Aflatoxin producing fungi, such as Aspergillus, are common food contaminants, and various methods exist to detect their presence. Early detection of food contaminants is important and essentially required to prevent food spoilage during storage or transport, and thus reduce the economic impact caused by rejection of consignments. In this study, we have developed a probe based qPCR for detecting...
Humans and animals are exposed to aflatoxins, toxic carcinogenic fungal metabolites, through consumption of contaminated food and feed. Aspergillus flavus, the primary causal agent of crop aflatoxin contamination, is composed of phenotypically and genotypically diverse vegetative compatibility groups (VCGs). Molecular data suggest that VCGs largely behave as clones with certain VCGs exhibiting ...
A new reliable, fast, and simple method for the detection of aflatoxigenic Aspergillus strains, consisting of the addition of a cyclodextrin (a methylated beta-cyclodextrin derivative) to common media used for testing mycotoxin production ability, was developed. We propose the use of this compound as an additive for fungal culture media to enhance the natural fluorescence of aflatoxins. The pro...
The fungal population and distribution of aflatoxin-producing fungi in 30 samples of imported almond powder products purchased from retail markets were examined in this study. Total counts of fungi ranged from under 1.0 x 10 colony-forming units (CFU)/g to 8.5 x 10(3) CFU/g as determined with the dilution plating technique. The predominant fungi in the mould-contaminated almond samples were Asp...
