, ElisabetePoultry production intensification might influence microbial development. Concerning fungal assessment, despite the limited number of studies, several fungi have already been found in poultry pavilions. Occupational health specialists frequently overlook worker safety and biological risk assessment due to a lack of systematic knowledge regarding the agents involved. Consequently, workers, exposed to organic dus...
Sampling protocol to assess Aspergillus section fumigati in woodworking environ...
Dias, Marta; Gomes, Bianca; Pena, Pedro; Cervantes, Renata; Rodriguez, Margarida; Riesenberger, Bruna; Marques, Liliana; Ribeiro, Edna; Viegas, CarlaAzole fungicides are commonly used in sawmills to protect wood against the wood-destroying basidiomycete fungi. Azole-resistant Aspergillus section Fumigati has previously been identified in these environments. Here we aimed to establish a sampling protocol to efficiently isolate Aspergillus section Fumigati in woodworking environments. The sampling campaign was conducted between December 2022 and November 2023...
Boosting knowledge on occupational exposure to microbial contamination in Portu...
Dias, Marta; Gomes, Bianca; Pena, Pedro; Cervantes, Renata; Rodriguez, Margarida; Riesenberger, Bruna; Marques, Liliana; Carolino, ElisabeteIntroduction: Wood industry workers face health risks due to exposure to microorganisms and their metabolites. This study aimed to characterize seasonal microbial contamination, antifungal resistance, mycotoxins, cytotoxicity, and particulate matter in Portuguese carpentries, to reduce exposure and promote safe working conditions. Methods: Conducted in six carpentries in Lisbon, Portugal, the sampling strategy ...

Tackling fungal contamination for safer farming
Gomes, Bianca; Dias, Marta; Cervantes, Renata; Pena, Pedro; Twarużek, Magdalena; Kosicki, Robert; Viegas, Susana; Viegas, CarlaBiosafety measures are essential for maintaining animal health and workplace safety in poultry production. Poultry farm environments favor fungal growth, yet information on fungal contamination and associated health risks remains scarce. This study aimed to assess fungal and mycotoxin contamination in poultry pavilions (PP) during the poultries' growth cycle. Sampling was conducted during winter in 14 PP, Portu...
From farm to food: the overlooked impact of mycotoxins in poultry feed
Gomes, Bianca; Dias, Marta; Cervantes, Renata; Pena, Pedro; Twarużek, Magdalena; Kosicki, Robert; Viegas, Susana; Viegas, CarlaThe occurrence of mycotoxins in poultry feeds is a primary problem worldwide due to their carcinogenic, mutagenic, and reprotoxic effects. This secondary metabolite generated by fungi can compromise animals' health and productivity. Monitoring mycotoxin exposure is crucial, as fungi are not reliable indicators of mycotoxin presence. This is partly because mycotoxins can remain in the environment long after the ...
Poultry farms as reservoirs of azole-resistant fungi: occupational health risks...
Gomes, Bianca; Dias, Marta; Cervantes, Renata; Pena, Pedro; Carolino, Elisabete; Caetano, Liliana Aranha; Viegas, Susana; Viegas, CarlaThe intensification of poultry farming has raised concerns regarding microbial contamination and antifungal resistance, particularly involving Aspergillus fumigatus, a key pathogen presenting clinical relevance. This study aims to present the first in-depth evaluation of environmental conditions, airborne particles, microbial contamination, and fungal resistance to azole drugs in poultry farm environments. A mu...
Poultry farms as a One health priority for Aspergillus section Fumigati surveil...
Gomes, Bianca; Dias, Marta; Pena, Pedro; Cervantes, Renata; Viegas, Susana; Viegas, CarlaIn poultry production environments, particulate matter (PM) is considered one of the harmful air pollutants. Considering potential biological pathogens, the genus Aspergillus in particular, Aspergillus fumigatus, is a widely recognized human and animal pathogen. Hot-humid farm environments could contribute to the proliferation of these fungi. Therefore, poultry production workers, besides animals, may be at a h...
