“…Studies where mycotoxins have been identified and quantified along the various stages of the maize food chain have shown that maize grains for feed and food have the highest values of fumonisins [41]. Fusarium verticillioides and F. proliferatum have been described as the main fumonisin-producing species in Spain [42,43], with these mycotoxins the most frequently found contaminating ears in the three areas studied.…”

Maize expressing Cry1Ab insecticidal toxin (Bt maize) is an effective method to control Sesamia nonagrioides and Ostrinia nubilalis, the most damaging corn borers of southern Europe. In this area, maize is prone to Fusarium infections, which can produce mycotoxins that pose a serious risk to human and animal health, causing significant economic losses in the agrifood industry. To investigate the influence of corn borer damage on the presence of Fusarium species and their mycotoxins, Bt maize ears and insect-damaged ears of non-Bt maize were collected from commercial fields in three Bt maize growing areas in Spain, and differences in contamination were assessed. Additionally, larvae of both borer species were collected to evaluate their role as vectors of these molds. Non-Bt maize ears showed significantly higher presence of F. verticillioides, F. proliferatum, and F. subglutinans than Bt maize ears. For the first time, Fusarium species have been isolated from larvae of the two species. The most frequently found mycotoxins in ears were fumonisins, with non-Bt ears being significantly more contaminated than those of Bt maize. High levels of fumonisins were shown to correlate with the occurrence of corn borers in the ear and the presence of F. verticillioides and F. proliferatum.

“…(F. graminearum, F. culmorum, F. cerealis) is distributed worldwide and naturally found in cereals crops, particularly in maize [7]. According to the results obtained in 2020, the most prevalent mycotoxins globally were Fusarium mycotoxins, and 43 % of the samples tested were positive on zearalenone [8].…”

The paper presents the calibration and validation of a recent biomimetic-based fluorescent sensor system for the analysis of zearalenone (ZON) contamination in cereals. Methods. ZONspecific biomimetic sensing elements in a form of molecularly imprinted polymer (MIP) membrane were prepared by the in-situ polymerization method using cyclododecyl-2,4dihydroxybenzoate as a dummy template molecule and ethylene glycol methacrylate phosphate (EGMP) as a functional monomer. The detection is based on the fluorescence of ZON selectively adsorbed on the MIP membrane surface, which is registered by the spectrofluorimeter. Results. A biomimetic-based sensor system was calibrated for zearalenone analysis in cereal food products. The working range of the sensor system as well as its detection limit and the selectivity were examined. The calibrated biomimetic-based sensor system was successfully validated using maize and wheat flour with mean recoveries about 109 %. Conclusions. Calibration and validation studies of the novel ZON-selective biomimetic-based sensor system were successfully performed in cooperation with SE Ukrmetrteststandard. The standardized biomimetic-based fluorescent sensor system holds great potential to provide reliable prevention instrument against ZON contamination in cereals-based food products and feeding stuff.

“…Mycotoxin contamination in a variety of foods, feed and other commodities largely consumed by humans and animals, as well as the consequent serious threat to health, safety, global economy and society development has been a thorny issue in the world ( Cao et al, 2021 , Leite et al, 2021 , Liew and Mohd-Redzwan, 2018 ). Of 400 classified mycotoxins, ochratoxin A (OTA) is the most toxic member of ochratoxins produced by certain fungi species from the genera Aspergillus and Penicillium due to its confirmed hepatotoxicity, nephrotoxicity, teratogenicity, carcinogenicity, and genetic toxicity ( Huang et al, 2019 , Tao et al, 2018 ).…”
