* Positive samples were those > LOD, 0.03, 0.2, and 7.5 ng/mL (considering the dilution factor of extracts). Noncompliant samples were those > MRL, 2, 10, and 100 ng/mL for AFB₁, AOH, and TEA, respectively. Contamination level < LOD is indicated as zero concentration. Range and mean values are indicated for positive samples
