Popis: In this study, five regularly consumed fermented foods: fermented melon (ogiri), locust beans (iru), African oil bean (ugba), maize meal (mahewu) and maize gruel (ogi) purchased from South African markets were evaluated for fungal diversity using 16S rRNA gene sequencing and mycotoxin contamination using liquid chromatography tandem mass spectrometry, respectively. In addition, their pH, moisture content, Total Titratable Acidity (TTA) and water activity were accessed. The investigation revealed a mean pH range of 3.60–8.14 within the samples and a significant but negative correlation between the pH and TTA (r = −0.560, p
