Abstract


Bacteriological assessment of cassava products was carried out in three different main markets modern, wadata and Wurukum markets, all in Makurdi Benue State to determine bacterial contamination. The “Garri” and cassava chip samples were subjected to the pour method to determine the number of colonies and their densities, thus the extent of contamination and analysis of fecal indicators using presumptive, confirmatory and completed tests. Fine major bacteria isolated were Escherichia coli. Aerobacter aerogenes Salmonella species, Streptococcus faecalis and Staphylococcus aureus. In all the three markets, contamination of cassava chips and garri by E.coli was significantly (P<0.05) higher (30.8%) followed by salmonella species (24.8%). The higher percentage occurrence of E. coli in those cassava products may give an indication of faecal contamination of those products during processing or handling. More so, the highest occurrence of bacteria in “garri” and cassava chips from Wurukum and Wadata markets may be attributed to the poor sanitary condition of the markets and probably because of the processing methods and materials used in producing those products and poor wast disposal and management system.

Keywords: Bacteriological, Cassava-products, Contamination, Guinea-Savanna, Nigeria.
