Abstract
The objectives of this study were to establish the impact of Fusarium culmorum infection and fungicide treatment on the occurrence of deoxynivalenol (DON), 3-acetyl deoxynivalenol, T-2 toxin, HT-2 toxin, nivalenol, fusarenon-X, diacetoxyscirpenol and zearalenone in wheat, wheat malt and wort (beer). The concentrations of these compounds were also measured in the germ/rootlets, spent grains and spent yeast because these are the most important by-products and are further used as food or feed additives. Two wheat genotypes were obtained from the Agricultural Institute in Osijek, Croatia. The Osk.110/09 genotype, the genotype more susceptible to Fusarium infections, and Lucija, the genotype less susceptible to Fusarium, were analysed in this research. Each genotype was treated in four different ways at the field: (A) control, (B) treated with fungicide Prosaro® 250, (C) inoculated with F. culmorum spores and treated with fungicide Prosaro® 250, and (D) inoculated with F. culmorum spores. All samples were malted and brewed according to standard procedures, products and by-products were analysed for the mycotoxins by using LC-MS/MS. Since the majority of trichothecenes are polar molecules, the water after steeping was also analysed with LC-MS/MS. Mycotoxin concentrations were lower in malt samples treated with the fungicide. Elevated mycotoxin concentrations were observed in samples of both genotypes exposed to F. culmorum. Fungicide treatment was observed to suppress mycotoxin production and accumulation. However, samples with notably high mycotoxin concentrations, especially DON, retained elevated mycotoxin concentrations throughout the entire beer production process, even after a six-month storage period. DON proved to be the most frequently occurring mycotoxin in all of the by-products. The highest concentration of this compound was found in the steeping water from sample D (Osk.110/09), at 20,326 μg/l, leaving the spent grains of this sample with no detectable levels of DON.

Abstract
A fast method using automated online solid-phase extraction (SPE) coupled to liquid-chromatography/high resolution mass spectrometric (LC-HRMS) detection for the determination of 12 mycotoxins in beer was developed and fully validated according to the performance criteria set in the European Union (EU) guidelines. Mycotoxin detection was achieved by full-scan HRMS with electrospray ionisation in positive ion mode within 13 min. No significant matrix interferences were observed. The lowest limits of detection (LODs) were achieved for emerging mycotoxins (beauvericin and enniatins) and ochratoxin A at levels between 0.01 and 0.02 μg/l, while the overall LODs were in the range of 0.01-0.30 μg/l. The elaborated method showed good performance in the analysis of beer samples with good linearity (R2>0.999), intra-day and inter-day precision at the levels of <12% and <13%, respectively, and recoveries in the range of 80-119%. Finally, this fully automated, sensitive, and reliable online SPE-HPLC-HRMS method was successfully applied for the analysis of 25 Latvian beers and the obtained results were comparable or even better than those obtained using the well-established Quick, Easy, Cheap, Effective, Rugged, and Safe, the QuEChERS, methodology.

Abstract
This review is mainly centered on beverages obtained from tropical crops, including tea, nut milk, coffee, cocoa, and those prepared from fruits. After considering the epidemiological data found on the matrices above, the focus was given to recent methodological approaches to assess the most relevant mycotoxins. Aspects such as singularities among the mycotoxin and the beverage in which their were found, and the economic effects and repercussions that the mycotoxin-tainted ingredients have on the beverage industry were pointed out. Finally, the burden of their consumption through beverages, including risk and health effects on humans, was addressed as well.

Abstract
A label-free optical biosensor for the fast simultaneous determination of three mycotoxins, aflatoxin B1 (AFB1), fumonisin B1 (FB1) and deoxynivalenol (DON), in beer samples is presented. The biosensor is based on an array of ten Mach-Zehnder interferometers (MZIs) monolithically integrated along with their respective broad-band silicon light sources onto a single chip. Multi-analyte determination is accomplished by functionalizing the sensing arms of individual MZIs with mycotoxin-protein conjugates. Assay is performed by pumping over the chip mixtures of calibrators or samples with a mixture of specific monoclonal antibodies, followed by reaction with a secondary anti-mouse IgG antibody. Reactions are monitored in real-time by continuously recording the MZI output spectra, which are then subjected to Discrete Fourier Transform to convert spectrum shifts to phase shifts. The detection limits achieved for AFB1, FB1 and DON were 0.8, 5.6 and 24 ng/ml, respectively, while the assay duration was 12 min. Recovery values ranging from 85 to 115% were determined in beer samples spiked with known concentrations of the three mycotoxins. In addition, beers of different types and origin were analysed with the biosensor developed and the results were compared with those provided by established laboratory methods, further supporting the accuracy of the proposed device.

