Listeria monocytogenes is a foodborne pathogen. A source of infection can be artisanal cheeses. Identification the species important for protection public health and food industry. This study aimed to examine cheeses presence L. effectiveness MALDI-TOF MS method in identification isolates. total 370 samples were examined. was found 23 cheese (6.2%). The reliability achieved by varied, vast majority isolates (27/32) identified only secure genus, probable level. showed that (i) occurrence at...

Artisanal cheeses can be sources of Listeria monocytogenes and cause disease in humans. This bacterial pathogen is a species diverse genotypic phenotypic characteristics. The aim the study was to characterize 32 isolates L. isolated 2014–2018 from artisanal cheeses. were characterized using whole genome sequencing bioinformatics analysis. cheese resolved four molecular groups: 46.9% them IIa (1/2a-3a), 31.2% IVb (4ab-4b-4d-4e), 12.5% IIc (1/2c-3c), 9.4% IIb (1/2b-3b-7). Two evolutionary...

This study aims to evaluate the microbiological status, pH, and water activity of European beaver meat establish its shelf-life safety. In this study, profiles minced obtained from carcasses beavers were investigated. Microbial evaluation chilled was performed within 24 h after hunting, on 7th day 14th day, frozen made during 11th week storage. Meat samples analysed for total viable count (TVC), psychrotrophic bacteria (PBC), Enterobacteriaceae (EBC), Escherichiacoli (EC), staphylococcal...

Heavy metals are introduced into water due to anthropogenic activities and can significantly affect an entire ecosystem. Due their close integration with the environment, fish a sensitive indicator of contamination. In addition, is important element in human diets, therefore, monitoring concentrations metallic contaminants meat particularly for food safety. This study aimed assess pollution ecosystems selected toxic heavy lakes Dratów, Czarne Sosnowickie, Syczyńskie. The concentration Pb,...
