Abstract: High microbial contamination of locally processed “kokonte” chips has been a concern, as its poor quality endangers the health of consumers sometimes with heat-resistant microbial toxins. The study assessed the extent of microbial contamination in “kokonte” chips produced from three processing methods in Ghana. Samples were purchased from “kokonte” producers in Volta Region (KCPV), cassava sellers in the Greater Accra Region (KCCA) of Ghana while Industry-processed (IP) “kokonte” samples were processed at the CSIR - Food Research Institute, Pokuase. Moisture content, Total Viable Count (TVC), Total Coliform Count (TCC), E. coli Count, and identification of microorganisms were determined using standard microbial techniques. The average TVC of samples from KCPV, KCCA and IP were log 7.560 ± 0.184 cfu/g, log 7.440 ± 0.573 cfu/g, and log 2.038 ± 0.409 cfu/g, respectively. The average TCC for the samples from KCPV and KCCA were log 1.452 ± 0.273 cfu/g and log 1.163 ± 0.733 cfu/g, respectively. The IP sample did not record any coliform. No E. coli was identified in the IP sample but KCPV sample recorded E. coli count of log 1.140 ± 0.180 cfu/g while samples from KCCA recorded E. coli count of log 0.550 ± 0.584 cfu/g. The locally-processed cassava chips, from KCPV and KCCP, recorded mould counts above log 6.00 cfu/g, however, the IP sample recorded mould count of log 1.200 ± 0.281 cfu/g. Corynebacterium spp., E. coli, Bacillus cereus, Salmonella spp., Proteus spp., Streptococcus spp., Bacillus subtilis, Staphylococcus aureus, Enterobacter spp., and Bacillus licheniformis were identified in KCPV. Mould isolates in the KCPV were Mucor spp., Rhizopus spp., Aspergillus niger, Fusarium spp. and Cryptococcus spp. The bacterial isolates in the KCCA samples were Corynebacterium spp., E. coli, Bacillus cereus, Salmonella spp., Proteus spp., Streptococcus spp., Bacillus subtilis, Staphylococcus aureus, Enterobacter spp., and Bacillus licheniformis. Mucor spp., Rhizopus spp., Aspergillus niger, Fusarium spp. and Cryptococcus spp. were the mould isolate recorded. Thus, the locally-processed samples were highly contaminated and may have serious health implications on consumers compared to the IP samples.
