This study was carried out to evaluate the microbial load of dried pepper (Capsicum spp.), tomatoes (Lycopersicum esculentus), and roselle (Hibiscus Sabdariffa) sold at Minna, Niger state, Nigeria. An investigation was carried out for the isolation and identification of micro-organisms found in the selected dried vegetables. Total bacteria count in all the tested samples ranged from 2.0 x 104 to 7.0 x 104 cfu/g. Dried pepper showed the lowest amount of bacteria isolates/microbial load (Proteus spp. 7.0 x 104 and Kleb spp. 3.0 x 104) while the dry tomato showed the highest bacteria isolates (E.coli 3.0 x 104, Staphylococus 4.5 x 104 and Bacillus subtilis 3.5 x 104). Also in all the tested samples Asperigillus fumigates appeared as the most isolated fungi. It was clearly seen that all the tested samples were contaminated with different food borne pathogenic bacteria and fungi. Responsible authorities are advised to enlighten the public on how to maintain proper hygiene to avoid contaminations of these vegetables.
