dc.description.abstractAbstract: "Among edible insect species, the house cricket (Acheta domesticus) has gained particular prominence in commercial insect farming and various food applications. Since insects intended for use as food or feed can bioaccumulate biological and chemical contaminants, rigorous safety monitoring is essential. The objective of this study was to assess the levels of trace elements, mycotoxins, and pesticide residues in commercially available house cricket powders (CP) sourced from six countries: England (CP1), Scotland (CP2), Vietnam (CP3), Thailand (CP4), Canada (CP5), and Poland (CP6). Trace elements (As, Cd, Cr, I, Ni, Se, Zn, Hg, Pb, and Sb) were quantified following microwave digestion of samples in nitric acid, using inductively coupled plasma mass spectrometry (ICP-MS). Mycotoxins, including aflatoxins B1 and B2, fumonisins B1 and B2, ochratoxin A, and trichothecenes such as DON, 3-AcDON, and NIV, were determined using chromatographic methods appropriate for each analyte group, including GC-MS and HPLC with fluorescence detection. Pesticide residues were analysed via liquid chromatography–tandem mass spectrometry (LC-MS/MS). The results indicated that the majority of CP samples exhibited low and relatively safe levels of the targeted con- taminants. However, elevated concentrations were observed in one sample, specifically arsenic (0.35 ± 0.01 mg/ kg d.m.) and boscalid residue (3.95 ± 2.1 mg/kg d.m.). These findings warrant particular attention to the rearing conditions, including feed quality and environmental factors, to minimize potential bioaccumulation risks in future production." (...)
