Enumeration of Salmonella Species Isolated in Ready–to–Eat Fruits Vended in Bukuru Market, Jos South, Plateau State

Background: Despite control measures to curtailed salmonella fruit contamination over the years, pathogenic disease outbreaks caused by the ingestion of Salmonella contaminated fresh-cut-fruits pose a significant problem to human health by the consumption of fresh and minimally processed fruits. This study aimed to enumerate and determine the prevalence of Salmonella species isolated in ready-to-eat fruits vended in Bukuru Market Jos South, Plateau state. Methodology: A total of seventy-eight ready-to-eat vended fruit samples were purchased and cultured for the enumeration of bacterial isolates according to National Food Safety Standard for Microbiological Examination. Pulp pH value of each fruit was obtained by immersing litmus paper into the pulp and results recorded. Results: Of the 78 fruits specimen, 22 (28.2%) were Salmonella positive. The prevalence rates of salmonella isolated were found to be higher (22.7%) in both coconut and avocado followed by watermelon (18.2%) and sweetmelon (13.6%) as compared with other fruits in the study area. Lower rates of 4.5% were found in banana, pawpaw, and dates with a rise in apple with 9.1% respectively. Conclusion: The study showed a high p<0.05 (7.811) prevalence of pathogenic Salmonella species isolated in ready-to-eat fruits in the study area revealing that the spread of salmonella is not independent of fruits thereby suggestive of contamination made available by fruit vendors in this part of the world. Thus, epidemiological traceability and significant measures must be taken to check the safety of these vended products before consumption.