Abstract
Contamination of food with mycotoxins and the associated possibilities of human intoxication is a serious problem in Africa. One of the most widespread mycotoxins is zearalenone (ZEN), which usually occurs in food of vegetable origin. On the other hand, information about ZEN in products of animal origin in African countries is extremely scanty. During the present study, levels of ZEN and its analogs: α-zearalenol (α-ZEL) and β-zearalenol (β-ZEL) were measured by high performance liquid chromatography (HPLC) with fluorescence detection in sun-dried kapenta fish - traditional Zambian food, as well as in the water of Lake Kariba - the main source of kapenta fish in Zambia. This study revealed that levels of ZEN in sun-dried kapenta fish fluctuated from 27.2 μg·kg-1 to 53.9 μg·kg-1, whereas the contamination of water from Lake Kariba with ZEN is rather minimally similar to the content of ZEN analogs in both kapenta fish and water. The obtained results have shown that sun-dried kapenta fish of Lake Kariba contain ZEN and may contribute to the exposure of consumers to this substance.

Abstract
Aspergillus fresenii and Aspergillus sulphureus produce ochratoxin A (OTA), which is a secondary metabolite of Aspergillus and Penicillium species, with nephrotoxic effects and potential carcinogenic activity. The aim of this study was to determine the effects of temperature (20, 30, and 37 °C), water activity (0.82, 0.86, 0.90, 0.94, and 0.98 aw), incubation period (5, 10, 15, and 30 days) on fungal growth, and OTA production by A. fresenii and A. sulphureus on Nyjer oil seeds. There was no fungal growth at 0.82 aw. The two fungal species were able to produce OTA from the fifth day of incubation from 0.86 to 0.98 aw and temperature 20 to 37 °C. Aspergillus fresenii produced the highest concentration of OTA (643 μg/kg) at 0.90 aw and 37 °C within 15 days, while A. sulphureus produced the highest level of OTA (724 μg/kg) at 0.98 aw and 20 °C within 10 days. The optimum water activity and temperature for the growth of both fungi were similar at 0.94 aw and at 30 °C. There was statistically significant difference between the levels of OTA production among the two fungi. Overall, A. sulphureus produced significantly higher levels of OTA (p < 0.05). Higher temperature (37 °C) and 0.90-0.94 aw were optimal for OTA production by A. fresenii. Our results show that Nyjer seeds can support the growth of A. fresenii and A. sulphureus and OTA production, and the two species had similar temperature and water activity requirements for growth but different requirements for OTA production on Nyjer seeds.

Abstract
A novel aptamer-based polyhedral oligomeric silsesquioxane (POSS)-containing hybrid affinity monolith has been prepared with a facile "one-pot" process simultaneously via "free radical polymerization" and "thiol-ene" click reaction, and used for on-line selective extraction and practical analysis to trace ochratoxin A (OTA). By using the ternary porogenic mixture composed of water/DMF/PEG, a homogeneous polymerization mixture with POSS chemicals, acrylate-based monomers and aptamer aqueous solution was obtained, and the copolymerization of POSS chemicals, polymer monomers and aptamer aqueous solution was systematically studied. Characterizations such as the morphology, FT-IR and fluorescence spectra, mechanical stability, dynamic binding capacity, cross-reactivity and selectivity of the resultant affinity monolith were also evaluated. Attributed to the porous monolithic structure and aptamer-based affinity interaction, acceptable selective recognition and recovery yields towards trace OTA were obtained. With a 5-fold volume enrichment, the limit of detection (LOD) and limit of quantitation (LOQ) of OTA in fortified beer samples were gained at 0.025 ng/mL (S/N = 3) and 0.045 ng/mL (S/N = 10), respectively. It could be competent for the sensitive measure of actual OTA residues in real beer samples. In comparison with the previously reported strategies containing common "sol-gel" chemistry, the proposed protocol to fabricating aptamer-modified POSS-containing hybrid affinity monolith showed a simpler preparation with acceptable selectivity and higher recovery to trace OTA.
