In the study, 290 different cereals and cereal products, sampled on Slovenian market under official control in the years 2008–2012, were investigated on the presence of mycotoxins. Altogether 40% of cereal samples contained one or more mycotoxins and 2.4% of them exceeded European Union maximum levels with one or more mycotoxins. Among all cereal foods, wheat and maize products could contribute most to the exposure of Slovenian inhabitants to mycotoxins, because of their relative high contamination rate, high share of samples exceeding EU maximum levels and by far the highest consumption, compared to other cereals. The highest incidence of positive and non-compliant results was with DON. The most frequently co-occurred mycotoxin combinations were DON-ZON in wheat, DON-T-2/HT-2 in oat and FB-DON and FB-DON-ZON in maize products. Concerning the incidence of non-compliant results there is no extreme differences from other EU results.

A validation of an analytical procedure for the determination of trichothecenes using gas chromatography-mass spectrometry was presented. Parameters of the procedure – the limit of detection, limit of quantification, repeatability, reproducibility, recovery and the measurement uncertainty were given. The results of the analysis of grain samples in the years 2007-2009 were presented. Of 175 samples, 74.3% contained at least one trichothecene. Most often, DON was present (in 70% of samples).

The validation of analytical procedure for the determination of aflatoxin B1 in eggs of laying hens was presented. The procedure consisted of the extraction of the analyte from the sample, immunoaffinity column clean-up and liquid chromatography with postcolumn bromination and fluorescence detection. The parameters obtained in the first (LOD 2 ng/kg, LOQ 6 ng/kg, RSDR 11%, izkoristek 70%) and in the second laboratory (LOD 2 ng/kg, LOQ 5 ng/kg, RSDr 20%, izkoristek 67%) indicate that both versions of the procedure are suitable for the determination of aflatoxin B1 in eggs of laying hens.

Several phytopathogenic Fusarium species occurring worldwide on cereals as causal agents of 'head blight' (scab) of small grain cereals and 'ear rot' of maize, are capable of accumulating, in infected kernels, several mycotoxins some of which of notable impact to human and animal health. Fusarium graminearum, F. culmorum, F. poae, F. avenaceum and Microdochium nivale predominantly cause Fusarium diseases of small-grain cereals. Maize is predominantly attacked by F. graminearum, F. moniliforme, F. proliferatum and F. subglutinans. The review is focused on the influence of climatic variables, particularly temperature, humidity and rainfall on growth, reproduction, survival, competitive ability, mycotoxicity and pathogenicity of Fusarium fungi commonly isolated from wheat, barley and maize.

The aim of the study was to determine the impact of pre-sowing seed treatment on wheat seed infection and contamination of produced grains from the field trial at the Biotechnical faculty (BF) and contamination of crop samples from Slovene farms with conventional and organic type of production. Seed treatment with fungicides had a greater influence on improving the health status of produced grain, compared to the preparations allowed in organic farming.
