Fresh cut street vended watermelon and pawpaw was analyzed for possible contamination with Salmonella and Listeria species was understudied using standard microbiological techniques. A total of twenty samples, (10) of pawpaw and (10) of watermelon were obtained from four different vendors located in Etta-Agbo, Watt, Goldie and Marian market. These were analyzed using the Compact Dry Plate, chromogenic media for the direct detection of these organisms selectively. The results revealed a high contamination level of the samples with Salmonella spp whereas all the pawpaw and watermelon samples analyzed were free of Listeria spp. The mean Salmonella spp count ranged between 2.1X103 to 5.7x105 cfu/g. The presence of this organism in the samples analyzed is a reflection of unwholesomeness and gross contamination of the fruits and are therefore unsafe for human consumption.
