title: Microbial and mycotoxic contamination of peppers and food safety.
abstract: Twelve random samples of pepper powders were analyzed for contamination by microorganisms of public health significance (bacteria, moulds) and for aflatoxin B1 concentration. Black peppers were more heavily contaminated than white peppers but the most important bacteria causing foodborne diseases were not isolated; The mould flora was dominated by xerophilic species, particularly Aspergillus fumigatus, A. flavus, A. niger and A. ochraceus. These potentially pathogenic species can be dangerous for predisposed patients. The most striking result concerns aflatoxin B1 which was detected in every sample analyzed and could not always be correlated with the occurrence of a mycotoxinogenic strain of Aspergillus, suggesting the use of a sterilizing treatment previously. So, the detection of aflatoxin B1 must be a necessary criterion to be added to microbial criteria to appreciate the quality of peppers.
