Hazelnuts of three different categories, mouldy, hidden mould and sound (undamaged), were investigated for their contents of aflatoxins (B₁, B₂, G₁ and G₂), patulin, and ergosterol. Samples were obtained from five hazelnut processing plants located in a major hazelnut producing area in the Black Sea region in Turkey. All aflatoxins, patulin and ergosterol were determined by high performance liquid chromatography (HPLC). Sound hazelnuts were contaminated with trace or zero amounts of aflatoxins, patulin and ergosterol, so they posed no risk for the consumer when national and/or international regulatory limits were considered. Mouldy and hidden mould hazelnuts were contaminated with high (246-510 ppb; 141-422 ppb) aflatoxin levels, respectively. Aflatoxin B₁ content was significantly correlated with the patulin and ergosterol contents in mouldy and hidden mould hazelnuts. However, there was no significant correlation between patulin and ergosterol contents of mouldy and hidden mould hazelnuts.
