Opis:: The safety and quality of animal feed are often unknown concerning the content of fungi and mycotoxins. Animal feed may be infested with fungi, leading to contamination with mycotoxins, which pose a potential risk to human and animal health. Currently, the feeding of pigs is mainly based on cereals and soy as protein components. In order to reduce the cost of feed production, other protein sources are used in addition to soy. To assess the health of pig feeds containing guar meal in their composition, a study was conducted to evaluate the presence of toxigenic fungi (culture and qPCR method) and mycotoxins (HPLC). Eight complete feeds produced on the farm containing locally produced feed materials including soybean meal and guar meal as protein components were investigated. The results of the mycobiome analysis showed that the tested feed mixtures were characterised by a high diversity of fungi, with saprophytic species clearly dominating. The qPCR analysis confirmed the presence of Fusarium and P. verrucosum fungi in the mixtures. Chemical tests of mycotoxin content confirmed the presence of Fusarium mycotoxins: DON, 3-AcDON, ZEA, T2 and OTA. Barley grain and guar meal were responsible for the contamination of the feed with the toxins DON, 3-AcDON, ZEA and OTA, while in the case of the T2 toxins, wheat grain and to a lesser extent the premix were responsible. The above correlations were confirmed by a correlation analysis that took into account the different levels of the feed components. Overall, it should be emphasised that the feeds were contaminated with mycotoxins to a low degree, which confirms their high quality. The storage conditions favoured the development of saprotrophic mycoflora and prevented the development of toxigenic species.

Opis:: The aim of this study was to assess the influence of Opisthorchis felineus infection on the nutritional quality and processing factors of fish meat, and to determine the resistance of O. felineus metacercariae colonizing fish muscles to various meat processing methods. The prevalence and severity of O. felineus infection were evaluated in three economically important fish species: Abramis brama (Linneus, 1758), Carassius auratus (Linneus, 1758), and Leuciscus idus (Linneus 1758). The fish came from the Birtaban-Shalkar lakes in the Akmola region of Kazakhstan. The microbiological quality of fish meat was evaluated using conventional methods based on the results of sensory analysis (n=34), analysis of proximate chemical composition, counts of mesophilic aerobic and facultative anaerobic microorganisms (CMAFAnM), coliforms, Salmonella spp., Listeria monocytogenes, and heavy metal concentrations (Pb, Hg, Cd, Cu, Fe, Zn, Mn, Ni, and Co) in the meat of infected and non-infected fish. Metacercariae were resistant to various meat processing methods. Opisthorchis felineus metacercariae were identified in all analyzed fish species. The meat of infected and control fish differed in proximate chemical composition. The content of heavy metals did not exceed maximum permissible limits. In comparison with non-infected fish, the meat of infected fish was characterized by a higher content of Fe (by 1.7%) and Zn (by 12.9%) and a lower content of Ni (by 5.5%), Cu (12.5%), Co (by 43.8%), Mn (by 59%), and Pb (by 37.3%). The content of Ca and Hg in fish meat was similar in both groups. Freezing, thermal processing, and salting destroyed 100% of O. felineus metacercariae in fish. Drying without pre-freezing was the only processing method that did not eliminate liver fluke larvae from fish meat.

Opis:: Decisions about how to remediate chemically degraded areas, including those contaminated with heavy metals, should take into account not only the restoration of soil quality but also other factors, such as an ecological risk. The aim of this work was to assess the ecological risk in an area historically contaminated with heavy metals originating from the metallurgical industry and pollution transported from outside the study area, using a multi-stage TRIAD procedure (considering different lines of evidence). This paper presents the results of chemical, ecotoxicological and ecological tests carried out on soils in the Sławków area in the Upper Silesian Industrial Region, one of the most severely polluted regions in Europe, especially contaminated with heavy metals. Conventional risk assessment methods based on determining the level of pollutants in the soil showed high content of heavy metals, especially of Cd, Pb and Zn. This level of pollution requires limiting land use and taking remedial actions. The inclusion of research based on biological methods has significantly expanded the possibilities of an assessment of the actual state of the environment. An environmental risk assessment based on the TRIAD procedure showed that the contamination has potentially fewer negative impacts on the environment and human health than demonstrated by a conventional assessment based on absolute limit values for metals.
