“…These fi ndings signifi cantly set apart this sampling site from the rest and point to a strong correlation with ZEA levels in maize, which was grown in the nearest vicinity of this collection point. As known, maize is the cereal with the highest recorded concentrations of ZEA (25,26).…”

The aim of this study was to establish a relation between zearalenone contamination of crops in the Polish province of Wielkopolska and its occurrence in aquatic ecosystems close by the crop fi elds. Water samples were collected from water bodies such as drainage ditches, wells, or watercourses located in four agricultural areas. Moreover, control water samples were collected from the Bogdanka river, which was located outside the agricultural areas and near an urban area. Cereal samples were collected in the harvest season from each agricultural area close to tested water bodies. Zearalenone (ZEA) was found in all water and cereal samples. The highest concentrations were recorded in the postharvest season (September to October) and the lowest in the winter and spring. Mean ZEA concentrations in water ranged between 1.0 ng L -1 and 80.6 ng L -1 , and in cereals from 3.72 ng g -1 to 28.97 ng g -1 . Our results confi rm that mycotoxins are transported to aquatic systems by rain water through soil.

“…It is a polar organic compound of the type B trichothecenes [66]. It is usually produced by Fusarium culmorum and Fusarium graminearum [67].The contamination of economically important cereals represents a great problem in Europe, Asia and America since it occurs in the field more frequently than in the warehouse [68]. Since this mycotoxin is stable during the production process, it can often be found in processed food.…”

Food contamination is one of the major problems in food distribution. Microorganisms and their metabolites are the most common food contaminants. This review consolidates the reported food contamination cases in the Republic of Serbia. Mycotoxins were stated as the most common contaminants in various foods. Among them mycotoxins like zearalenone, aflatoxins, fumonisins, and deoxynivalenol were the most frequently detected. Also, the contamination caused by the presence of various microorganisms like L. monocytogenes, E. coli, Salmonella spp. and S. aureus was reported in high frequency. The microbial contamination was usually detected in meat and dairy products. Although heavy metals were detected in some products, in most cases their concentrations were in accordance with the legislation. A higher level of Pb and Hg was stated only in a few samples of tea, milk and fish. The constant analysis, control and prevention are needed at all levels of the production in order to compile the safety requirements and international legislation.

“…Similar to ochratoxin, the analysis of zearalenone by using high-performance liquid chromatography in combination with fluorescence detection is widely discussed in literature [34][35][36][37]. During the execution of the fluorescence step, an excitation wavelength of 254, 274, 275 or 356 nm is often used, while the detection of the fluorescence signal occurs at 440, 446 or 470 nm.…”

The presence of mycotoxins in food products is a major worldwide problem. Nowadays, mycotoxins can only be detected by the use of sample-based chemical analyses. Therefore, we demonstrate the use of one-and two-photon-induced fluorescence spectroscopy for the non-destructive detection of mycotoxins in unprocessed food products. We first explain our optical set-up, which is able to measure the localized oneand two-photon-induced fluorescence spectra. Following, as a case study, the detection of aflatoxin in maize kernels is discussed. We present our research methodology, from the characterization of the fluorescence of pure aflatoxin, to the study of the one-and two-photon-induced fluorescence spectra of maize kernels and the development of an optical detection criterion. During both one-and two-photon-induced fluorescence processes, the fluorescence of the aflatoxin influences the intrinsic fluorescence of the maize. Based on the fluorescence spectrum between 400 and 550 nm, a detection criterion to sense the contaminated kernels is defined. Furthermore, we successfully monitored the localized contamination level on the kernel's surface, showing both contaminated kernels with a high contamination in a limited surface area (a few square millimetres) and kernels with a low contamination spread over a large surface area (up to 20 mm 2 ). Finally, the extensibility of our research methodology to other fluorescent mycotoxins is discussed.
