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 ...
Unraveling the occupational exposure to mycotoxins in a waste management settin...
Martins, Carla; Viegas, Carla; Eriksen, Elke; Graff, Pål; Afanou, Anani Komlavi; Straumfors, Anne; Twarużek, Magdalena; Grajewski, Jan; Kosicki, RobertIntroduction: Waste management represents an occupational setting where fungi are significant contaminants. This study aimed to assess the exposure of waste workers to mycotoxins through a human biomonitoring study. Methods: Thirty-three workers and 19 controls provided spot urine samples to determine 10 mycotoxins’ urinary biomarkers using liquid chromatography coupled with mass spectrometry. Risk characteriza...
Fungal and mycotoxins contamination in non-alcoholic beverages: the case of tea...
Viegas, Carla; Gomes, Bianca; Cervantes, Renata; Dias, Marta; Pena, Pedro; Oliveira, Filipe; Andrade, Ednilton Tavares de; Caetano, Liliana AranhaAgriculture constitutes one of the most sensitive sectors that could be affected by climate change. Among the xenobiotics contaminating agricultural crops, fungi and mycotoxins are the most challenging since their presence represents an economic burden due to crop loss and serious health effects related to animals and humans with severe repercussions. This study intends to characterize the fungal and mycotoxin ...
Assessment of waste workers occupational risk to microbial agents and cytotoxic...
Marchand, Genevieve; Wingert, Loïc; Viegas, Carla; Aranha Caetano, Liliana; Viegas, Susana; Twaruzek, Magdalena; Lacombe, Nancy; Lanoie, DelphineWorkers in the waste-processing industry are potentially exposed to high concentrations of biological contaminants, leading to respiratory and digestive problems and skin irritations. However, few data on the exposure of waste collection truck (WCT) drivers are available. The goal was to document the microbial risk of the waste collection truck (WCT) workers while in the vehicle cab. Long-period sampling using ...
Coffee production: an occupational setting where exposure to mycotoxins need to...
Viegas, Susana; Twaruzek, Magdalena; Kosicki, Robert; Oliveira, Filipe; Andrade, Enilton Tavares de; Viegas, CarlaCoffee production involves different processes until being available as a beverage involving several workers worldwide. 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 i...
Microbial assessment in a rare Norwegian book collection: a One Health approach...
Sequeira, Sílvia O.; Pasnak, Ekaterina; Viegas, Carla; Gomes, Bianca; Dias, Marta; Cervantes, Renata; Pena, Pedro; Twarużek, Magdalena; Kosicki, RobertMicrobial contamination poses a threat to both the preservation of library and archival collections and the health of staff and users. This study investigated the microbial communities and potential health risks associated with the UNESCO-classified Norwegian Sea Trade Archive (NST Archive) collection exhibiting visible microbial colonization and staff health concerns. Dust samples from book surfaces and the st...
Assessment of the microbial contamination in 'Do It Yourself' (DIY) stores: a h...
Dias, Marta; Gomes, Bianca; Pena, Pedro; Cervantes, Renata; Gonçalves, Sara; Carolino, Elisabete; Twarużek, Magdalena; Kosicki, Robert; Ałtyn, IwonaIntroduction: In “Do-It-Yourself” (DIY) stores, workers from the wood department are considered woodworkers. Given the health risks associated with woodworking, particularly from fungi and their metabolites, this study aims to assess microbial contamination and health risks for both workers and customers. Methods: The study was developed in 13 DIY stores in the Lisbon Metropolitan Area, Portugal. It employed a ...
Mycotoxins presence in woodworking environments from Portugal
Dias, Marta; Gomes, Bianca; Pena, Pedro; Cervantes, Renata; Twaruzek, Magdalena; Kosicki, Robert; Viegas, Carla; Viegas, SusanaWoodworkers may be exposed to a variety of chemicals and natural toxins that might be harmful to their health, including wood preservation products as well as metabolites produced by the microorganisms that grow on wood, such as mycotoxins. This study intends to characterize the mycotoxin's presence in two woodworking environments in Portugal.
