Mycotoxins are toxic compounds produced by fungal secondary metabolism that cause toxicological effects. Coffee is a highly popular beverage that is susceptible to contamination by mycotoxigenic fungi. The aim of the present study was to determine the presence of the following 21 mycotoxins in coffee using liquid chromatography tandem mass spectrometry (LC-MS/MS-IT): aflatoxin B-1, B-2, G(1) and G(2); ochratoxin A; nivalenol; deoxynivalenol; 3-acetyldeoxynivalenol; 15-acetyldeoxynivalenol; diacetoxyscirpenol; neosolaniol; T-2 and HT-2 toxin; sterigmatocystin; enniatin A, A(1), B, and B-1; beauvericin; and fumonisin B-1 and B-2. We aimed to determine differences by coffee process (coffee maker, electrical machine, soluble and traditional Turkish process) and to calculate the estimated daily intake (EDI) and risk assessment of mycotoxins from coffee consumption using deterministic approach at various scenarios of food consumption in Spanish adolescents and adults. The results demonstrate that all studied mycotoxins were detected in samples with mean concentrations ranging from 0.69 mu g/kg to 282.89 mu g/kg. Eleven percent of samples did not show contamination with legislated mycotoxins. Only 15-acetyldeoxynivalenol, deoxynivalenol, neosolaniol, fumonisin B-1, and ochratoxin A exhibited significant differences between methods of coffee brewing. The results show that coffee intake does not represent a potential risk for consumers with respect to individual mycotoxin contamination. (C) 2015 Elsevier Ltd. All rights reserved.
