In this study 32 (3 in autumn, 11 in winter, 18 in spring) out of 138 tarhana samples (23.2%) were found to be contaminated with aflatoxins in the range of 0.7–16.8 μg/kg, whereas 29 out of 138 (21.0%) tarhana samples contained AFB1 ranging from 0.2–13.2 μg/kg (Table 3). According to these results, 14 tarhana samples exceeded the maximum limits of AFB1 (5 μg/kg) and total aflatoxin (10 μg/kg) set in the Turkish Food Codex [21] (Figure 3).
