en Occurrence and Exposure Assessment of Aflatoxin B1 and Ochratoxin A in Pearl Millet (Pennisetum glaucum L.) from Tunisia تخصصي Special Short communication Short communication <div style="text-align: justify;"><span style="font-family:Times New Roman;"><span style="font-size:14px;"><strong>Background: </strong>Ochratoxin A (OTA) and Aflatoxin B<sub>1</sub> (AFB<sub>1</sub>) are toxic secondary&nbsp; metabolites produced by certain mold species. In this primarily survey, we examined the OTA and AFB<sub>1 </sub>contamination of pearl millet grains distributed in Tunisia.<br> <strong>Methods:</strong> Twenty-five pearl millet (<em>Pennisetum glaucum </em>L.) samples from different regions of Tunisia were analyzed by High Performance Liquid Chromatography coupled with fluorescence detector in order to evaluate the contamination with of AFB<sub>1</sub> and OTA. <em>Statistical tests</em>&nbsp;were performed&nbsp;with XLSTAT 2018.<br> <strong>Results:</strong> AFB<sub>1</sub> and OTA were detected in 32 and 28% millet samples, respectively. Mean amounts of these mycotoxins in the contaminated samples were of 24.54&plusmn;17.54 &micro;g/kg for OTA and 22.72&plusmn;23.09 &micro;g/kg for AFB<sub>1</sub>. Approximately, 28 and 24% of analyzed samples were found above the European Union limits for AFB<sub>1</sub> and OTA, respectively. The estimated daily intake of OTA and AFB<sub>1</sub> were 3.76 and 3.89 ng/kg b.w. per day, respectively. No significantly (<em>p</em>>0.05) difference in OTA and AFB<sub>1</sub> contamination rate was found between samples taken from different regions.<br> <strong>Conclusion:</strong> Consumption of millet in Tunisia might be an important contributing factor to the risk of dietary exposure to OTA and AFB<sub>1</sub>.<br> <br> <strong>DOI:</strong> 10.18502/jfqhc.7.3.4148</span></span></div> Aflatoxin B1, Ochratoxins, Chromatography, High Pressure Liquid, Pennisetum, Tunisia 157 161 http://jfqhc.ssu.ac.ir/browse.php?a_code=A-10-954-1&slc_lang=en&sid=1 S.
