Abstract

Seventeen imported raw spice samples obtained from retail outlets were examined for spoilage mould profile. A total of 665 fungal isolates, representing 14 species, were recovered and identified from dried and ground spice samples on several media using standard dilution plate method. Moisture content varied greatly among various samples and were generally high. The most heavily contaminated spice samples examined were observed in red chili and black pepper in order of magnitude of 1580 and 1120 cfu/g, respectively. The most predominant fungal genera encountered were Aspergillus, Penicillium, Rhizopus, Cladosporium and Trichoderma. Yeasts were also frequently recovered, but not identified. Relative occurrence values of taxa disclosed ranged between 36.4% for A. flavus and 0.6% for A. parasiticus and Absidia corymbifera. Samples obtained from gunny bags encounter higher colony counts and contamination frequency than other packing methods. The present magnitude of contamination and spectra of mycobiota approximate those reported for similar spice samples. Although several potentially mycotoxigenic fungi were isolated during the present study, neither the foodstuff nor the fungi were assayed for the presence of these toxins.
