Pn OTA−: CFU from the atoxigenic P. nordicum strain; Pn OTA+: CFU from the toxigenic P. nordicum strain; SD: standard deviation. LOD = 0.04 μg/kg.
Different superscript letters indicate significant differences among OTA values.
values marked with an asterisk, fungal concentration was under the limit of detection (e.g., <3.00 Log CFU/cm² means that fungal concentration was inferior to 1.0 × 10³ CFU/cm²).
