PREVALENCE OF SALMONELLA SPECIES CONTAMINATION RATE IN SOME SELECTED LOCALLY EDIBLE FRUITS IN OSOGBO, OSUN STATE
|
Fresh fruits remain essential components of human diet and there is considerable evidence of health and nutritional benefits associated with their consumption. This study was therefore designed to investigate the Prevalence of Salmonella species contamination rate in some selected locally edible fruits in Osogbo, Osun state. A cross-sectional study was conducted on two hundred and fifty (250) samples of three different conventional fruits namely Orange, Pawpaw and Watermelon sold in Osogbo, Osun State. The sampled locally edible fruits were analyzed for the presence, prevalence, susceptibility (sensitivity and resistant) patterns of Salmonella species and other bacteria to various antibiotics. The highest percentage of isolated Salmonella species was found in Watermelon (5.8%); followed by Orange (1.3%) and Pawpaw (1.2%). The most prevalent bacteria in all the fruits sampled were Staphylococcus albus. The prevalence rates as follows; Orange (38.8%); Pawpaw (34.8%) and Watermelon (33.3%). The multiple antibiotics resistance (MAR) and susceptibility pattern showed that Ofloxacin (100%) and Ciprofloxacin (100%) had the highest susceptible rate on Salmonella species isolated from the sampled fruits. Other microbial isolated includes Staphylococcus albus, Esherichia coli, Shigella species, Staphylococcus aureus and Proteus species. This investigation has shown that ready to eat locally edible fruits must be washed thoroughly with clean water before eating to avoid been contaminated with microorganisms.
